Chelsio Communications announced the availability of a specialized T420 Low Latency (LL) server adapter that delivers iWARP RDMA connectivity with the shortest delay available in a network interface card. The T420-LL-CR has been extensively tested and found to deliver raw Ethernet queue pair latency of 3.0 microns, user mode UDP latency of 3.2 microns, RDMA verbs latency of 3.4 microns and MPI latency of 3.7 microns.

"HPC cluster architectures are moving away from proprietary and expensive networking technologies towards Ethernet and the performance gains and value proposition of TCP/IP continues to lead the way," said Kianoosh Naghshineh, president and CEO of Chelsio. "The LL version of our popular T420 card demonstrates the linear scalability of the T4 ASIC, which is essential to ensure continuous low latency operation for the high demand applications in HPC and financial applications."
