WebNov 4, 2024 · DCB flow control status Priority-based flow control is essential if the upper layer protocol, such as Fiber Channel, assumes a lossless underlying transport. DCB flow control can be enabled or disabled either globally or for individual network adapters. 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.
