RDMA (Remote Direct Memory Access) and its RoCE (RDMA over Converged Ethernet) implementation, currently available in FreeBSD, is growing in popularity as a way to transfer large amounts of data with high bandwidth, low latency and minimal CPU involvement. This session will describe the RDMA stack update done in FreeBSD, focusing on the addition of RoCEv2 (Routable RoCE) and complementary protocols. We will also present the performance benefits of RDMA, demonstrating the enhancement of several storage protocols relaying on RoCE transport, starting with what is already part of FreeBSD – iSER, an iSCSI extension for RDMA, and moving on to more opportunities available on other platforms which can be introduced to FreeBSD.
