The VCF on VxRail solution natively supports a stretched-cluster configuration for the Mgmt WLD and VI WLDs between two availability zones. The stretched-cluster configuration combines both standard VxRail procedures and automated steps that are performed by using SOS commands from the SDDC Manager. The Witness deployment is manually deployed and configured, and the SDDC Manager automates the configuration of the vSAN stretched cluster.
Note: Dual Region disaster recovery is not yet supported in VCF on VxRail version 3.10.01.
