Woven Systems Inc, the leading innovator of Ethernet Fabric switching solutions for data centers and high-performance computing clusters announced that Sandia National Laboratories, a multiprogram laboratory operated by Lockheed Martin for the U.S. Department of Energy, is deploying the EFX 1000 Ethernet Fabric Switch in a 128-node compute cluster.
Sandia chose the EFX 1000 based on its proven ability to sustain 10 Gbps Ethernet throughput in a large remote direct memory access (RDMA) cluster during exhaustive testing at its Livermore, California laboratory. (Editor's Note: See Woven press release dated August 7, 2007, on "Woven Systems and Chelsio Communications Deliver Scalable High Performance for Computing Clusters at Sandia National Laboratories" for details on Sandia's evaluation.
"The ability to deploy standard 10 Gigabit-per-second Ethernet in compute clusters is a breakthrough advance for the industry," said John Naegle, senior engineer with Sandia. "Adaptive routing in an Ethernet mesh fabric, like Woven's, dynamically and automatically changes paths to eliminate congestion and balance traffic flows. This is particularly critical in a compute cluster where the application traffic patterns are changing constantly."
The Ethernet Fabric utilizes Woven's Active Congestion Management technology with latency-minimizing routing algorithms to balance traffic flow across the mesh fabric and deliver unprecedented levels of performance. The technology also detects switch or link failures, and automatically re-routes traffic to an alternate path in less than 10 ms, providing resiliency with no lost network connections and time outs.
