XIOTECH AND COMMVAULT OFFER CONTINUOUS OPERATIONS FOR MICROSOFT EXCHANGE ENVIRONMENTS; FAST RESTORE FOR EXCHANGE DELIVERS INDUSTRY'S FASTEST TIME TO RECOVERY

XIOtech Corporation, a storage networking innovator, and CommVault(R) Systems, Inc., a provider of unified enterprise data management solutions, today announced the availability of their Fast Restore for Exchange solution for Microsoft(R) environments, fully taking advantage off the new storage and shadow management features of Exchange Server 2003 and Windows(R) Server 2003. Fast Restore for Exchange combines industry leading time-to-recovery and the dynamic simplicity of Magnitude 3D(TM) with the intelligent archiving and quick recovery of QiNetix(TM) to deliver the next level of continuous operations for Exchange environments.

The ability to backup data securely and recover it quickly is increasingly important for enterprises struggling to meet customer demands and comply with increasing government regulations. Furthermore, enterprises must manage Exchange data more granularly and for longer periods of time due to compliance regulations. Fast Restore for Exchange empowers enterprises to meet these challenges through Intelligent Archiving, which gives organizations the ability to recover even the smallest, most obscure, pieces of data and Dynamic Virtual Linking, which enables organizations to recover data from remote locations in a matter of minutes instead of the hours or days required by competing solutions. Together, these capabilities deliver near-immediate return to operations for business operations.

Included in the combined offering from XIOtech(R) and CommVault is the ability to track, archive and store every message in and out of an Exchange server and the capability to recover information based on content from messages or attachments within the message.

Fast Restore for Exchange is specifically designed to span the needs of enterprise Windows environments, accelerating migration from Windows NT(R) Server 4.0, Windows 2000 and older versions of Exchange. Organizations can deploy Fast Restore for Exchange today with QiNetix, insuring older Windows and Exchange data can be restored to the snapshot and Shadow Management ready features built into Exchange Server 2003 and Windows Server 2003. This solution fully leverages the storage infrastructure features such as shadow copy via Microsoft's Volume Shadow Copy Service (VSS), which is built into Exchange Server 2003 and Windows Server 2003. Fast Restore for Exchange also applies the proven benefits of Magnitude 3D's dynamic simplicity within a resilient, scalable enterprise architecture, simplifying deployment and ongoing management of Exchange server and storage infrastructures.

"Backup and restore capabilities are vitally important to our customers," said Keith McCall, director of Exchange Solutions at Microsoft. "We are happy to see industry partners such as XIOTech and CommVault provide our mutual customers with new backup and restore solutions for Exchange."

"We are committed to working with Microsoft, CommVault and CompuCom to develop innovative storage solutions for the Microsoft customer base," said Alain Andreoli, CEO of XIOtech. "Magnitude 3D's dynamic simplicity and enterprise architecture are the perfect complement to Microsoft's customer requirements, blending dramatically reduced TCO with next generation storage capability. Our solutions fundamentally alter what Microsoft-driven organizations should expect from their SANs - enabling these environments to affordably deploy enterprise SAN capabilities that are easily managed by an IT generalist."

"Recovery of critical applications like Exchange must help meet the uptime demands of customer environments. The joint CommVault, XIOtech Fast Restore for Exchange solution gives them the responsiveness and performance they require," said Bob Hammer, chairman and CEO, CommVault Systems. "Flexible and innovative recovery solutions that offer customers a wide range of options letting them tailor the recovery to the size of the loss ensures IT can meet their service levels."

Fast Restore for Exchange will be available in the first quarter of 2004 and will be shipped, installed and integrated into customer environments by joint partners of Xiotech and CommVault. CompuCom Systems Inc., a national leader in helping companies plan, implement and manage multi-vendor, industry-standard computing environments is one example of such a company. Fast Restore for Exchange is the second Dimensional Solution launched by XIOtech. Dimensional Solutions are application-driven bundles that are built around Magnitude 3D's next-generation enterprise storage architecture, leveraging its dynamic simplicity, unmatched flexibility and scale to deliver dramatic reductions in the cost of storage and operations.
