-- CommVault QiNetix 6.1 SRM for Heterogeneous Environments Provides Simplified Storage Management, Improved Application and File System Analysis of Primary Storage --

Oceanport, NJ — June 14, 2006 — CommVault®, a provider of Unified Data Management™ solutions, today announced the availability of QiNetix StorageManager (QSM), Version 6.1 software with support for Microsoft SharePoint Products and Technologies. This solution helps administrators monitor data growth, manage resource utilization and reduce costs in environments that would traditionally rely on manual collection and analysis of data from disparate data sources. QSM 6.1 improves the management of application and file system data in primary storage for heterogeneous storage environments, including installations running Novell NetWare, Microsoft Windows, Linux and UNIX.

QSM, a component of the QiNetix 6.1 Unified Data Management suite, is an application-aware SRM solution that provides simplified resource monitoring and management for heterogeneous storage environments. As an entry point to the QiNetix 6.1 suite, or as a hardware-independent stand-alone SRM tool, QSM 6.1 simplifies analysis of primary storage utilization for enterprise applications and file systems.

For administrators seeking to improve storage availability and capacity management, QSM provides file system-level resource management of Windows Server environments, NetWare, Linux, UNIX and NAS volumes, and application-level management of Microsoft Exchange Server, Microsoft SharePoint Technologies, Microsoft SQL Server and Oracle databases. Users with high disk utilization can easily identify files for deletion or migration to secondary storage. Users experiencing server downtime will benefit from automated alert notification. Storage managers can use QSM to gain visibility into historical storage use and future trends, improve budgeting, monitor resource utilization, institute chargebacks and identify storage assets for reclamation.

QSM 6.1 Storage Resource Management allows administrators to:

• Identify the location and owner of old, large, and prohibited file types
• Improve budgeting and resource utilization by improved understanding of where data resides and the underlying cost of managing that data
• Accurately forecast and provision storage by projecting future requirements
• Identify stale and untouched data for migration to secondary storage
• Monitor storage growth trends by resource and application
• Reclaim underutilized storage resources

"Knowing what type of data resides in heterogeneous file systems, databases and applications such as Microsoft SharePoint Portal Server and Windows SharePoint Services is the first step to reliably managing and protecting that data," said Dave West, vice president, marketing and business development, CommVault. "QSM 6.1 helps storage, database and application specific administration teams understand which data resides where, who owns it, and the true cost of managing that data. It's a powerful monitoring tool and especially useful for managing the many data types contained in a growing SharePoint environment. CommVault QSM 6.1 assists administrators in tracking documents, events, growth and other critical SharePoint data, as well as providing a full-featured management tool for those who have been looking for a simple, easy-to-use, and powerful SRM solution."

With the SharePoint platform used as the foundation application for various data types, CommVault's QSM is an excellent infrastructure management tool for administrators implementing Microsoft SharePoint Products and Technologies across Windows Server environments," said Robert Bernard, general manager of the Global ISV Group at Microsoft Corp. "Together with CommVault, we are enabling our mutual customers to reduce costs, manage resource utilization and allow for greater innovation within their businesses by adding easy-to–use, powerful features to SharePoint Products and Technologies."
