Architectural Guidance Includes CommVault Software -- the Backup and Restore Solution

CommVault(R) Systems Inc., an industry-leading provider of unified enterprise data management solutions, today announced their participation in the Microsoft System Architecture (MSA) for the Enterprise Data Center, which has a backup and restore solution.

Microsoft designed the Microsoft Systems Architecture (MSA) program to work with industry leading partners in the areas of enterprise data management, backup, restore, disaster recovery, networking, server hardware, storage and services to create complete enterprise data center architectures. The architectural guidance includes the deployment and operation of a backup and restore solution using CommVault(R) Galaxy(TM) software.

Microsoft, CommVault and the MSA partners strive to meet the performance requirements necessary to support today's rapidly evolving business needs. Each configuration is subject to a rigorous qualification process in order to ensure that the MSA standards are met and are consistent throughout all current and future MSA infrastructure offerings. CommVault participated with Microsoft and its partners in extensive testing and the development of deployment scenarios in order to ensure that customers using Windows-centric enterprise solutions can receive the technical expertise and guidance required in order to protect and keep their data highly available.

The guidance, available on Microsoft's TechNet web-site offers customers and IT architects the ability to plan, install and operate data centers that are resilient and have no single point of failure. The Windows Server platform guidance, blended into one data center solution, includes the Microsoft Windows 2000 Server family with Active Directory, SQL Server 2000 Enterprise Edition, and Exchange Server 2000, working with CommVault Galaxy software.

"Customers can be confident in their ability to design, build, manage, backup and restore proven and highly available systems based on the guidance in the Enterprise Data Center MSA that includes the CommVault Galaxy," said Jim Hebert, general manager, Windows Server Product Management Group. "The extensive contributions of our partners' many subject matter experts goes a long way toward assuring that Microsoft Systems Architecture is the right environment on which enterprises can run their mission-critical business applications."

"At CommVault, we're proud to partner with Microsoft on the MSA effort. We didn't just write documentation with Microsoft, we tested extreme environments and Disaster Recovery scenarios together for over a year. We jointly included heavy security, which included firewall protection, and then tuned our solutions for the best performance. The MSA effort shows CommVault's and Microsoft's products are enterprise-ready and we're glad to pass on this expertise to our joint customers. Windows is the right environment to support the enterprise, including heterogeneous enterprises," said Randy DeMeno, CommVault's Director of Advanced Applications and Microsoft Relationship.

The four chapters, covering System Design, Architecture, Operations and Daily Operations also contain important information about security, cost management and Return on Investment via backup and recovery. There are also many suggestions about:

-- Leveraging various media types for storage

-- How to take full advantage of SAN environments

-- Data retention and media rotation

-- Firewall and VLAN integration for secure environments

-- Recovering entire data centers, servers, applications and granular portions of applications.
