WebRDMA over Converged Ethernet (RoCE) is supported with PVRDMA. The beauty of RoCE is that a ethernet fabric can be used. There's not explicit requirement for a seperate fabric like with Infiniband. The ethernet fabric needs to support RDMA, primarily by supporting Priority Flow Control (PFC). PVRDMA supports both RoCE v1 and v2. WebAug 15, 2024 · RDMA can be enabled in storage networking with protocols like RoCE (RDMA over Converged Ethernet), iWARP (internet wide area RDMA protocol), and Infiniband. iWARP is roughly an RDMA over TCP/IP. It uses TCP and Stream Control Transmission Protocol (SCTP) for data transmission. RoCE enables RDMA over Ethernet.
