Mellanox Technologies and Arista Networks announced that IBM WebSphere MQ Low Latency Messaging maintained a latency of 4μs at rates up to 100K messages/second and 6μs at one million messages/second using Mellanox ConnectX-2 EN NICs with RoCE (RDMA over Converged Ethernet) and Arista 7100 10GigE switch. Latency remained consistently low as the number of multicast groups increased from one to one thousand.
RoCE is an add-on feature to Mellanox’s ConnectX-2 EN adapters that implements the IBTA RDMA over Converged Ethernet standard and utilizes the popular OpenFabrics Enterprise Distribution (OFED) and application programming interfaces (APIs). ConnectX-2 EN with RoCE supports both 10 and 40 Gigabit Ethernet today, making it the only Ethernet NIC future-proofed for 40 Gigabit Ethernet fabrics of the near future.
“ConnectX-2 EN with RoCE adapters deliver up to 1/10th the latency, reduced power consumption and improved economics compared to other standards-based 10GigE adapter solutions in the market today,” said John Monson, vice president of marketing at Mellanox Technologies. “The combination of low latency Ethernet switches from Arista and networking solutions from Mellanox provides financial services applications with leading low-latency and sustained performance that meet the financial market’s higher message rate requirements.”http://www.arista.com
