The VxRail product does not have a backplane, so the adjacent ‘top-of-rack’ 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 ‘top-of-rack’ 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 architected to enable efficiency with the physical ‘top-of-rack’ 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.
