WebRemote Direct Memory Access (RDMA) is a technology that allows computers in a network to exchange data in main memory without involving the processor, cache or operating system of either computer. Like locally based Direct Memory Access ( DMA ), RDMA improves throughput and performance because it frees up resources. RDMA also … WebIn computing, remote direct memory access ( RDMA) is a direct memory access from the memory of one computer into that of another without involving either one's operating system. This permits high-throughput, low- latency networking, which is especially useful in massively parallel computer clusters . Overview [ edit]
