Web1.Introduction of Remote Direct Memory Access (RDMA) Remote Direct Memory Access (RDMA) is a great technology that enables computers to transfer data across the network without involving CPU or OS resources of the hosts involved (Compute/Storage), improving throughput and performance, reducing latency and CPU overhead. In 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.

WebAug 3, 2011 · RDMA enables accessing memory data on a remote machine without passing the data through the CPUs on the system. RDMA therefore enables data to be transferred between storage and clients with higher throughput and lower CPU usage. NFS over RDMA, as defined in RFC8267, uses the advantages of RDMA. WebAug 2, 2004 · RDMA optimizes the process at the bottom of the stack. It is more efficient, reduces latency and offloads the server CPU. But will the presence of massive …
