Arista, Fulcrum and Ixia Test 10-Gigabit Ethernet for Cloud Networking

Arista Networks, Fulcrum Microsystems and Ixia announced the results of collaborative performance and scalability testing of 10-Gigabit Ethernet in a cloud computing environment. The tests measured the performance of the Arista 7148SX 48-port 10GE SFP+ switch, which features Fulcrum's FocalPoint FM4224 switch silicon. The tests used full line-rate, large-scale traffic running fully meshed and yielded results that validated the switch's ability to provide the low-latency and throughput performance for lossless data center Ethernet transmission.


According to the companies, the test results showed "extraordinarily low latency" in the Arista switch -- as low as 600 nanoseconds (min) between any two ports -- and lossless performance for all frame sizes using IETF RFC 2544 and 2889 throughput test methodologies. This performance means scale-out environments can now get true non-blocking performance using the Arista 7148SX switches, as shown by the absence of packet drops in the RFC 2889 full-mesh test results.
