You can stretch a vSAN cluster in a workload domain across two availability zones within a region. Both availability zones must contain an equal number of hosts to ensure failover in case any of the availability zones goes down.
- The cluster uses static IP addresses for the NSX Host Overlay Network TEPs.
- The cluster has a vSAN remote datastore mounted on it.
- The cluster shares a vSAN Storage Policy with any other clusters.
- The cluster is enabled for Workload Management (vSphere with Tanzu).
- Planned maintenance
You can perform a planned maintenance on an availability zone without any downtime and then migrate the applications after the maintenance is completed.
- Automated recovery
Stretching a cluster automatically initiates VM restart and recovery, and has a low recovery time for the majority of unplanned failures.
- Disaster avoidance
With a stretched cluster, you can prevent service outages before an impending disaster.
This release of VMware Cloud Foundation does not support deleting or unstretching a cluster.
