CommVault Systems, a leading provider of data and storage management solutions, today announced that CommVault QiNetix(TM) software is certified to manage data on the Windows Server 2003, Standard, Enterprise, and Datacenter Editions. CommVault QiNetix 4.2, which includes Galaxy, the Windows Centric enterprise-class data and storage management solution for heterogeneous environments, has demonstrated compliance with Microsoft's highest application development and testing standards.

Built and certified on the Microsoft Windows platform, CommVault Galaxy software provides comprehensive data protection that enables Windows Server 2003 customers to protect critical data and conduct stable business operations. CommVault's QiNetix unique migration capabilities can also assist customers in migrating data from older versions of Windows to Windows Server 2003.

"Microsoft once again welcomes CommVault Systems to the leading group of ISVs who have worked with Microsoft to provide the highest level of assurance to customers on Windows Server 2003, Standard, Enterprise, and Datacenter Editions," said Bob Ellsworth, Director of Windows Server Marketing, Microsoft Corporation. "By meeting the most stringent application testing criteria for Windows Server 2003 platforms, CommVault's QiNetix and Galaxy utilizes the new storage capabilities within Windows Server 2003. CommVault's software, built on Windows Server 2003, follows Microsoft's belief that Windows Server 2003 is the right platform in which to manage data in the heterogeneous enterprise."

As part of the requirement for receiving Windows Server 2003 certification, CommVault QiNetix software demonstrated stress-tested stability after it was installed and run on a 32-processor system. To ensure a high level of service for customers, CommVault Technical Support was tested to verify the company could provide round-the-clock support with the utmost quality and responsiveness. As part of the certification process, CommVault Galaxy software was installed and run on Microsoft Cluster Server and demonstrated that it could support failover to four cluster nodes.

"We are pleased to have completed the Windows Server 2003 certification process, after nearly two years of using CommVault and Windows Server 2003 in production environments at various locations." said Randy De Meno, Director of Advanced Applications and Microsoft Relationship for CommVault. "We're also excited about leveraging the new storage and granular application features built into Windows Server 2003. Our belief in Windows Centric Data Management has been substantiated by customers using Windows Server 2003 and our migration capabilities to better manage applications like Exchange, Active Directory and consolidation of Non-Windows data to Windows."

Built from the ground up and certified on the Windows platform, its centralized, easy-to-use, "all-in-one" solution offers cost-effective management and protection of enterprise-critical data.
