Santa Clara: Leaders in multi-protocol 10-gigabit Ethernet technology, NetXen, launched Linux Sockets Acceleration, a higher network performance solution that greatly reduces 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. The Linux offload solution follows a Microsoft Chimney method.
NetXen provides a complete set of 10GbE acceleration capabilities on the NIC. These capabilities cover not only the data path, 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.
"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 data centers."
"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 and former Thus, making NetXen the only vendor to provide 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.
