In VMware Cloud Foundation, you deploy the management domain and NSX-T workload domain of the SDDC with a configuration for supporting multiple availability zones. The use of vSAN stretched cluster also requires that you allocate a third location for deploying the vSAN witness appliance that is not local to the ESXi hosts on either side of the stretched cluster.
