WebMediated Devices. The Mellanox mediated devices deliver flexibility in allowing to create accelerated devices without SR-IOV on the Bluefield® system. These mediated devices support NIC and RDMA, and offer the same level of ASAP 2 offloads as SR-IOV VFs. Mediates devices are supported using mlx5 sub-function acceleration technology. WebTherefore, RDMA provides ultra-low latency (∼1μs) and high throughput (40/100Gbps) with little CPU over-head. Nowadays, RDMA has been deployed in data-centers at scale with RDMA over Converged Ethernet (RoCE) v2 [26, 49]. Existing RDMA is a single path transport, i.e., an RDMA connection only flows along one network path.
