Network layout

  • The following chart illustrates the network layout that is used by VxRail in the configuration of a vSAN 2-node cluster. Although VMware supports using an alternative vLAN other than vSAN vLAN for WTS, VxRail requires the WTS to have its own vLAN. This layout is specific to the VxRail vSAN 2-node cluster. The configuration of the management cluster is slightly different as described in the VxRail Network Planning Guide.
