DMA (in networking) is an operation which access the memory directly from the NIC (Network Interface Controller), without involving the CPU. RDMA is the same idea, but the direct memory access is done by a remote machine. greenfield nh weather forecastRoCE defines how to perform RDMA over Ethernet while the InfiniBand architecture specification defines how to perform RDMA over an InfiniBand network. RoCE was expected to bring InfiniBand applications, which are predominantly based on clusters, onto a common Ethernet converged fabric. Others expected that InfiniBand will keep offering a higher bandwidth and lower latency than what is possible over Ethernet. greenfield northampton cooperative
