WebJun 19, 2024 · In RDMA, almost everything is off-loaded from the CPU and pushed to the “rNIC” (RDMA NIC). The goals of RDMA are to reduce the context switches between user and kernel space, allow direct memory copies to and from the host CPU, and offload protocol processing to the NIC from the CPU. WebRoCE enables you to write to compute or storage elements using RDMA over an Ethernet network instead of using host CPUs. RoCE relies on ECN and PFC to operate. Cumulus Linux supports features that can enable lossless Ethernet for RoCE environments. While Cumulus Linux can support RoCE environments, the end hosts must support the RoCE protocol.
