Sunnyvale, Calif. - December 12, 2007 -- Riverbed Technology, Inc. (NASDAQ: RVBD), the technology and market leader in wide-area data services (WDS), and NetApp (NASDAQ: NTAP) today announced dramatic performance results that show Riverbed's Steelhead® WDS appliances accelerate customer WAN performance of NetApp® ReplicatorX™ software while reducing WAN bandwidth. Through testing, the companies found that with Steelhead appliances, an initial replication operation performed by ReplicatorX finished 66 times faster with a 98% decrease in bandwidth utilization. In addition, subsequent incremental replication operations ran 75 times faster.

The results demonstrate that NetApp and Riverbed® provide enterprise customers with proven, high-performance data replication solutions to meet their most stringent recovery point objectives (RPOs) while reducing their networking infrastructure costs. Together, the two companies are providing enterprises with a solution to build robust disaster recovery plans and provide resiliency of mission-critical corporate data, including enterprise resource planning (ERP); online transaction processing (OLTP); and financial, legal, and medical records, in both the data center and remote data centers.

The Double-Edged-Sword Challenge
Customers typically face two challenges when assessing their replication needs. The first is managing data replication and recovery across heterogeneous infrastructures while avoiding added complexity. NetApp ReplicatorX helps customers to cost-effectively and easily replicate block data across any vendor's storage architecture (Fibre Channel SAN, IP SAN, DAS, or internal disk) that may be attached to any server (Windows®, UNIX®, Linux®, or virtual machines). ReplicatorX also replicates data across any distance using an existing IP network. The NetApp replication solution reduces management complexity and provides cost-effective, tiered disaster recovery, enabling rapid recovery of an up-to-the-second replica of production data. ReplicatorX can also replicate production data from any vendor's storage system to a NetApp storage system for rapid, cost-effective creation of clones for application development and testing with NetApp FlexClone® technology. Customers can also reduce the downtime and disruption typically associated with data migration projects across heterogeneous infrastructures using ReplicatorX.

The second challenge is meeting stringent recovery point objectives for mission-critical applications without significantly increasing network infrastructure costs, as well as insufficient bandwidth at remote sites. Riverbed WDS solutions add value by improving replication performance between data centers and remote offices up to 100 times. Riverbed's award-winning Steelhead WDS products enable companies to consolidate IT, improve backup and replication processes to ensure data integrity, and improve staff productivity and collaboration.

The power behind the WDS solutions is the Riverbed Optimization System (RiOS™), which accelerates applications and data through a combination of data reduction, TCP optimization, and application-level protocol optimizations. RiOS provides data streamlining, transport streamlining, application streamlining, and management streamlining, eliminating up to 98% of a company's replication traffic on the WAN. These technologies, along with RiOS management capabilities, provide a comprehensive solution for enterprise WDS.

"NetApp and Riverbed are delivering to customers a solution that reduces data loss exposure to help get their businesses back up and running with minimal loss in productivity, should an event impacting their production infrastructure occur," said Eric Wolford, senior vice president, Marketing and Business Development at Riverbed.

"NetApp is pleased to continue working closely with Riverbed to provide a comprehensive replication and recovery solution and help enterprises meet their most stringent business continuity service level agreements within limited budgets," said Yoram Novick, vice president and general manager of the Data Replication business unit at NetApp.
