Remote Direct Memory Access (RDMA) Over Converged Ethernet (RoCE) adapters support RDMA connectivity over converged networks. RDMA enables sending data over a network without involving the CPU in the transfer. It provides appreciable IOPS performance in comparison to other network-based storage connectivity options. Enabling RDMA over a Converged Ethernet network infrastructure provides faster data transfer for network-intensive applications through lower I/O latencies on this network.
Understand the following guidelines for RoCE-supported adapters:
