NetXen 10-Gigabit Linux Sockets Acceleration Sets New Bar for Network Performance, Ease of Deployment

Intelligent NIC Offers Industry's First Linux Socket Acceleration Solution That Requires No Modifications to the OS Kernel or Applications

SANTA CLARA, CA -- (MARKET WIRE) -- March 6, 2007 -- NetXen, Inc., the leader in multi-protocol 10-Gigabit Ethernet (10GbE) technology, today introduced Linux Sockets Acceleration™ (LSA), a solution that delivers far higher network performance while greatly reducing host CPU overhead. It is the first network acceleration solution for Linux that requires no modifications to the kernel, host TCP stack or applications, and can offload both user- and kernel-mode applications. NetXen's LSA is also the first solution to support NIC and offload modes simultaneously.

The new Linux offload solution follows a Microsoft Chimney solution previously announced by NetXen. With these products, NetXen is the only vendor to provide stateful network acceleration for both Windows and Linux. Stateful functions represent 70 to 80 percent of the network processing workload, yet competing solutions do not handle these functions. Now for the first time, NetXen gives IT departments a single solution that dramatically improves network performance for both Linux and Windows machines.

NetXen's Intelligent NIC™ delivers these unique advantages by providing a complete set of 10GbE acceleration capabilities on the NIC. These capabilities cover not only the datapath, but connection set-up and teardown, connection state management, and error handling. This socket-level acceleration allows users to take advantage of the OS stack bypass without recompiling the Linux kernel or modifying applications. Simply by plugging in the card and loading drivers, users nearly double network performance for 1500-byte packets while decreasing CPU utilization by a factor of two.

In addition to providing full socket-level acceleration, the LSA solution allows users to run NIC and TCP modes simultaneously with NetXen's Selective Acceleration™ technology. With Selective Acceleration, any specialized applications that benefit from using host-based protocols can continue to do so under user control.

"IT departments demand consistent networking features and functions across OS platforms in heterogeneous environments," said Sanjeev Jorapur, vice president of technology at NetXen. "By providing complete, stateful network acceleration for both Linux and Windows, we're helping IT managers to easily maintain cross-platform consistency in features and transparency in virtualized environments. This is an important capability for next-generation datacenters."

"The HP BladeSystem c-Class design featuring the industry-breakthrough Virtual Connect technology provides wire-once simplicity for data centers," said Dwight Barron, chief technologist, BladeSystem Division, HP. "NetXen's intelligent 10-Gigabit network for Linux and Windows is consistent with our vision of converged Ethernet fabrics that are simple to deploy and manage."

"The NetXen solution measurably improves network throughput and processor efficiency without requiring changes to the system, stack or applications. Additionally, because the solution is programmable, it can evolve to keep up with changes in networking technology," said Dr. Steven Hunter, chief technology officer of IBM BladeCenter. "This is a key technology breakthrough which will help drive mainstream adoption of 10GbE and advanced offloads in the future."

"NetXen's Linux Loadable Kernel Module is the only way to get this done for real production environments," said Jeffrey M. Birnbaum, CEO of 60East Technologies and former managing director, global head of enterprise computing, and chief technology architect in Morgan Stanley's Institutional Securities Division. "This is an elegant solution for Linux network acceleration, and NetXen has taken major strides toward the emerging paradigm of 10GbE high-bandwidth, low-latency networking combined with multicore computing unburdened by TCP processing. The NetXen solution is the first to bring balance to the division of labor between compute and network."
