VxRail is configured with a base set of virtual networks that require connectivity for the cluster to be properly built and to operate. VxRail depends on these connections to the physical network to enable cluster operations.
Every VxRail cluster requires two separate virtual networks for management purposes. The external management network enables connectivity to the VxRail cluster for IT administration purposes, while the internal management network supports node discovery for VxRail build and expansion purposes.
For clusters leveraging VMware vSAN for primary storage, connectivity for the VMware vSAN network between the nodes is required. Connectivity between nodes for the VMware vSphere vMotion network is also required.
