WebConventional RDMA •RDMA traditionally used in Infinibandclusters. –A different network protocol supporting high bandwidth. •Infinibandlinks use credit-based flow control. –Losses are rare. •Transport layer in RDMA NICs not designed to deal with losses efficiently. –Receiver discards out-of-order packets. Web4.Configuring Guest RDMA 1. Install Windows Server 2024 2. Install the Hyper-V Role and the Data Center Bridging (DCB) feature. 3. Configure QoS (Quality-of-Service), DCB, PFC, ETS. Make sure that the server NIC and QoS configuration matches the switch configuration. 4. Configure Hyper-V SET (Switch Embedded Team). Figure 9 - vSwitch Configuration
