News from EETimes points towards a startup that claims to offer an extreme performance advantage over Infiniband. A3Cube Inc. has developed a variation of the PCIe Express on a Network Interface Card to offer lower latency. The company is promoting their Ronniee Express technology via a PCIe 2.0 driven FPGA to offer sub-microsecond latency across a 128 server cluster. In the Sockperf benchmark, numbers from A3Cube put performance at around 7x that of Infiniband and PCIe 3.0 x8, and thus claim that the approach beats the top alternatives. The PCIe support of the device at the physical layer enables quality-of-service features, and A3Cube claim the fabric enables a cluster of 10000 nodes to be represented in a single image without congestion. The aim...
