Network Appliance™ Enterprise-Class Storage Supports Riverbed® Wide-Area Data Services Solutions

San Francisco, Calif. - December 7, 2006 -- Riverbed Technology, Inc. (NASDAQ: RVBD) today announced a cooperative support agreement with Network Appliance, Inc. (NASDAQ: NTAP) to help customers protect their distributed data and take full advantage of heterogeneous data centers. The cooperative support processes for Riverbed's wide-area data services (WDS) solutions with NetApp® unified storage systems, NetApp NearStore® near-line storage systems, and NetApp V-Series virtualization systems help the two companies to better work with large enterprise customers to address customer challenges with the replication, backup, and consolidation of distributed data. Customers can now dramatically reduce the amount of data that is replicated from a corporate data center to a remote disaster recovery site with a NetApp and Riverbed solution, significantly improving recovery point objectives of a disaster recovery solution and minimizing data loss in case of disaster.

Riverbed's WDS solutions enable organizations with more than one office to overcome a host of severe problems, including poor application performance and insufficient bandwidth at remote sites. By speeding the performance of applications between distributed sites, Riverbed's award-winning Steelhead® WDS appliances enable companies to consolidate IT, improve backup and replication processes to provide data integrity, and improve staff productivity and collaboration. Steelhead appliances have been deployed in organizations ranging from the world's largest corporations with offices around the globe to small companies with a couple of sites that are just a few miles apart.

"This cooperative support agreement means that enterprise customers will benefit from enhanced protection of their distributed data," said Patrick Rogers, vice president of product and alliances at Network Appliance. "The combination of Riverbed's WDS solutions and NetApp enterprise-ready storage and data protection solutions help customers to improve remote replication and disaster recovery processes."

"The ability to replicate distributed data to a secure data center is a requirement for enterprises that have consolidated or plan to consolidate IT infrastructure," said Eric Wolford, senior vice president, marketing and business development at Riverbed. "The interoperability of Riverbed's WDS solutions and NetApp enterprise-ready storage and data protection solutions, combined with world-class support, will better equip enterprises with business continuity by speeding the replication and improving the management of distributed data."
