Bangalore, October 18, 2007 — CommVault® (NASD: CVLT) today announced that it has added the Simpana™ 7.0 software suite of products to its OEM agreement with Hitachi Data Systems Corporation, a wholly-owned subsidiary of Hitachi, Ltd. (NYSE: HIT), for CommVault’s industry-leading data protection software suite, CommVault Simpana™ 7.0.

Today's news marks an extension to the existing worldwide OEM agreement the companies forged in March, 2005.

Commenting on today’s announcement, John Mansfield, senior vice president, Global Solutions Strategy and Development, Hitachi Data Systems said, “Building on the worldwide success of our partnership with CommVault, we are delivering an integrated solution that represents the combined synergies of Hitachi’s industry-leading storage systems and CommVault’s sophisticated data protection software. The Hitachi Data Protection Suite 7.0 enables enterprise customers to securely store, manage and retrieve their business-critical data, and ensures that valuable resources are focused on the business rather than managing storage environments.”

Regulatory compliance and mitigating exposure to risk are two of the most pressing requirements facing IT organizations today. The Hitachi Data Protection Suite 7.0 offers several advanced capabilities to align with these important business priorities including smart client back-up, enterprise-wide search and discovery, single instance store (SIS), high-performance content indexing, data classification, expanded security and advanced encryption features. Unlike competitive point products, the Hitachi Data Protection Suite 7.0 is a truly integrated software solution that enables customers to gain greater visibility across their entire storage environment, including backup, archive and online data assets, which vastly improves storage utilization, service level agreements, and risk management.

Leveraging the advanced functionality of Hitachi storage systems, the Hitachi Data Protection Suite 7.0 benefits customers by delivering snapshot-assisted backup, snapshot management and rapid data movement, which improves data availability while also dramatically lowering management expenditures.

“CommVault’s Simpana 7.0 software suite is a bold step forward in helping transform the way users access, leverage and interact with corporate data,” said David West, CommVault’s vice president of business development and marketing. “With the new features and disk-based enhancements in CommVault Simpana, Hitachi Data Protection Suite 7.0 can help IT professionals address the issues behind the growing cost and complexity of their storage environments. Our relationship with Hitachi Data Systems allows us to jointly expand our leadership in this market.”

As a leading provider of systems and software solutions targeting patient safety and operational efficiency in healthcare facilities, Omnicell, Inc. (NASDAQ: OMCL) utilizes the Hitachi Data Protection Suite 7.0 to protect and manage its data stored on Hitachi storage systems.

“Our goal is to streamline access to our corporate data and provide consistency, security and high levels of reliability while maximizing our IT resources and budget,” said Jorge Taborga, vice president and CIO, Omnicell. “Hitachi Data Protection Suite 7.0 will continue to help us improve the availability of our data.”
