40Gb Ethernet – A Competitive Alternative to InfiniBand (White paper)

Chelsio

This paper supports this conclusion with three real application benchmarks running on IBM’s Rackswitch G8316, a 40Gb Ethernet aggregation switch, in conjunction with Chelsio Communications’ 40Gb Ethernet Unified Wire network adapter. This paper shows how iWARP offers comparable application level performance at 40Gbps with the latest InfiniBand FDR speeds.
