Cloud computing is placing increasingly stringent demands on datacenter networks. Applications like MapReduce and Hadoop demand high bisection bandwidth to support their all-to-all shuffle communication phases. Conversely, Web services often rely on deep chains of relatively lightweight RPCs. While HPC vendors market niche hardware solutions, current approaches to providing high-bandwidth and low-latency communication in the datacenter exhibit significant inefficiencies on commodity Ethernet hardware.
