Arrow ECS, Riverbed Sign Distribution Agreement

Arrow Enterprise Computing Solutions, a business segment of Arrow Electronics Inc. [NYSE: ARW], and Riverbed™ Technology [NASDAQ: RVBD], the information technology infrastructure performance company for networks, applications and storage, have signed a North American distribution agreement.

Riverbed® wide-area network optimization solutions help to improve remote and mobile employee productivity, enable private clouds, and provide enterprise-wide network and application visibility, while eliminating the need to increase bandwidth, storage or servers.  By speeding the performance of applications between remote offices, private data centers and mobile workers, in some cases by up to 100 times, Riverbed WAN-optimization solutions enable companies to consolidate IT, improve backup and replication processes to ensure data integrity, and improve staff productivity and collaboration.

"Riverbed WAN-optimization solutions allow our resellers to reduce their customers' capital and operating expenditures by eliminating remote server maintenance costs through the consolidation and virtualization of centralized and distributed application access," said William Botti, president and chief operating officer of Arrow ECS' Alternative Technology group. "Accelerating performance and improving user productivity while reducing cost is a significant value proposition for resellers."

"Arrow ECS brings significant channel and market presence in the network management arena.  We are confident that the combination of our world-class products and Arrow ECS' ability to bring solutions to market will maximize the North American market opportunity," said Dave M. Peranich, senior vice president of worldwide sales at Riverbed.

Products under the agreement include:

• Riverbed Steelhead® appliances and Steelhead Mobile for large, midsize and small offices, data centers and mobile clients;

• The Riverbed Services Platform, a virtualized platform within the Steelhead appliances that provides customers with the capability to run up to five additional local branch office services and applications, eliminating the need to deploy and maintain full-blown servers;

• The Central Management Console and Interceptor® appliance, helping to manage and scale Steelhead appliance deployments; and

• Cascade™ appliances, which are used for advanced network and application performance analysis and reporting.
