Overview of VxRail Stretched Cluster
VxRail Stretched Cluster is designed for an active-active data center solution, and it can provide redundancy and failure protection across two separate physical sites. In Figure 7.1, VxRail Stretched Cluster is built between two individual sites, including two data sites (Preferred Site and Secondary Site) and one witness site. The witness host deploys a third site that contains the witness components of the VM objects. The VMs can continue to provide the services when one of the data sites fails. This is the main feature of VxRail Stretched Cluster:

If you choose the deployment of VxRail Stretched Cluster, you need to consider the following:
- The minimum supported configuration for VxRail Stretched Cluster is 1+1+1 (two VxRail nodes plus one witness). The maximum supported configuration is 15+15+1 (30 VxRail nodes plus 1 witness).
