Cloud Foundation for VxRail will support two or four Ethernet connections per node into your supporting physical network. For the two-port node option, all Cloud Foundation and NSX-T traffic is consolidated onto the two ports. With the four-port node option, the vMotion and vSAN network traffic are moved to the second pair of ports. For fault protection, each node port connects to a separate physical switch.

Once Cloud Foundation on VxRail is deployed, the network traffic cannot be migrated onto other node ports if the two-port deployment option is selected. Ensure there is sufficient networking capacity for the planned workload before Cloud Foundation on VxRail deployment if the two-port option is selected.
