The VxRail product does not have a backplane, so the adjacent ToR switch enables all connectivity between the nodes that comprise a VxRail cluster. All the networks (management, storage, virtual machine movement, guest networks) configured within the VxRail cluster depend on the ToR switches for physical network transport between the nodes, and connectivity upstream to data center services and end users.
The network traffic configured in a VxRail cluster is Layer 2. VxRail is developed to enable efficiency with the physical ToR switches through the assignment of virtual LANs (VLANs) to individual VxRail Layer 2 networks in the cluster. This functionality eases network administration and integration with the upstream network.
