You can skip this section if your plans do not include deploying a VxRail stretched cluster or a VxRail 2-node cluster.
VxRail supports two types of vSAN clusters that require a witness to serve as a quorum if there is a failure. They are the VxRail stretched cluster and the VxRail 2-node cluster. If your plans include deploying one of these VxRail cluster types, planning for a vSAN witness must be considered first before building the VxRail cluster. Full details on the preparation and planning steps for these two VxRail cluster types can be found in the Dell VxRail vSAN Stretched Cluster Planning Guide or the Dell vSAN 2- Node Cluster Planning and Preparation Guide. This chapter provides an overview of the networking planning steps for the required vSAN witness.
