Business Wire, June 26, 2006

CAMPBELL, Calif. -- Silverback Systems, Inc., the leader in advanced Ethernet-acceleration technologies, today announced it is teaming with the StoreVault division of Network Appliance, Inc. (NASDAQ:NTAP) to offer Silverback's iSNAP(R) 2110 dual-port iSCSI host bust adapter (HBA) as an option for the new StoreVault(TM) S500 network storage system for the small and medium business (SMB) market. When used in a host computer connected to the StoreVault S500, which NetApp introduced today (www.netapp.com/news), the iSNAP 2110 HBA offloads several tasks that a host connected to the StoreVault S500 would otherwise need to manage, including iSCSI and TCP/IP protocols, enabling SMB customers to take advantage of unprecedented network storage acceleration provided by the patented iSNAP technology.

"With Silverback Systems and Network Appliance teaming to provide iSCSI acceleration technology to the SMB market, the two companies are advancing the delivery of mission-critical performance and reliability at economical prices," said Harry Petty, vice president of marketing and business development at Silverback Systems. "Small and medium businesses now can afford best-of-class iSCSI connectivity while providing application servers with performance headroom."

First All-in-One Storage Solution for SMB Meets First Cost-Effective Enterprise-Class HBA

The StoreVault S500 is the industry's first scalable all-in-one network storage appliance for the SMB market segment supporting network attached storage (NAS), iSCSI storage area network (SAN), and Fibre Channel SAN, providing SMB customers unparalleled flexibility for their network storage environments.

The iSNAP 2110 iSCSI HBA is the industry's first enterprise-class storage adapter at an entry-class price point. Capable of delivering up to 400MB/s throughput and 60K server IOPS (iSCSI I/Os per second), it outperforms competitive offerings in IOPS, throughput, and CPU utilization and is priced up to 30 percent lower than current alternatives. The iSNAP 2110 includes dual Ethernet ports and initiator support for Windows(R) Server 2003, Redhat Linux(R), and SUSE Linux.

Architected for Acceleration

Silverback's iSNAP technology is architected for acceleration. Silverback HBA products based on iSNAP technology accelerate the performance of servers, iSCSI storage devices, NAS appliances, blade servers, and multi-protocol storage routers while providing flexibility, scalability, resiliency, and high availability under the most extreme OLTP traffic conditions. The iSNAP technology dramatically speeds access to IP storage in a variety of different configurations by offloading both networking and upper-layer protocols such as iSCSI.
