NetXen Begins Shipping 10 Gigabit iWARP RDMA Solution

Availability of Low Latency, High Performance RDMA-Enabled 10 Gigabit Ethernet Adapters Featured at Interop

LAS VEGAS, NV--(Marketwire - April 29, 2008) - Interop -- NetXen, Inc., a leading provider of breakthrough 10-Gigabit Ethernet (10GbE) technology and products, today announced the general availability of RDMA-enabled 10GbE solutions. The iWARP RDMA solution is being offered as a firmware upgrade to NetXen Intelligent NIC® products. The iWARP stack runs on the NXB-10GCX4 Intelligent NIC, a low-profile 10 Gigabit Ethernet PCI Express card with native CX4 copper interface. Demonstrations of the solution will be presented during Interop at NetXen Booth #2731, April 29 to May 1, 2008.

The NetXen RDMA-enabled adapter is an extremely cost-effective, low-latency 10GbE product that is ideally suited for high-performance computing and clustering applications. It supports uDAPL (User Direct Access Programming Library) and popular MPI (Message Passing Interface) implementations and is OpenFabrics Enterprise Distribution (OFED) compliant. Support for the OFED software stack is already integrated into major versions of Linux distributions from Novell and Red Hat, making NetXen's RDMA implementation a "plug-and-play" solution for Linux users.

Simultaneous support of high-performance NIC and RDMA modes enables a unified fabric in the datacenter, simplifying deployment and management. Additionally, the programmability of the Intelligent NIC allows changes to protocols and APIs to be implemented in firmware, without the need for expensive hardware upgrades.

"In today's HPCC environments there are typically two to three fabrics. NetXen's iWARP-enabled Intelligent NICs now give datacenter managers the ability to run network traffic, storage traffic and IPC traffic over a single Ethernet fabric. Ethernet remains the dominant fabric in HPCC; iWARP extends the range of applications for which Ethernet is suited, and reduces overall cost of acquisition, deployment and management," said Vikram Karvat, senior director of marketing at NetXen.

NetXen's iWARP RDMA solution achieves results on par with InfiniBand DDR on applications such as LS-Dyna as well as storage benchmarks such as Luster. On LS-Dyna test cases, wall clock times are within 1-2% of InfiniBand and as much as 60% better than TCP over Ethernet. Thus, datacenter managers get the advantages of using a standard Ethernet infrastructure, and don't have to configure a complicated fabric, while obtaining a higher level of performance than was previously possible on Ethernet.

More information about NetXen's 10 Gigabit Ethernet Intelligent NIC adapters and RDMA support can be found at NetXen's RDMA solution will be highlighted at Interop 2008, in booth #2731.
