Adaptec Showcases TCP/IP Offload Network Interface Card at WinHEC

5/9/2003 - Adaptec, Inc. (NASDAQ:ADPT), the global leader in storage infrastructure solutions, teamed with Microsoft at WinHEC 2003 for a technology demonstration of Adaptec's TCP/IP offload network interface card (NIC) working with Microsoft's new TCP/IP Offload Architecture.

"Microsoft is working closely with Adaptec to demonstrate the ability of TCP/IP Offload Engines to significantly reduce host CPU demands associated with multi-gigabit networking," said Jawad Khaki, corporate vice president, Windows Networking & Communications Group at Microsoft. "Adaptec's efforts in this area have been very helpful in enabling us to prove the capability and value of this technology."

Adaptec and Microsoft demonstrated Adaptec's TCP/IP offload-enabled NIC running on Microsoft's Chimney Offload Architecture, highlighting the offload engine's ability to maximize the performance of network-intensive applications such as file serving, backup, and network attached storage. Adaptec's TOE technology offloads TCP/IP processing from the host to the accelerator card to reduce CPU utilization and make additional processing power available for networked applications.

Original equipment manufacturers are increasingly turning to TCP/IP offload as a way to improve application performance for their customers.

"The Microsoft-Adaptec demonstration at WinHEC is a key step toward helping Microsoft customers accelerate their network-intensive applications such as LAN-based backup, file serving over Ethernet and IP storage," said John Hufferd, senior technical staff member with IBM's System Group.

"Adaptec is pleased to be working with Microsoft to spearhead the industry transition to network acceleration solutions using TCP/IP offload," said Ram Jayam, vice president and general manager of Adaptec's Storage Networking Group. "Our joint development work has culminated in a standard TOE implementation that will help enterprises and small businesses accelerate the performance of networked applications and cost-effectively extend the performance of their servers."

TCP/IP Offload and Network Applications Performance
More organizations are deploying Gigabit Ethernet to enable IP storage networking and increase the performance of file serving, video editing, CAD/CAM, and other bandwidth-intensive applications. In the process, host CPUs have become the bottleneck in reaching Gigabit Ethernet line rates as they split time between processing TCP/IP commands and network applications. Traditionally, this is resolved by adding new servers to increase processing capacity. For a significantly smaller investment, TOE technology solves the CPU bottleneck by offloading network processing onto the NIC. This frees CPU capacity for application processing.

"We expect Adaptec's TOE technology, running under Microsoft's Chimney Architecture, to speed the adoption of iSCSI storage solutions, bringing all the value of the block storage network to the entire corporate server pool, not just the most visible ones," said Steve Duplessie, senior analyst, Enterprise Storage Group.
