The following figure shows the required cabling for the Ready Stack workload domain components. The management domain servers use vSAN storage so do not require connectivity to the Connectrix switches.

Figure 2.         Dell EMC Ready Stack cabling

Networking technology of 100 GbE requires QSFP28 cables, and 25 GbE requires SFP28 cables. We recommend using Dell EMC Networking passive copper direct attach cables, which are available in various lengths to meet your rack layout requirements. Dell EMC Networking active optical cables are also available for longer distances and dense rack configurations.

Connectrix DS-6620B switches are prepopulated with the required FC optics. Unity XT x80 storage and PowerEdge servers require additional 16 GB small form-factor pluggable (SFP) FC adapters. Dell EMC Multimode LC/LC fiber optic cables are required between the PowerEdge server and Unity XT x80 storage array and the Connectrix FC switches. Cat 5e or Cat 6 Ethernet cabling is required for Dell EMC iDRAC, Connectrix, and Unity XT x80 management connectivity. For small configurations, you can connect 1 GbE devices to ToR switches by using a 1000Base-T SFP transceiver, which eliminates the need for the Dell EMC S4148T-ON switch in some cases.
