WebRemote Direct Memory Access is a technology that enables two networked computers to exchange data in main memory without relying on the processor, cache or operating system of either computer. Web30 jul. 2024 · Remote Direct Memory Access (RDMA) plays a key role in supporting performance-hungry datacenter applications. However, existing RDMA technologies are ill-suited to multi-tenant datacenters, where applications run at massive scales, tenants require isolation and security, and the workload mix changes over time.
WebRemote direct memory access. 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 .
