The VCF on VxRail solution natively supports two different multisite options depending on the distance and latency between the sites and the type of protection needed for the workloads. Multi availability zones are offered by VxRail vSAN stretched clusters for the Mgmt WLD and VI WLDs between the two availability zones. This is typically only for sites within the same Metro area due to the latency requirements for stretched vSAN. New to VCF 4.2 NSX-T federation is now supported which enables support for dual-region VCF instances which can be located at much greater distances as there is no stretched cluster requirement.
