RDMA Network Fabric Switch-to-Server Cabling Connections X8M
Table 20-8 lists the location, ports, and cables for the InfiniBand connections from the gateway leaf switches to the servers in a Recovery Appliance X8M full rack. The port numbers and cable lengths are the same in racks with fewer storage servers. The switches are located in rack units 20 and 22.
All cables are black quad data rate (QDR) cables.
