UEK 8 includes Remote Direct Memory Access (RDMA) features that are provided in the upstream kernel, with the addition of Ksplice and DTrace functionality. RDMA enables direct memory access between two systems that are connected by an InfiniBand or RoCE network. RDMA facilitates high-throughput and low-latency networking in clusters.
