PROXY STATEMENT
FOR THE ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD AUGUST 25, 2010

July 9, 2010

This statement is furnished in connection with the solicitation on behalf of the Board of Directors of CommVault Systems, Inc. (which we refer to as we, us, our, CommVault or our company) of proxies to be voted at the Annual Meeting of Stockholders on August 25, 2010, or at any adjournment or postponement thereof. This proxy statement and the accompanying proxy card are first being made available at www.cfpproxy.com/6030 on or about July 9, 2010. A copy of our annual report on form 10-K for the fiscal year ended March 31, 2010, which includes audited financial statements, is also being made available concurrently with the proxy statement at www.cfpproxy.com/6030.

July 1, 2010 was the record date for the determination of stockholders entitled to vote at the Annual Meeting. On that date, 43,155,006 shares of common stock were outstanding and entitled to vote. Each stockholder is entitled to one vote for each share of common stock held of record. A list of stockholders entitled to vote at the Annual Meeting will be available for examination by stockholders during regular business hours at our principal executive offices located at 2 Crescent Place, Oceanport, New Jersey 07757 for 10 days preceding the meeting and also will be available for examination at the Annual Meeting.

Stockholders may provide voting instructions by completing, executing and returning the enclosed proxy card. Alternatively, stockholders may submit a proxy over the Internet or by telephone in accordance with the instruction set forth on the proxy card. All properly completed, unrevoked proxies received prior to the close of voting at the Annual Meeting will be voted in accordance with the instructions provided. If a properly executed, unrevoked written proxy card submitted by a record holder does not specifically direct the voting of shares, the shares represented by such proxy will be voted (i) FOR the election of all nominees for election as director described in this proxy statement, (ii) FOR the ratification of the appointment of Ernst & Young LLP as our independent public accountants for the fiscal year ending March 31, 2011, and (iii) in accordance with the judgment of the persons named in the proxy as to such other matters as may properly come before the Annual Meeting. If you are a beneficial owner of shares, the broker will ask you how you want your shares to be voted. If you give the broker instructions, the broker will vote your shares as you direct. If your broker does not receive instructions from you about how your shares are to be voted, one of two things can happen, depending on the type of proposal. Brokers who are members of the NYSE have discretionary power to vote your shares with respect to “routine” matters, but they do not have discretionary power to vote your shares on “non-routine” matters. Unlike in previous years, brokers holding shares beneficially owned by their clients will no longer have the ability to cast votes with respect to the election of directors unless they have received instructions from the beneficial owner of the shares. It is therefore important that you provide instructions to your broker so that your vote with respect to directors is counted.

A proxy may be revoked at any time prior to the voting at the Annual Meeting by submitting a later-dated proxy (including a later-dated proxy via the Internet or telephone), giving timely written notice of such revocation to the Secretary of our company or by attending the Annual Meeting and voting in person.

The presence at the Annual Meeting, in person or by proxy, of holders of a majority of the issued and outstanding shares of common stock as of the record date is considered a quorum for the transaction of business. If you submit a properly completed proxy or if you appear at the Annual Meeting to vote in person, your shares of common stock will be considered part of the quorum. Directions to withhold authority to vote for any director, abstentions and broker non-votes (described below) will be counted to determine if a quorum for the transaction of business is present. Once a quorum is present, voting on specific proposals may proceed.

Assuming the presence of a quorum, the affirmative vote of (1) a plurality of the votes cast at the Annual Meeting (in person or by proxy) is required for the election of directors, and (2) holders of a majority of the common stock present at the Annual Meeting (in person or by proxy) and entitled to vote is required to ratify Ernst & Young LLP as our independent public accountants for the fiscal year ending March 31, 2011.

Effect of Abstentions and Broker Non-Votes

Because the election of directors is determined on the basis of a plurality of the votes cast, abstentions have no effect on the election of directors. Because the approval of a majority of shares present and entitled to vote is required to ratify the appointment of Ernst & Young LLP as our independent public accountants, abstentions have the effect of a vote against the proposal.

If you hold shares through a broker or other nominee, your broker or nominee is permitted to exercise voting discretion only with respect to certain, routine matters. Broker non-votes are shares held by brokers or other nominees that do not have discretionary voting authority with respect to a matter and have not received specific voting instructions from the beneficial owner. Broker non-votes will be counted for purposes of establishing a quorum but will otherwise have no effect on the outcome of the vote on any of the matters presented for your vote.

Brokers who have not received voting instructions from beneficial owners may vote in their discretion with respect to Proposal No. 2 (the ratification of the appointment of our independent auditors).

PROPOSAL NO. 1

Our Board of Directors is divided into three classes, with one class of directors elected for a three-year term at each annual meeting. Each of Class consists of three directors. Each director holds office until the third annual meeting after the meeting at which such director is elected and until his or her successor is duly elected and qualified or until his or her earlier resignation, removal or death. The terms of the Class I Directors will expire at the 2010 Annual Meeting.

Upon the recommendation of the Nominations and Governance Committee, the Board of Directors has nominated Armando Geday, F. Robert Kurimsky and David F. Walker to hold office as Class I Directors until the annual meeting in 2013.

The persons named as proxy voters in the accompanying proxy card, or their substitutes, will vote your proxy for all the nominees, each of whom has been designated as such by the Board of Directors, unless otherwise indicated in your proxy. CommVault has no reason to believe that the nominees named herein will be unavailable to serve as directors. However, in the event that any nominee for director withdraws or for any reason is not able to serve as a director, we will vote your proxy for the remainder of those nominated for director (except as otherwise indicated in your proxy) and for any replacement nominee designated by the Nominations and Governance Committee of the Board of Directors.

You may vote for or withhold your vote from any or all of the director nominees. Assuming a quorum is present, the affirmative vote of the plurality of votes cast at the Annual Meeting (in person or by proxy) will be required for the election of directors.

As part of its annual review process, the Board of Directors monitors developments in the area of corporate governance. Listed below are some of the key elements of our corporate governance plan. Many of these matters are described in more detail elsewhere in this proxy statement.

The Board of Directors and Its Committees

General. Our Board of Directors currently comprises nine members, seven of whom are not officers of our company and two of whom are officers of our company. Our Board of Directors believes that our ratio of outside directors to inside directors represents a commitment to the independence of our Board of Directors and a focus on matters of importance to our stockholders.

Our Board of Directors has determined that Messrs. Frank J. Fanzilli, Jr., Armando Geday, Keith Geeslin, F. Robert Kurimsky, Daniel Pulver, Gary B. Smith and David F. Walker, all of the outside directors, are “independent” as that term is defined under the applicable listing standards of Nasdaq. In making this determination for each director, the Nominations and Governance Committee, on behalf of our Board of Directors, considered the standards of independence set forth in the Nasdaq Corporate Governance Listing Standards and all relevant facts and circumstances to ascertain whether there was any relationship between a director and our company that, in the opinion of the Nominating and Corporate Governance Committee, would interfere with the exercise of independent judgment in carrying out the responsibilities of the director, or any material relationship with our company (either directly, or as a partner, shareholder or other officer of an organization that has a relationship with our company).

During the year ended March 31, 2010, our Board of Directors held 5 meetings. All of our directors who served in the year ended March 31, 2010, attended all meetings of the Board of Directors and all meetings of the committees of the Board held and on which the director served. The Board of Directors is scheduled to meet in executive session, without management, at every Board meeting that the directors attend in person. Mr. Smith acts as lead independent director to chair these executive sessions and as primary spokesperson in communicating matters arising out of these sessions to our management.

Directors are encouraged to attend our annual meeting.

The Board of Directors has three standing committees. These committees have the responsibilities and authority described later in this section.

Board Leadership Structure. CommVault’s policy regarding its leadership structure is to adopt the practice which best serves our company’s needs at any particular time. Our Board has currently determined that the most effective leadership structure for our company is for N. Robert Hammer to serve as both Chairman and Chief Executive Officer.

Mr. Hammer has consistently provided strong leadership to our company and Board since becoming Chairman and Chief Executive Officer in March 1998. His strategic vision and financial discipline have been integral to our company’s growth. Mr. Hammer’s dual role provides the opportunity for better decision making and Board leadership given the greater level of information provided through his access to both management and the Board. The dual role provides a high level of communication between management and the Board on all matters and capitalizes on Mr. Hammer’s successful history in leading both our company and the Board. The Board currently believes having on person sere as both Chief Executive Officer and Chairman of the Board also eliminates the potential of duplication of efforts and inconsistent actions, enabling the Board and management to work effectively toward the same goals and strategy.

While Mr. Hammer serves as Chairman, strong independent Board leadership is exerted by our lead independent director, Gary B. Smith, who provides additional support to the corporate governance structure. Under our Corporate Governance Policies, the lead independent director is responsible to coordinate the activities of the other independent directors and to fulfill other responsibilities established by the Board or the independent directors. Currently, our lead independent director’s specific responsibilities include presiding at executive sessions of the Board and facilitating communication between Board members and the Chairman. Our lead director also communicates to the CEO on issues identified by the other independent directors. As a member of the Nominations and Governance Committee, Mr. Smith participates in the annual Board performance evaluation process and in the assessment of our company’s Governance Policies. The lead independent director, and many of the other directors, communicates with the Chairman and Chief Executive Officer regarding appropriate agenda topics and other board related matters. In accordance with our Corporate Governance Policies, no director may serve as lead independent director for more than five consecutive years.

Board Oversight of Risk. Our company’s policies and procedures relating to risk assessment and risk management are overseen by its Board of Directors. A fundamental part of risk assessment and risk management is not only understanding the risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for our company. The involvement of the Board in setting our company’s business strategy is a key part of its assessment of management’s risk tolerance and what constitutes an appropriate level of risk for our company. The Board of Directors considers risk management to varying degrees regularly at its meetings. The Board will adjust its practices with respect to risk oversight whenever it determines it needs to do so and will involve itself in particular areas or business circumstances where its proper exercise of oversight requires it.

While the Board of Directors has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk assessment and risk management. The Audit Committee is required under its charter to inquire of management and the independent auditor concerning significant financial risks or exposures and to assess the steps management has taken to minimize such risks. The Audit Committee also oversees our company’s internal audit function and reviews with the General Counsel any legal matters, including litigation, that may have a material impact on our company’s financial statements, financial condition or results of operations. In addition, the Compensation Committee assesses compensation related risk and the Nominations and Governance Committee addresses management and governance risk, including through its oversight of the succession planning process. Each of these Board committees reports to the full Board with respect to its risk oversight functions.

At the management level, our company has established a disclosure committee to monitor our company’s compliance with its disclosure obligations under law and Nasdaq regulations and an executive review committee to monitor and approve certain transactions or other corporate matters that deviate from our company’s standard practices. The senior management of our company report to the Board or Board committees regarding risk issues, including those identified by the foregoing committees. In accordance with our company’s Corporate Governance Policies, the Board has complete and open access to any member of our company’s management and any of our company’s employees, as well as any outside advisors or independent advisors retained by the Board. In addition, our company’s Chief Financial Officer and General Counsel are available at Board and committee meetings to answer questions relating to risk oversight. Further, because the Chief Executive Officer and Chief Operating Officer are directors, they bring a unique perspective on our company’s risk profile and risk assessment to Board deliberations based on their day to day management responsibilities.

Audit Committee. The Audit Committee is responsible for the appointment of, compensation of and oversight over the work of our independent auditor. Additionally, the Audit Committee monitors the integrity of our financial statements, our independent auditor’s qualifications and independence, our compliance with legal and regulatory requirements and the performance of our internal audit function and independent auditor. The Audit Committee relies on the knowledge and expertise of our management, the internal auditors and the independent auditor in carrying out its oversight responsibilities. The members of the Audit Committee are Messrs. Walker (Chairman), Kurimsky and Pulver. The Audit Committee is comprised solely of directors who meet all of the independence standards for audit committee membership as set forth in the applicable listing standards of Nasdaq. The Board of Directors has determined that Mr. Walker qualifies as an “audit committee financial expert” as that term is defined in the SEC rules adopted pursuant to the Sarbanes-Oxley Act of 2002, and that each Audit Committee member has sufficient knowledge in financial and auditing matters to serve on the Audit Committee.

The Audit Committee operates under a written charter. The Audit Committee held 5 meetings in the year ended March 31, 2010. A report of the Audit Committee appears elsewhere in this proxy statement.

Compensation Committee. The Compensation Committee is responsible for overseeing our compensation and benefit plans, including all compensation arrangements for executive officers and directors. The members of the Compensation Committee are Messrs. Geeslin (Chairman), Fanzilli and Geday. The Compensation Committee is comprised solely of outside directors who meet the independence standards for compensation and nominating committee members as set forth in Nasdaq listing standards.

Management assists the Compensation Committee in the performance of its duties. Each year, the Chief Executive Officer reviews the performance and compensation of each of the executive officers and makes recommendations to the Compensation Committee with respect to the executive officers’ compensation.

The Compensation Committee has the authority to engage its own independent advisors to assist in carrying out its responsibility. From time to time, consultants, including Radford Surveys + Consulting, also provide additional services at the request of our company. In fiscal year 2010, these services included assistance and advice in the formulation of our company’s equity compensation program and the calculation of restricted stock awards and appropriate target awards for participants, which services were provided at the request of management and which were not approved by the Board or the Compensation Committee.

The Compensation Committee operates under a written charter. The Compensation Committee met 4 times in the year ended March 31, 2010. Also, the Compensation Committee, or a sub-committee thereof, acted by unanimous written consent 13 times during fiscal year 2010. A report of the Compensation Committee appears elsewhere in this proxy statement. For a more detailed discussion of the Compensation Committee’s processes and procedures for considering and determining executive compensation, see “Executive Compensation — Compensation Discussion and Analysis.”

Nominations and Governance Committee. The Nominations and Governance Committee is responsible for identifying and recommending to our Board of Directors appropriate director nominee candidates and providing oversight with respect to corporate governance matters, including reviewing our corporate governance policy. The members of the Nominations and Governance Committee are Messrs. Pulver (Chairman), Kurimsky, Smith and Walker. The Nominations and Governance Committee is comprised solely of outside directors who meet the independence standards for compensation and nominating committee members as set forth in Nasdaq listing standards.

The Nominations and Governance Committee is responsible for assessing the appropriate balance of experience, skills and characteristics required of our Board of Directors and for carrying out adequate due diligence with respect to prospective board members. The Nominations and Governance Committee will consider nominees that are recommended by members of the Board of Directors, management or other stockholders. Nominees for director shall be selected on the basis of depth and breadth of experience, integrity, ability to make independent analytical inquiries, understanding of our business environment, the willingness of the candidate to devote adequate time to board duties, the interplay of the candidate’s experience and skills with those of other board members, and the extent to which the candidate would be a desirable addition to our Board of Directors and any committees of the Board.

If the Nominating and Corporate Governance Committee receives, prior to the date that is 120 days before the anniversary of the date of mailing for the prior year’s proxy statement, a nominee recommendation from a stockholder or group of stockholders that has beneficially owned more than 5% of our company’s voting common stock for at least one year as of the date of the recommendation, the name of the candidate, the name(s) of the stockholder(s) who recommended the candidate and whether the Nominating and Corporate Governance Committee chose to nominate the candidate will be disclosed in the proxy statement, if the consent of both the stockholder and the candidate has been received.

If a stockholder desires to nominate persons for election as director at any stockholders’ meeting duly called for the election of directors, written notice of the stockholder’s intent to make such a nomination must be given and received by the Secretary at our principal executive offices either by personal delivery or by United States mail not later than (i) with respect to an annual meeting of stockholders, 90 days prior to the anniversary date of the date on which notice of the prior year’s annual meeting was mailed to stockholders, and (ii) with respect to a special meeting of stockholders, the close of business on the tenth day following the date on which notice of such meeting is first sent or given to stockholders.

Each notice shall describe the nomination in sufficient detail for the nomination to be summarized on the agenda for the meeting and shall set forth:

	•		the name and address, as it appears on our books, of the stockholder who intends to make the nomination;
	•		a representation that the stockholder is a holder of record of our stock entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to present such nomination;
	•		whether the stockholder plans to deliver or solicit proxies from other stockholders;
	•		the class and number of our shares which are beneficially owned by the stockholder;
	•		the name and address of any person to be nominated;
	•		a description of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the stockholder;
	•		such other information regarding such nominee proposed by such stockholder as would be required to be included in a proxy statement filed pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended; and
	•		the consent of each nominee to serve as a Director of our company if so elected.

The Nominations and Governance Committee operates under a written charter. The Nominations and Governance Committee met or took action 3 times in the year ending March 31, 2010.

Stockholder Communication Policy. Stockholders can contact our Board of Directors to provide comments, to report concerns, or to ask a question, at the following address.

Corporate Secretary
CommVault Systems, Inc.
2 Crescent Place
Oceanport, New Jersey 07757

You may submit your concern anonymously or confidentially by postal mail.

Communications are distributed to our Board of Directors, or to any individual directors as appropriate, depending on the facts and circumstances outlined in the communication. You may also communicate online with our Board of Directors as a group through our website at www.commvault.com.

Board Diversity. The Board of Directors has adopted a policy on Board diversity to be implemented by the Nominations and Governance Committee. This policy requires the Nominations and Governance Committee to consider diversity in professional experience, skills, broad-based business knowledge, understanding of our company’s business environment and training when recommending Director nominees to the Board, with the objective of achieving a board with diverse business and educational backgrounds. It is the goal of this policy for the Board to be composed of members with individual backgrounds that, when combined, provide a portfolio of experience and knowledge that will serve our company’s governance and strategic needs. In accordance with our company’s Corporate Governance Guidelines, the Nominations and Governance Committee will consider the interplay of the director candidate’s experience and skills with those of other Board members, as well as the extent to which the candidate would be a desirable addition to the Board and any Committees of the Board. When recommending nominees for Director, the Nominations and Governance Committee does not discriminate against candidates based on gender, ethnicity, religion or national origin. Our company’s Board diversity policy specifies that the Nominations and Governance Committee will review the skills and attributes of Board members within the context of the current make-up of the full Board from time to time as the Nominations and Governance Committee deems appropriate. In connection with its deliberations with respect to Director nominations for our company’s 2010 annual meeting, the Nominations and Governance Committee assessed that it effectively nominates candidates for Director in accordance with the above described standards, with the current Board being composed of individuals with finance, accounting, technology, management and international experience. See each nominee’s and director’s biography appearing earlier in this proxy statement for a description of the specific experience that each such individual brings to the Board.

Transactions with Related Persons

The Board of Directors recognizes that transactions between us and certain related persons present a heightened risk of conflicts of interest. It is our policy to have the Nominations and Governance Committee review and approve, ratify or disapprove of proposed transactions or courses of dealings with respect to which executive officers or directors or members of their immediate families have an interest (including all transactions required to be disclosed pursuant to the SEC’s related persons disclosure requirements (“Related Persons Transactions”). The Nominations and Governance Committee is to review such transaction based upon the rules of Nasdaq and upon the Nominations and Governance Committee’s review of our ethics and governance guidelines. We did not enter into any Related Persons Transactions during the year ended March 31, 2010.

We have a Code of Business Ethics and Conduct, a copy of which is posted on our web page at www.commvault.com, which applies to all of our employees. The Code, among other things, has a policy governing conflicts of interests generally and, in particular, prohibiting employment or other activities in certain other businesses, soliciting clients for any other purpose or relationships that may be perceived as impairing the ability of the individual or our company from performing his or its duties, as the case may be, in an impartial manner, and use of corporate property for improper personal gain. Any complaints or concerns require disclosure to the Vice President, General Counsel or Vice President, Human Resources and, if warranted, to the Audit Committee or Nominations and Governance Committee.

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors and executive officers and beneficial owners of 10 percent or more of a registered class of our equity securities to file with the SEC initial reports of beneficial ownership (Form 3) and reports on changes in beneficial ownership (Form 4 or 5). SEC rules adopted pursuant to Section 16(a) require that such persons furnish us with copies of all such forms they file with the SEC.

Based solely upon our review of such forms furnished to us during the year ended March 31, 2010, and upon the written representations received by us from certain of our directors and executive officers, we believe that our officers and 10% stockholders complied with all Section 16(a) filing requirements on a timely basis during the year ended March 31, 2010. Our directors each had one late filing related to the receipt of their partial year equity award.

The following table shows, as of June 30, 2010, the number of shares of our common stock, par value $.01 per share (the only class of voting securities outstanding), beneficially owned by: (1) each director and nominee for director; (2) each named executive officer (defined below); and (3) all directors and executive officers as a group. The number of shares of our common stock beneficially owned by a person includes shares of commons stock issuable with respect to options, restricted stock units and convertible securities held by the person which are exercisable, convertible or will vest within 60 days. The percentage of our common stock beneficially owned by a person assumes that the person has exercised all options, vested in restricted stock units and converted all convertible securities, the person holds which are exercisable, convertible or will vest within 60 days, and that no other persons exercised any of their options, vested in any of their restricted stock units or converted any of their convertible securities.

The Compensation Committee of the Board of Directors, or the Compensation Committee, has responsibility for establishing, implementing, and continually monitoring adherence with our company’s compensation philosophy. Its duties include:

•

setting the total compensation of our Chief Executive Officer and evaluating his performance based on corporate goals and objectives;

•

reviewing and approving the Chief Executive Officer’s decisions relevant to the total compensation of our company’s other executive officers;

•

making recommendations to the Board of Directors with respect to equity-based plans in order to allow us to attract and retain qualified personnel; and

•

reviewing director compensation levels and practices, and recommending, from time to time, changes in such compensation levels and practices to the Board of Directors.

The members of our compensation committee are Messrs. Fanzilli, Geeslin and Geday. Mr. Geeslin currently serves as Chairman of the Compensation Committee. Each member of the Compensation Committee is an “independent director” as such term is defined by Nasdaq’s Marketplace Rules. The Compensation Committee meets at scheduled times during the year and meets on an as necessary interim basis. Additionally, the Compensation Committee considers and takes action by written consent. The Compensation Committee met four times during fiscal year 2010. Also, the Compensation Committee, or a sub-committee thereof, acted by unanimous written consent 13 times during fiscal year 2010.

Compensation Philosophy and Objectives

As a growing high-technology company, we operate in an extremely competitive and rapidly changing industry. We believe that the skill, talent, judgment and dedication of our executive officers are critical factors affecting the long-term value of our company. The Compensation Committee’s philosophy and objectives in setting compensation policies for executive officers are to align pay with performance, while at the same time providing fair, reasonable and competitive compensation that will allow us to retain and attract superior executive talent. The Compensation Committee strongly believes that executive compensation should align executives’ interests with those of shareholders by rewarding achievement of specific annual, long-term, and strategic goals by our company, with the ultimate objective of improving long-term stockholder value. The specific goals that our current executive compensation program rewards are focused primarily on revenue growth and profitability. To that end, the Compensation Committee believes executive compensation packages provided by our company to its executive officers should include a mix of both cash and equity-based compensation that reward performance as measured against established goals. As a result, the principal elements of our executive compensation are base salary, non-equity incentive plan compensation, long-term equity incentives generally in the form of stock options and/or restricted stock and post-termination severance and acceleration of equity award vesting for certain named executive officers upon termination and/or a change in control.

Our goal is to maintain an executive compensation program that will fairly compensate our executives, attract and retain qualified executives who are able to contribute to our long-term success, induce performance consistent with clearly defined corporate goals and align our executives’ long-term interests with those of our shareholders. The decision on the total compensation for our executive officers is based primarily upon an assessment of each individual’s performance and the potential to enhance long-term stockholder value. Often, judgment is relied upon and not upon rigid guidelines or formulas in determining the amount and mix of compensation for each executive officer. Factors affecting such judgment include performance compared to strategic goals established for the individual and our company at the beginning of the year, the nature and scope of the executive’s responsibilities, and effectiveness in leading initiatives to achieve corporate goals.

The Compensation Committee is responsible for setting the compensation of our Chief Executive Officer and also reviewing and approving our Chief Executive Officer’s decisions relevant to the compensation of our other executive officers. Our Chief Executive Officer, Chief Financial Officer and Vice President of Human Resources support the Compensation Committee in its work by providing information relating to our financial plans, performance assessments of our executive officers and other personnel-related data. In addition, the Compensation Committee has authority under its charter to engage outside advisors and experts for advice as appropriate.

In the second quarter of fiscal 2010, the Company and our Compensation Committee jointly engaged Radford Surveys + Consulting (which we refer to as Radford) to conduct a review and provide peer analysis information for structuring our base salary and non-equity incentive plan compensation programs. The Compensation Committee and management used this data to ensure that our compensation programs are optimally structured to retain our highly experienced executive management team, to keep management focused during our expected period of growth, to motivate management to maximize stockholder value and to align our compensation practices with other technology industry companies of similar size. Radford provided compensation survey data from 31 technology industry companies with annual revenue in the range of $130 million to $520 million. The list of companies included in the survey were 3PAR, Advent Software, Inc., Ariba, Inc., Blue Coat Systems, Inc., Concur Technologies, CSG Systems International, Inc., Cybersource, Data Domain, Digital River, Inc., Eclipsys Corp., Emulex, Exponent, Inc., Extreme Networks, Inc., I2 Technologies, Inc., Infinera Corp., Informatica Corp., Limelight Networks, Progress Software Corp., QAD, Inc., Radiant Systems, Inc., RightNow Technologies, Riverbed Technology, Inc., Rovi Corp., S1 Corp., Silicon Graphics Int’l Corp., SkillSoft Public Limited Co., SPSS, Inc., Synaptics, Inc., Syniverse Holdings, Inc., Websense, Inc., and Wind River Systems, Inc. The results of the Radford survey data and the subsequent recommendations were presented to the Compensation Committee as part of our fiscal 2010 executive compensation decisions for base salary and non-equity incentive compensation which were awarded in October 2009 and for long-term equity incentive compensation which was awarded in December 2009.

The principal components of compensation for our executive officers are:

•

Base salary;

•

Non-equity incentive plan compensation;

•

Long-term equity incentives; and

•

Other benefits

We provide our executive officers and other employees with base salary to compensate them for services rendered during the fiscal year. We believe that our base salaries are competitive and we generally target our executive officer base salaries against the 50^th – 75^th percentile of the technology industry survey data obtained. We target this range because we have historically achieved revenue and earnings growth that is in the top tier of companies in our industry. In some circumstances it may be necessary to provide compensation above these levels; these circumstances include the need to retain key individuals, to recognize roles that were larger in scope or accountability than standard market positions and/or to reward individual performance.

Salary levels are typically reviewed annually each April as part of our performance review process as well as upon a promotion or other change in job responsibility. However, in April 2009 we elected not to increase the base salaries of our executive officers primarily as a result of the general state of the economy at that time. In October 2009, after it became increasingly clear that both the economy and our business was stabilizing, we performed a base salary merit review for each of our executive officers. In addition to considering the analysis provided by Radford discussed above, the Compensation Committee considered the scope of and accountability associated with each executive officer’s position; the performance of each executive officer during fiscal 2009 and the first half of fiscal 2010; and the overall experience of each executive officer when approving the base salary levels that became effective in October 2009. For fiscal 2010, the base salaries accounted for approximately 21% of total compensation for our Chief Executive Officer and 29% for our other named executive officers. The table below shows the fiscal 2009 and 2010 base salary rates for each named executive officers:

		Fiscal 2009				Fiscal 2010				Amount of				Percentage

Non-Equity Incentive Plan Compensation

Non-equity incentive plan compensation for our executive officers is designed to reward performance against key corporate goals. In early fiscal 2010, the non-equity incentive plan compensation targets for that year were approved after considering targets for comparable positions provided by our external compensation consultant discussed above; the scope of and accountability associated with each executive officer’s position; and the performance and experience of each executive officer. The performance metrics against which our executive officers are measured are clearly communicated, consistently applied and are focused on corporate objectives. Our executive officer incentive targets are designed to motivate management to achieve specific goals related to certain revenue and profitability objectives. These metrics were selected because we believe that, at this stage of our development, they are most closely correlated to increasing stockholder value. We believe that our revenue and profitability goals are aggressive and not easy to achieve because they are based on growth objectives higher than the industry average. Prior to fiscal 2010, only one time in the previous five fiscal years had any of our named executive officers achieved a non-equity incentive plan award that was greater than 100% of their target. During fiscal 2010, our actual revenue and profitability growth rates resulted in non-equity incentive awards ranging from 96% to 115% of the targets set for our named executive officers.

Mr. Hammer — Fiscal 2010 Non-Equity Incentive Compensation

Our Chief Executive Officer, Mr. Hammer, is eligible for non-equity incentive plan compensation with a target bonus potential equal to 100% of his $467,000 base salary for fiscal 2010. Mr. Hammer’s target bonus is based on our company’s total revenue and non-GAAP income from operations achievement against the annual financial plan approved by our Board of Directors in which each performance measure is weighted equally. The Compensation Committee evaluates Mr. Hammer based on these performance metrics because we currently believe that growth in revenue and non-GAAP income from operations drives our ability to increase stockholder value. Non-GAAP income from operations excludes noncash stock-based compensation charges and additional FICA expense incurred when employees exercise in the money stock options or vest in restricted stock awards. We use non-GAAP income from operations internally to understand, manage and evaluate our business as well as to make operating decisions.

The terms of Mr. Hammer’s fiscal 2010 non-equity incentive plan contained both minimum threshold amounts that must be achieved to qualify for an award as well as additional payment amounts for surpassing the performance metrics. Specifically, actual results below 75% of revenue and below 60% of non-GAAP income from operations result in no payment for the respective target. Actual results at 75% of the revenue target result in a 50% payout for that component and actual results at 60% of non-GAAP income from operations result in a 60% payout for that component. For fiscal 2010, the total revenue achievement needed to obtain the minimum threshold payout of $116,750 on the revenue component was $198.8 million. For each additional $13.2 million, or 5%, that the revenue achievement is above $198.8 million, the resulting payout increases by approximately $23,350. The total non-GAAP income from operations achievement needed to obtain the minimum threshold payout of $140,100 on the non-GAAP income from operations component was $23.8 million. For each additional $4.0 million, or 10%, that the non-GAAP income from operations achievement is above $23.8 million, the resulting payout increases by approximately $23,350.

Actual revenue for fiscal 2010 was $271.0 million and actual non-GAAP income from operations was $47.3 million. As a result, Mr. Hammer was awarded $522,442, or approximately 112% of his fiscal 2010 target bonus amount, related to achievement against his total revenue and non-GAAP income from operations performance targets.

Our Chief Operating Officer, Alan Bunte, and our Chief Financial Officer, Louis Miceli, are also eligible for non-equity incentive plan compensation with a target bonus potential equal to a percentage of their base salaries. For fiscal 2010, Mr. Bunte’s target bonus was 75% of his $350,000 base salary and Mr. Miceli’s target bonus was 50% of his $309,000 base salary. Non-equity incentive plan compensation awarded to Messrs. Bunte and Miceli is determined and approved by Mr. Hammer and reviewed by the Compensation Committee. The performance goals for Messrs. Bunte and Miceli are both quantitative and qualitative. With respect to quantitative goals for fiscal 2010, Messrs. Bunte and Miceli were measured against the same performance objectives as Mr. Hammer. However, Mr. Hammer also considers achievement against qualitative objectives which are subjective in nature. Therefore, the ultimate non-equity incentive compensation achievement percentage awarded to Messrs. Bunte and Miceli may be either higher or lower than that of Mr. Hammer’s strictly quantitative calculation. Mr. Hammer does not use a specific formula or apply specific weights when evaluating performance and the resulting impact that such qualitative objectives have on the overall non-equity incentive compensation payout. Instead, Mr. Hammer uses his business judgment to determine an appropriate award after considering both the quantitative and qualitative objectives. Among the most important qualitative factors that Mr. Hammer uses to evaluate the performance of Messrs. Bunte and Miceli are: innovation; leadership; strategic planning; product development initiatives and achievements; financial and operational excellence; customer satisfaction; and staff development.

Mr. Hammer awarded Mr. Bunte a fiscal 2010 non-equity incentive award that was 115% of his target bonus amount resulting in a non-equity incentive plan compensation of $301,875, or 86%, of his base salary. In determining Mr. Bunte’s bonus award, Mr. Hammer considered the following achievements in addition to the financial performance of our company. During fiscal 2010, Mr. Bunte continued to successfully lead the product development team in making significant progress in our next generation software release. We believe that our next generation software release will be the largest release in our history and will dramatically enhance our leading technology positions in both data and information management. In addition, Mr. Bunte led our business and finance operation teams throughout fiscal 2010 in making critical resource and related investment decisions during the economic downturn in order to manage overall spending and increase profitability. Finally, during fiscal 2010, Mr. Bunte continued to strengthen our best in class customer support organization by maintaining customer satisfaction ratings that we believe are significantly higher than industry average. Mr. Hammer awarded Mr. Miceli a fiscal 2010 non-equity incentive award that was 102% of his target bonus amount resulting in a non-equity incentive plan compensation of $157,590, or 51%, of his base salary. In determining Mr. Miceli’s bonus award, Mr. Hammer considered the following achievements in addition to the financial performance of our company. Mr. Miceli successfully led CommVault’s worldwide finance organization during fiscal 2010 and worked closely with Mr. Hammer and Mr. Bunte to lead company-wide efforts focused on cost reductions to help offset the impact that the worldwide economic downturn had on CommVault’s financial results. In addition, during fiscal 2010 Mr. Miceli led significant enhancements to CommVault’s control environment and transactional processes such as additional streamlining of CommVault’s customer support renewal process and providing other revenue enhancement opportunities.

Our Vice President of Sales, Americas, Ron Miiller, is eligible for a quarterly non-equity incentive plan compensation award based on a percentage of software revenue recognized during each quarter of the fiscal year. Mr. Miiller’s non-equity incentive plan compensation is a tiered commission based plan where he is rewarded for software revenue achievement in the United States, South America, Canada and Mexico. Based on the software revenue targets provided for the United States, South America, Canada and Mexico, Mr. Miiller’s target non-equity incentive plan compensation potential for fiscal 2010 was $67,250 per quarter, or a total annual amount equal to 100% of his base salary. No payment is made for less than 70% achievement of the target software revenue amount. The following table details the relationship between the percentage of the software revenue target achieved to the percentage of the $67,250 quarterly commission award earned.

		Target Achieved in Relation to Commission Award Earned
Percentage of target software revenue achieved			70	%			75	%			80	%			85	%			90	%			95	%			100	%
Percentage of commission award earned			40	%			50	%			60	%			70	%			80	%			95	%			100	%

The maximum quarterly commission payout allowed under Mr. Miiller’s compensation plan is 100% of the applicable software revenue target. In addition, half of any commission dollar amount not earned in a particular quarter due to underperformance is added to the following quarter’s targeted commission amount that is eligible to be earned. In order to provide an additional incentive for significant over-achievement of the software revenue attained, Mr. Miiller was eligible for an annual over-achievement bonus that contains an additional pay-out up to $100,000, or approximately 37% of his base salary.

Mr. Miiller was awarded $274,632, or 102% of his target commission award for fiscal 2010. In addition, Mr. Miiller qualified for an additional $50,000 for his over-achievement against his fiscal 2010 targeted software revenue. As a result, Mr. Miiller earned a total of $324,632, or 121% of his target commission award, in non-equity incentive plan compensation for fiscal 2010.

For our executives with geographic specific incentive plans, we do not disclose the specific quarterly targets and related achievement against such quarterly targets. Our geographic software revenue targets are highly confidential and are not reported publicly. Disclosing specific geographic business unit targets would cause substantial harm to our competitive position as it would allow our competitors to reach conclusions related to geographic plans for growth, profitability, allocation of resources and changes in direction. We believe this would give competitors an unfair advantage and could result in a materially adverse impact on our stock price and negatively affect our stockholders. We believe that the performance targets set for Mr. Miiller are challenging and require substantial effort in order to be attained which is evidenced by Mr. Miiller’s historical achievements against his software revenue target of 88% in fiscal 2008, 79% in fiscal 2009 and 102% in fiscal 2010. Mr. Miiller’s compensation plan includes quarter over quarter sequential growth targets that we believe are important to sustain consistent software revenue growth over prior year actual amounts.

Mr. West — Fiscal 2010 Non-Equity Incentive Compensation

Our Vice President of Marketing and Business Development, David West, is eligible for non-equity incentive plan compensation with a target bonus potential equal to 70% of his $260,000 base salary for fiscal 2010. Mr. West’s non-equity incentive compensation plan award is calculated based on a percentage of worldwide software revenue; software revenue specifically generated through our original equipment manufacturers; software revenue generated specifically from our operations in China; and funnel inflow. Software revenue generated through our original equipment manufacturers primarily relate to our agreements with Dell and Hitachi Data Systems. Our original equipment manufacturers sell our software applications and in some cases incorporate our data and information management software into systems that they sell. Funnel inflow is defined as the net new forecasted software revenue opportunities being tracked by our sales and marketing teams on a worldwide basis during the fiscal year. Mr. West’s non-equity incentive plan compensation is calculated on a semi-annual basis but is paid on an annual basis. Mr. West’s non-equity incentive plan was most heavily weighted toward software revenue because he is primarily responsible for supporting our software revenue growth. As a result, Mr. West’s fiscal 2010 non-equity incentive plan was weighted 57% to worldwide software revenue; 22% to software revenue specifically generated through our original equipment manufacturers; 14% to software revenue specifically generated through our operations in China; and 7% to worldwide funnel inflow.

Under the terms of Mr. West’s fiscal 2010 non-equity incentive plan, no payment is made for less than 70% achievement of each applicable targeted amount. The following table details the relationship between the achievement percentage of each performance metric to the non-equity incentive plan award earned.

		Target Achieved in Relation to Award Earned
Each individual performance metrics
Percentage of target achieved			70	%			75	%			80	%			85	%			90	%			95	%			100	%			110	%			115	%			120	%			125	%

The maximum annual payout allowed under Mr. West’s non-equity incentive plan is 125% of the applicable targeted amount. In addition, half of any semi-annual bonus amount not earned at the mid-year calculation due to underperformance is added to the second half targeted bonus amount that is eligible to be earned. Mr. West was awarded $175,000, or 96% of his target non-equity incentive award for fiscal 2010.

For our executives with geographic and operational specific incentive targets, we do not disclose the specific targets and related achievement against such targets. Our geographic software revenue and operational specific targets are highly confidential and are not reported publicly in a manner consistent with Mr. West’s non-equity incentive plan compensation. Disclosing specific geographic business unit and operational targets would cause substantial harm to our competitive position as it would allow our competitors to reach conclusions related to geographic plans for growth, profitability, allocation of resources and changes in direction. We believe this would give competitors an unfair advantage and could result in a materially adverse impact on our stock price and negatively affect our stockholders. We believe that the performance targets set for Mr. West are challenging and require substantial effort in order to be attained which is evidenced by Mr. West’s historical consolidated achievement against such targets of 62% in fiscal 2008, 57% in fiscal 2009 and 96% in fiscal 2010. Mr. West’s non-equity incentive plan compensation includes sequential growth targets that we believe are important to sustain consistent revenue growth over prior year actual amounts.

To date, the Compensation Committee has not exercised discretion to increase or reduce the award amounts that resulted from the application of our non-equity incentive plan compensation. However, the committee has the authority to do so if it determines that an adjustment would serve our interests and the goals of our executive officer non-equity incentive plan compensation.

Long-Term Equity Incentive Awards

We currently provide long-term equity incentive compensation pursuant to our 2006 Long-Term Stock Incentive Plan (the “LTIP”). The LTIP permits the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance stock awards and stock unit awards based on, or related to, shares of our company’s common stock. As of March 31, 2010, we have only granted non-qualified stock options and restricted stock units under the LTIP to our executive officers. We anticipate that future grants under the LTIP will also include both non-qualified stock options and restricted stock units. Our stock options and restricted stock units generally vest over a four-year period and our stock options have a term of ten years. We believe that these provisions encourage a long-term perspective and encourage key employees to remain with our company.

We account for equity compensation paid to all of our employees under the rules of ASC 718 Compensation — Stock Compensation, which requires us to estimate and record compensation expense over the service period of the award. All equity awards to our employees, including executive officers, and to our directors have been granted and reflected in our consolidated financial statements, based upon the applicable accounting guidance, at fair market value on the grant date. Generally, the granting of a non-qualified stock option to our executive officers is not a taxable event to those employees, provided, however, that the exercise of such stock option would result in taxable income to the optionee equal to the difference between the fair market value of the stock on the exercise date and the exercise price paid for such stock. Similarly, a restricted stock award subject to a vesting requirement is also not taxable to our executive officers unless such individual makes an election under section 83(b) of the Internal Revenue Code of 1986, as amended. In the absence of a section 83(b) election, the value of the restricted stock award becomes taxable to the recipient as the restrictions lapse.

Generally, a significant stock option grant is made within one month of when an executive officer commences employment. This grant is made within our guidelines for new-hire grants, consistent with the executive’s position. The guidelines were developed based on our historical practices and survey data. The size of each grant is set at a level that we believe is appropriate to create a meaningful opportunity for stock ownership based upon our company’s grant guidelines, the individual’s position with us and the individual’s potential for future responsibility and promotion. The relative weight given to each of these factors varies from individual to individual and all grants to executive officers are approved by the Compensation Committee.

Each executive officer’s performance during the prior year is measured as well as overall corporate performance when follow-on awards are granted. We generally grant follow-on equity awards on an annual basis. The terms of the award and the number of shares granted are established to ensure a meaningful incentive to remain an employee of our company. All equity awards under our LTIP are granted on the 10th business day of the calendar month in which the grant award is approved. There was one long-term equity incentive award granted to our executives during fiscal 2010. This grant occurred in December 2009 and was considered to be part of our fiscal 2011 long-term equity incentive award. Twenty-five percent of these long-term equity awards vest on April 1, 2011 and the remaining seventy-five percent vests in equal quarterly amounts thereafter through April 1, 2014. This vesting schedule aligns these long-term equity incentive compensation awards with the objective of being related to fiscal 2011. We anticipate that our next long-term equity incentive awards granted to our executives will be granted in October 2010, as we transition our annual long-term equity award grant program to a mid fiscal year grant and such awards will vest over four years in equal annual increments from the date of grant. As a result, we considered the long-term equity incentive awards granted in December 2009 to be partial year awards and the values ascribed to these awards were approximately 50% of a typical annual long-term equity incentive award as more fully described below.

In anticipation of this equity award granted in December 2009, we utilized the technology industry survey data described above in the “Peer Analysis of Executive Compensation” section to obtain comparable market data. The long-term equity incentive awards granted in December 2009 were granted with a value that was generally targeted against 50^th — 75^th percentile of the technology industry survey data obtained. This range was used because we have historically achieved revenue and earnings growth that is in the top tier of companies in our industry.

In determining the amount of the long-term equity incentive awards granted in December 2009, we reviewed the peer group survey data obtained related to both 1) an estimated value (in dollars) of the award and 2) an estimate percentage of the shares awarded as a percentage of the total common shares outstanding (including outstanding stock options and restricted stock units). Our compensation committee concluded that, with respect to the position of chief executive officer, the dollar value of a full equity award for the chief executive officer compensation should be approximately $2.0 million and approximately 0.4% of the common shares outstanding. As a result, the long-term equity award granted to our chief executive officer had a fair value of approximately $1.0 million and represented approximately 0.2% of the common shares outstanding after considering the 50% factor for a partial year award.

Our compensation committee determined that the aggregate economic value of long-term equity incentive compensation awarded to the executive officers contain a mix of non-qualified stock options and restricted stock units. Furthermore, long-term equity incentive awards granted to our executive officers are much more heavily weighted toward stock options because we believe that such awards align pay for performance by rewarding sustained achievement which drives long-term improvement of stockholder value. In addition, grants of restricted stock units allow us to offer equity compensation with fewer shares and less dilution to our stockholders, while simultaneously maintaining competitive rewards to retain our executive employee talent. As a result, the Compensation Committee allocated the value of Mr. Hammer’s long-term equity incentive award 75% to stock options and 25% to restricted stock units, which resulted in a grant of 84,154 stock options and 9,350 restricted stock units.

Using similar methodology, we awarded Messrs. Bunte, Miceli, Miiller and West with each a long-term equity incentive award with an estimated dollar value of approximately $0.8 million, $0.3 million, $0.4 million, and $0.3 million, respectively. The estimated value of Mr. Bunte’s equity award granted in December 2009 was allocated 75% to stock options and 25% to restricted stock units. The estimated value of Messrs. Miceli, Miiller and West equity award granted in December 2009 was allocated 60% to stock options and 40% to restricted stock units. As a result, Mr. Bunte was granted 64,167 stock options and 7,130 restricted stock units; Mr. Miceli was granted 18,177 stock options and 4,039 restricted stock units; Mr. Miiller was granted 23,731 stock options and 5,274 restricted stock units; and Mr. West was granted 16,326 stock options and 3,628 restricted stock units.

In addition to the long-term equity incentive award granted to each of our executive officers in December 2009, we also granted Mr. West an additional 15,000 stock options in July 2009. This award was a discretionary award based on the recent performance of Mr. West and vests over a four year period from July 2009 to July 2013.

We anticipate that we will continue to grant long-term equity incentive awards to each of our other executive officers on an annual basis at the discretion of the Compensation Committee. We have no program, plan or practice to coordinate award grants with the release of material non-public information. We anticipate that equity grants will generally occur in the third fiscal quarter. We believe that the resulting overlapping vesting schedule from awards made in prior years, together with the number of shares subject to each award, helps ensure a meaningful incentive to remain an employee and to enhance stockholder value over time.

Our executive officer’s participate in benefit programs that are substantially the same as all other eligible employees of our company.

We currently require our independent directors and our CEO to acquire an equity ownership interest in our common stock within five years of the date of our adoption of the policy (or five years from the date that they first became a director or CEO, as applicable) that, in the case of the independent directors is equal to five (5) times their base annual retainer, or in the case of our CEO is equal to five (5) times the CEO’s current annual base salary. The compensation committee is satisfied that this level of equity ownership among our independent directors and our CEO, and the equity ownership interests of our other directors and executive officers, is sufficient to provide motivation and to align these group’s interests with those of our shareholders.

The compensation committee has not adopted a policy with respect to whether we will make retroactive adjustments to any cash- or equity-based incentive compensation paid to executive officers (or others) where the payment was predicated upon the achievement of financial results that were subsequently the subject of a restatement. Our compensation committee believes that this issue is best addressed when the need actually arises and all of the facts regarding the restatement are known.

As part of its role, the Compensation Committee reviews and considers the deductibility of executive compensation under Section 162(m) of the Code which precludes our company from taking a tax deduction for individual compensation in excess of $1 million for our CEO and our four other highest-paid officers. This section also provides for certain exemptions to this limitation, specifically compensation that is performance-based within the meaning of Section 162(m) of the Code.

Our compensation philosophy and programs are designed to foster a performance-oriented culture that aligns our executive officers’ interests with those of our shareholders. The compensation committee also believes that the compensation of our executives is both appropriate and responsive to the goal of increasing revenue and profitability.

The following table summarizes the compensation earned by our Principal Executive Officer, Principal Financial Officer and the other three most highly paid executive officers whose total compensation exceeded $100,000. We refer to these individuals as our “named executive officers”:

None of our named executive officers participate in or have account balances in qualified or non-qualified defined benefit plans sponsored by us.

None of our named executive officers participate in or have account balances in non-qualified defined contribution plans maintained by us.

In February 2004, we entered into an employment agreement with N. Robert Hammer. The agreement has an initial term ending on March 31, 2005 and automatically extends for additional one-year terms unless either party elects, at least 30 days prior to the expiration of a term, to terminate the agreement. The agreement provides that Mr. Hammer’s annual salary shall be subject to annual review by our Board of Directors. The agreement also provides that Mr. Hammer shall be eligible for annual non-equity incentive plan compensation with a target bonus potential equal to a percentage of his base salary and that he shall be entitled to participate in the employee benefits plans in which our other executives may participate. If we terminate Mr. Hammer’s employment for any reason other than cause, death or upon a change in control of our company, the agreement provides that, for a one-year period, Mr. Hammer will be entitled to receive his then-current base salary (either in equal bi-weekly payments or a lump sum payment, at our discretion) and we will be required to continue paying the premiums for Mr. Hammer’s and his dependents’ health insurance coverage. In addition, Mr. Hammer will be entitled to any other amounts or benefits previously accrued under our then applicable employee benefit plans, incentive plans or programs. If we terminate Mr. Hammer’s employment by reason of death or disability, Mr. Hammer will be entitled to any compensation earned but not yet paid. The agreement provides that, during his term of employment with us and for a period of one year following any termination of employment with us, Mr. Hammer may not participate, directly or indirectly, in any capacity whatsoever, within the United States, in a business in competition with us, other than beneficial ownership of up to one percent of the outstanding stock of a publicly held company. In addition, Mr. Hammer may not solicit our employees or customers for a period of one year following any termination of his employment with us. Mr. Hammer’s employment agreement also contains a change in control provision which is discussed below in the section titled “Change in Control Agreements.”

Mr. Hammer has maintained his primary residence in the state of Florida since he began serving as our Chairman, President and Chief Executive Officer in 1998. Mr. Hammer’s position with us is his only full time employment. Mr. Hammer generally spends his time working for us in our office in Oceanport, New Jersey or traveling on business for us. He is generally in Oceanport when not traveling on business. As part of his annual compensation, we pay costs associated with Mr. Hammer’s travel between his residence in Florida and our headquarters in Oceanport, New Jersey and we also lease an apartment for Mr. Hammer’s use in New Jersey. See “Summary Compensation Table” for more information. The members of the Compensation Committee consider these costs in reviewing the annual compensation of Mr. Hammer. We do not believe that Mr. Hammer’s Florida residency has had a negative impact on the quality of his service to us or on his ability to meet his obligations as Chairman, President and Chief Executive Officer in the past and we do not anticipate that his Florida residency will have any negative impact on us in the future.

In February 2004, we entered into employment agreements with Alan G. Bunte and Louis F. Miceli. Each of these agreements has an initial term ending on March 31, 2005 and automatically extends for additional one-year terms unless either party to the agreement elects, at least 30 days prior to the expiration of a term, to terminate the agreement. The agreements with Messrs. Bunte and Miceli provide that the annual salary of each shall be subject to annual review by our chief executive officer or his designee, and also provides that each shall be eligible for annual non-equity incentive plan compensation with a target bonus potential equal to a percentage of the officer’s base salary. The agreements with Messrs. Bunte and Miceli each provide that these officers shall be entitled to participate in the employee benefits plans in which our other executives may participate. If we terminate the employment of either of these officers for any reason other than for cause or death, each of the agreements provide that, for a one-year period, the terminated officer will be entitled to receive his then-current base salary (either in equal bi-weekly payments or a lump sum payment, at our discretion) and we will be required to continue paying the premiums for the officer’s and his dependents’ health insurance coverage. In addition, the terminated officer will be entitled to any other amounts or benefits previously accrued under our then applicable employee benefit plans, incentive plans or programs. If we terminate Messrs. Bunte’s or Miceli’s employment by reason of death or disability, each executive officer will be entitled to any compensation earned but not yet paid. Each agreement provides that, during his term of employment with us and for a period of one year following any termination of employment with us, the officer may not participate, directly or indirectly, in any capacity whatsoever, within the United States, in a business in competition with us, other than beneficial ownership of up to one percent of the outstanding stock of a publicly held company. In addition, neither of these officers may solicit our employees or customers for a period of one year following any termination of employment with us.

Mr. Hammer’s employment agreement provides that if a change in control of our company occurs, all equity awards held by Mr. Hammer shall immediately become exercisable or vested. If a change in control of our company occurs and Mr. Hammer’s employment is terminated for reasons other than for cause (other than a termination resulting from a disability) within two years of the change in control, or if Mr. Hammer terminates his employment within 60 days of a material diminution in his salary or duties or the relocation of his employment within two years following a change in control of our company, then he shall be entitled to (1) a lump sum severance payment equal to one and a half times his base salary at the time of the change in control plus an amount equal to Mr. Hammer’s target bonus at the time of the change in control, and (2) health insurance coverage for Mr. Hammer and his dependents for an 18 month period.

We have entered into change of control agreements with all of our executive officers, other than Mr. Hammer, whose employment agreement sets forth the protections upon a change of control described above. Each of these agreements provide that if a change in control of our company occurs and the employment of any of the officers is terminated for reasons other than for cause, or if the officer terminates his employment within 60 days of a material diminution in his salary or duties or the relocation of his employment following a change in control of our company, then all equity awards held by the officer shall immediately become exercisable or vested. In addition, the change of control agreements with Messrs. Bunte and Miceli provide that if a change in control of our company occurs and the employment of either of these officers is terminated for reasons other than for cause within two years of the change in control, or if the officer terminates his employment within 60 days of a material diminution in his salary or duties or the relocation of his employment within two years following a change in control of our company, then the officer shall be entitled to (1) a lump sum severance payment equal to one and a half times the sum of the officer’s annual base salary at the time of the change in control and all bonus payments made to the officer during the one-year period preceding the date of the change in control, and (2) health insurance coverage for the officer and his dependents for an 18 month period. The change of control agreements with Messrs. Miiller and West have substantially identical provisions that provide for a lump sum severance payment equal to the officer’s annual base salary at the time of the change in control and health insurance coverage for the officer and his dependents for a 12 month period.

The change of control agreements with Messrs. Bunte and Miceli provide that, for an 18 month period following the termination of employment, the officers may not engage in, or have any interest in, or manage or operate any company or other business (whether as a director, officer, employee, partner, equity holder, consultant or otherwise) that engages in any business which then competes with any of our businesses, other than beneficial ownership of up to five percent of the outstanding voting stock of a publicly traded company. The agreements also prohibit Messrs. Bunte and Miceli from inducing any of our employees to terminate their employment with us or to become employed by any of our competitors during the 18 month period. Messrs. Miiller and West are subject to substantially identical non-competition and non-solicitation provisions for a one-year period following the termination of employment.

The amount of compensation and benefits payable to each named executive officer has been estimated in the table below. The amounts below assume that such termination was effective as of March 31, 2010, the last day of our fiscal year. The actual amounts to be paid out can only be determined at the time of such executive’s separation from us.

None of the named executive officers are eligible for compensation and benefits payable upon involuntary termination for cause or voluntary resignation or retirement and therefore such descriptions have been excluded from the table above. In addition, the amounts shown in the table above do not include payments and benefits to the extent they are provided on a non-discriminatory basis to salaried employees generally upon termination, such as any unreimbursed business expenses payable and distributions of plan balances under the CommVault Systems, Inc. 401(k) plan.

Our compensation committee of the board of directors determines the amount of any fees, whether payable in cash, shares of common stock or options to purchase common stock, and expense reimbursement that directors receive for attending meetings of the Board of Directors or committees of the Board of Directors.

In June 2009, our Compensation Committee engaged Radford to provide our Compensation Committee with an assessment of our non-employee director compensation and to provide peer analysis information for structuring our director compensation practices related to cash compensation, equity compensation and equity vesting. Radford provided compensation survey data from 18 technology industry companies. The list of companies included in the survey were Advent Software, Inc., Ariba, Inc., CSG Systems International, Inc., Dealer Track Holdings, Inc., Eclipsys Corp., Epicore Software Corp., I2 Technologies, Inc., Informatica Corp., Magma Design Automation, Inc., MSC Software Corp., Progress Software Corp., QAD, Inc., Radiant Systems, Inc., S1 Corp., SkillSoft Public Limited Co., SPSS, Inc., Websense, Inc., and Wind River Systems, Inc. The results of the Radford survey data and the subsequent recommendations were presented to the Compensation Committee as part of our fiscal 2010 executive compensation decisions for cash and equity compensation changes effective October 2009. Based on the Radford survey data we increased cash and equity compensation of our non-employee directors to be competitive against the 50^th percentile of the technology industry survey data obtained.

The fiscal 2010 cash compensation earned by non-employee directors for their services as members of the Board of Directors or any committee of the Board of Directors was as follows:

•

Annual retainer of $25,000 with an additional $2,000 for each board meeting attended;

•

The chairperson of our audit committee, compensation committee and governance committee received an additional annual retainer of $24,000, $7,500 and $7,500, respectively;

•

The lead director received an additional annual retainer of $7,500; and

•

Each committee member received an additional annual retainer of $5,000.

Each of the annual fees payable under this schedule was prorated to reflect the period from April 1, 2009 through June 30, 2009.

Subsequent to July 1, 2009

•

Annual retainer of $42,000 with an additional $2,000 for each board meeting attended;

•

The chairperson of our audit committee, compensation committee and governance committee receive an additional annual retainer of $30,000, $15,000 and $12,000, respectively;

•

The lead director receives an additional annual retainer of $20,000; and

•

Each committee member of the audit committee, compensation committee and governance committee receives an additional annual retainer of $15,000, $10,000 and $5,000, respectively.

Each of the annual fees payable under this schedule was prorated to reflect the period from July 1, 2009 through March 31, 2010.

Non-employee directors are also eligible to receive equity compensation under our LTIP and historically all equity awards to non-employee directors vested over a four year period. Based on the results of the Radford peer analysis discussed above, we modified our annual equity award grant practices to our non-employee directors during fiscal 2010 in that equity awards granted to non-employee directors will generally now cliff vest, with the entire award vesting one year from the date of grant. In fiscal 2010, we made two equity grants to our non-employee directors. The first grant occurred in August 2009 was for our fiscal 2010 grant. This equity grant in August 2009 included 7,500 non-qualified stock options and 4,000 restricted stock units to each non-employee director in which the entire award will cliff vest in August 2010. The second grant occurred in March 2010 and was for the first half of fiscal 2011 because we anticipate that our next equity incentive award grant to our non-employee directors will be in October 2010 consistent with our executives which is more fully described above in the “Long-Term Equity Incentive Awards” section. As a result, we considered the equity awards granted in March 2010 to our non-employee directors to be partial year awards and the value ascribed to the these awards was approximately 50% of a typical annual equity award. Therefore, the equity award granted to each non-employee director in March 2010 included 3,750 non-qualified stock options and 2,000 restricted stock units in which the entire award will cliff vest on September 30, 2010.

All future equity grants to our non-employee directors will be pursuant to our LTIP. See “Long-Term Equity Incentive Awards” above for more information about this plan. We also reimburse all of our directors for their reasonable expenses incurred in attending meetings of our board or committees.

The following table sets forth information concerning the compensation received for services rendered to us by our directors in fiscal 2010:

Compensation Policies and Practices as They Relate to Risk Management

We have reviewed our compensation policies and practices for all employees and concluded that any risks arising from our policies and practices are not reasonably likely to have a material adverse effect on us.

Employee Benefit Plans

1996 Stock Option Plan

We have reserved 11,705,000 shares of common stock for issuance under the 1996 Stock Option Plan. As of March 31, 2010, options to purchase 4,250,917 shares of common stock were outstanding at a weighted average exercise price of $5.95 per share, 6,904,309 shares had been issued upon the exercise of outstanding options and 549,775 shares remain available for future grants. The 1996 Stock Option Plan provides for the grant of nonqualified stock options and other types of awards to our directors, officers, employees and consultants, and is administered by our Compensation Committee.

The Compensation Committee determines the terms of options granted under the 1996 Stock Option Plan, including the number of shares subject to the grant, exercise price, term and exercisability, and has the authority to interpret the plan and the terms of the awards thereunder. The exercise price of stock options granted under the plan must be no less than the par value of our common stock, and payment of the exercise price may be made by cash or other consideration as determined by the Compensation Committee. Options granted under the plan may not have a term exceeding ten years, and generally vest over a four-year period. At any time after the grant of an option, the Compensation Committee may, in its sole discretion, accelerate the period during which the option vests.

Generally, no option may be transferred by its holder other than by will or the laws of descent and distribution or pursuant to a qualified domestic relations order as defined by the Internal Revenue Code or Title I of the Employment Retirement Income Security Act of 1974, as amended, or the rules thereunder. If an employee leaves our company or is terminated, then any options held by such employee generally may be terminated, and any unexercised portion of the employee’s options, whether or not vested, may be forfeited.

The number of shares of common stock authorized for issuance under the 1996 Stock Option Plan will be adjusted in the event of any dividend or other distribution, recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, liquidation, dissolution, or sale, transfer, exchange or other disposition or all or substantially all of the assets of our company, or exchange of common stock or other securities of our company, issuance of warrants or other rights to purchase common stock of our company, or other similar corporate transaction or event. In the event of the occurrence of any of these transactions or events, our Compensation Committee may adjust the number and kind of authorized shares of common stock under the plan, the number and kind of shares of common stock subject to outstanding options and the exercise price with respect to any option. Additionally, if any of these transactions or events occurs or any change in applicable laws, regulations or accounting principles is enacted, the Compensation Committee may purchase options from holders thereof or prohibit holders from exercising options. The Compensation Committee may also provide that, upon the occurrence of any of these events, options will be assumed by the successor or survivor corporation or be substituted by similar options, rights or awards covering the stock of the successor or survivor corporation.

The 1996 Stock Option Plan may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from time to time by our Board of Directors or our Compensation Committee. However, no action of our Compensation Committee or our Board of Directors that would require stockholder approval will be effective unless stockholder approval is obtained. No amendment, suspension or termination of the plan will, without the consent of the holder of options, alter or impair any rights or obligations under any options previously granted, unless the underlying option agreement expressly so provides. No options may be granted under the plan during any period of suspension or after its termination.

2006 Long-Term Stock Incentive Plan

On January 26, 2006, the Board of Directors authorized the created of the Long-Term Stock Incentive Plan (the “LTIP”). Upon the close of our initial public offering on September 26, 2006, we became eligible to grant awards under the LTIP. Under the LTIP, we may grant stock options, stock appreciation rights, shares of common stock and performance units to our employees, consultants, directors and others persons providing services to our company.

The maximum number of shares of our common stock that was initially allowed to be awarded under the LTIP was 4,000,000. On each April 1, the number of shares available for issuance under the LTIP is increased, if applicable, such that the total number of shares available for awards under the LTIP as of any April 1 is equal to 5% of the number of outstanding shares of our common stock on that April 1. As of March 31, 2010, there were 3,819,168 options to purchase shares of common stock outstanding at a weighted average exercise price of $15.32 per share and there were 1,010,917 shares of non-vested restricted stock awards outstanding. In addition, as of March 31, 2010, there were approximately 1,296,710 shares that remain available for future grants under the LTIP. The maximum number of shares that may be subject to incentive stock options shall be 25,000,000 over the life of the LTIP. The maximum number of shares that may be subject to options and stock appreciation rights granted to any one individual shall be 25,000,000 over the life of the LTIP. The maximum number of shares that may be subject to stock unit awards, performance share awards, restricted stock awards or restricted unit awards to any one individual that are intended to be performance based within the meaning of Section 162(m) of the Internal Revenue Code shall be 25,000,000 over the life of the LTIP (or $1,000,000 during any calendar year, if settled in cash.) The number of shares of common stock authorized for issuance under the LTIP will be adjusted in the event of any dividend or other distribution, recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, liquidation, dissolution, or sale, transfer, exchange or other disposition or all or substantially all of the assets of our company, or exchange of common stock or other securities of our company, issuance of warrants or other rights to purchase common stock of our company, or other similar corporate transaction or event.

Our Compensation Committee administers our LTIP. The LTIP essentially gives the Compensation Committee sole discretion and authority to select those persons to whom awards will be made, to designate the number of shares covered by each award, to establish vesting schedules and terms of each award, to specify all other terms of awards and to interpret the LTIP.

Options awarded under the LTIP may be either incentive stock options or nonqualified stock options, but incentive stock options may only be awarded to our employees. Incentive stock options are intended to satisfy the requirements of Section 422 of the Internal Revenue Code. Nonqualified stock options are not intended to satisfy Section 422 of the Internal Revenue Code. Stock appreciation rights may be granted in connection with options or as free-standing awards. Exercise of an option will result in the corresponding surrender of the attached stock appreciation right. The exercise price of an option or stock appreciation right must be at least equal to the par value of a share of common stock on the date of grant, and the exercise price of an incentive stock option must be at least equal to the fair market value of a share of common stock on the date of grant. Options and stock appreciation rights will be exercisable in accordance with the terms set by the Compensation Committee when granted and will expire on the date determined by the Compensation Committee, but in no event later than the tenth anniversary of the grant date. If a stock appreciation right is issued in connection with an option, the stock appreciation right will expire when the related option expires. Special rules and limitations apply to stock options which are intended to be incentive stock options.

Under the LTIP, our Compensation Committee may grant common stock to participants. In the discretion of the committee, stock issued pursuant to the LTIP may be subject to vesting or other restrictions. Participants may receive dividends relating to their shares issued pursuant to the LTIP, both before and after the common stock subject to an award is earned or vested.

The Compensation Committee may award participants stock units which entitle the participant to receive value, either in stock or in cash, as specified by the Compensation Committee, for the units at the end of a specified period, based on the satisfaction of certain other terms and conditions or at a future date, all to the extent provided under the award. A participant may be granted the right to receive dividend equivalents with respect to an award of stock units by the Compensation Committee. Our Compensation Committee establishes the number of units, the form and timing of settlement, the performance criteria or other vesting terms and other terms and conditions of the award at the time the award is made.

Unless our Compensation Committee determines otherwise, in the event of a change in control of our company that is a merger or consolidation where our company is the surviving corporation (other than a merger or consolidation where a majority of the outstanding shares of our stock are converted into securities of another entity or are exchanged for other consideration), all option awards under the LTIP will continue in effect and pertain and apply to the securities which a holder of the number of shares of our stock then subject to the option would have been entitled to receive. In the event of a change of control of our company where we dissolve or liquidate, or a merger or consolidation where we are not the surviving corporation or where a majority of the outstanding shares of our stock is converted into securities of another entity or are exchanged for other consideration, all option awards under the LTIP will terminate, and we will either (1) arrange for any corporation succeeding to our business or assets to issue participants replacement awards on such corporation’s stock, or (2) make any outstanding options granted under the plan fully exercisable at least 20 days before the change of control becomes effective.

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis contained in this proxy statement with management and, based on such review and discussion, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in our company’s annual report on Form 10-K for the year ended March 31, 2010 and in this proxy statement.

The Audit Committee comprises three directors and operates under a written charter for the Audit Committee. All of the members of the Audit Committee meet the definition of independent for purposes of the Nasdaq listing standards. In addition, our Board of Directors has determined that Mr. Walker qualifies as an “audit committee financial expert” under the applicable SEC rules and all of the members of Audit Committee satisfy Nasdaq’s financial literacy requirements.

The Audit Committee has furnished the following report:

The Audit Committee has reviewed and discussed the audited financial statements of our company for the fiscal year ended March 31, 2010 with our management. In addition, the Audit Committee has discussed with Ernst & Young LLP, our independent auditors (“Ernst & Young”), the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AU Section 380) as adopted by the PCAOB, “Communications with Audit Committees” and PCAOB Auditing Standard No. 2, “An Audit of Internal Control Over Financial Reporting Performed in Conjunction with an Audit of Financial Statements.”

The Audit Committee has also received the written disclosures and the letter from Ernst & Young required by PCAOB Ethics and Independence Rule 3526, “Communication with Audit Committees Concerning Independence,” and has discussed with Ernst & Young its independence from our company and our management.

The Audit Committee has considered whether the services rendered by our independent public accountants with respect to audit, audit-related, tax and other non-audit fees are compatible with maintaining their independence.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements for our company for the fiscal year ended March 31, 2010 be included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2010 for filing with the SEC.

Audit Committee

David F. Walker — Chairman
F. Robert Kurimsky
Daniel Pulver

Financial statements of our company and our consolidated subsidiaries will be included in our Annual Report furnished to all stockholders. The Audit Committee of the Board of Directors has appointed Ernst & Young LLP as independent public accountants for us to examine our consolidated financial statements for the fiscal year ending March 31, 2011, and has determined that it would be desirable to request that the stockholders ratify the appointment. You may vote for, vote against or abstain from voting with respect to this proposal. Assuming the presence of a quorum, the affirmative vote of a majority of the shares present, in person or by proxy, at the Annual Meeting and entitled to vote is required to ratify the appointment. If the stockholders do not ratify the appointment, the Audit Committee will reconsider the appointment for the 2012 fiscal year, rather than the 2011 fiscal year, because of the difficulty and expense involved in changing independent auditors on short notice. Ernst & Young LLP was engaged as our principal independent public accountants for fiscal years 1998 through 2010. Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting and are also expected to be available to respond to appropriate questions.

The following table summarizes the aggregate fees and expenses billed to us for the fiscal years ended March 31, 2010 and 2009 by our principal accounting firm, Ernst & Young LLP (“Ernst & Young”):

		2010				2009
		(In thousands)
Audit fees		$	1,052			$	1,073
Audit-related fees			42				13
Tax fees			374				294
All other fees			—				—
		$	1,468			$	1,380

Audit Fees — all services necessary to perform an audit of the consolidated financial statements of our company; the reviews of our company’s quarterly reports on Form 10-Q; services in connection with statutory and regulatory filings or engagements; comfort letters; statutory audits; consents and review of documents filed with the SEC, including documents relating to our initial public offering and follow-on public offering.

Audit Related Fees — consultation concerning financial accounting and reporting standards.

Tax Fees — tax compliance; tax planning; and other tax advice.

All Other Fees — any other work that is not Audit, Audit-Related or a Tax Service.

In considering the nature of the services provided by Ernst & Young, the Audit Committee determined that such services are compatible with the provision of independent audit services. The Audit Committee discussed these services with Ernst & Young and our management to determine that they are permitted under the rules and regulations concerning auditor independence promulgated by the SEC to implement the Sarbanes-Oxley Act of 2002, as well as by the American Institute of Certified Public Accountants.

The audit committee is responsible for appointing, setting compensation and overseeing the work of the independent auditor. The Audit Committee has established a policy regarding pre-approval of permissible non-audit services provided by the independent auditor. Generally, pre-approvals may be made by the chairperson of the Audit Committee in accordance with the rules of the Securities and Exchange Commission. All of the services performed by Ernst & Young in the year ended March 31, 2010 were pre-approved in accordance with the pre-approval policy adopted by the Audit Committee.

The Board of Directors is not aware of any other matters that may properly come before the Annual Meeting. However, should any such matters come before the Annual Meeting, it is the intention of the persons named in the enclosed form of proxy card to vote all proxies (unless otherwise directed by stockholders) in accordance with their judgment on such matters.

To the extent that this proxy statement is incorporated by reference in any other filing by us under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, the information included or incorporated in the sections of this proxy statement entitled “Executive Compensation — CommVault Systems, Inc. Compensation Committee Report on Executive Compensation” and “Report of Audit Committee” will not be deemed to be incorporated, unless specifically provided otherwise in such filing.

The cost of solicitation of Proxies will be borne by us. Solicitation will be made by mail, and may be made by directors, officers, and employees, personally or by telephone, telecopy or telegram. Proxy cards and material also will be distributed to beneficial owners of stock through brokers, custodians, nominees and other like parties, and we expect to reimburse such parties for their charges and expenses.

For a stockholder proposal to be considered by us for inclusion in our proxy statement and form of proxy relating to the annual meeting of stockholders to be held in 2011, the proposal must be received by March 11, 2011.

With respect to stockholder proposals not included in our company’s proxy statement and form of proxy, we may utilize discretionary authority conferred by proxy in voting on any such proposals if, among other situations, the stockholder does not give timely notice of the matter to us by the date determined under our By-laws for the submission of business by stockholders. This notice requirement and deadline are independent of the notice requirement and deadline described above for a stockholder proposal to be considered for inclusion in our proxy statement. Our Bylaws state that, to be timely, notice and certain related information must be received at the principal executive offices not later than the close of business on the 90th day prior to the first anniversary of the mailing of notice for the preceding year’s annual meeting. Therefore, to be timely under our Bylaws, a proposal for the 2011 annual meeting not included by or at the direction of the Board of Directors must be received no later than April 10, 2011.
