WebRDMA transmission works in NICs with three queues: Send Queue (SQ), Receive Queue (RQ), and Completion Queue (CQ). When an RDMA application starts to work, it must create its SQ, RQ, and CQ in the RDMA NIC, and registers regions in memory for its processing. The work scheduling unit of RDMA is a Queue Pair (QP), which consists of one SQ and one RQ. 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.
