Logical Design for vSAN for the Management Domain

Because vSAN is a cost-efficient storage technology that provides simple storage management user experience, the default management cluster uses vSAN for principal storage. By using vSAN, you can also configure a vSAN stretched cluster in the domain.
vSAN Logical Design
Management VMs on management ESXi hosts are connected to a principal datastore over vSAN. The management ESXi hosts are also connected to an optional supplemental datastore.
vSAN Logical Design
Single VMware Cloud Foundation Instance with a Single Availability Zone
Single VMware Cloud Foundation Instance with Multiple Availability Zones
Multiple VMware Cloud Foundation Instances
  • vSAN clusters in the management domain
  • Four ESXi hosts per vSAN cluster
  • All-flash vSAN configuration
  • The default management cluster is a vSAN stretched cluster
  • Eight ESXi hosts in the vSAN stretched cluster
    Four ESXi hosts in each availability zone
  • vSAN witness appliance in a third location to the SDDC
  • All-flash configuration
In each instance:
  • vSAN clusters in the management domain
  • Four ESXi hosts per vSAN cluster
  • All-flash vSAN configuration
  • vSAN witness appliance in a third location, for example, another instance of VMware Cloud Foundation
In each instance with multiple availability zones:
  • The management domain default cluster is a vSAN stretched cluster.
  • Eight ESXi hosts in the stretched cluster with four ESXi hosts in each availability zone.
  • vSAN witness appliance in a third location, for example, another instance of VMware Cloud Foundation.
