When you enable vVols with replication, in addition to general vVols requirements, your environment must satisfy several specific prerequisites.
For general vVols requirements, see Before You Enable vVols.
Implementation of vVols replication depends on your array and might be different for storage vendors. Generally, the following requirements apply to all vendors.
- The storage arrays that you use to implement replication must be compatible with vVols.
- The arrays must integrate with the version of the storage (VASA) provider compatible with vVols replication.
- The storage arrays must be replication capable and configured to use vendor-provided replication mechanisms. Typical configurations usually involve one or two replication targets. Any required configurations, such as pairing of the replicated site and the target site, must be also performed on the storage side.
- When applicable, replication groups and fault domains for vVols must be preconfigured on the storage side.
For more information, contact your vendor and see VMware Compatibility Guide.
- Use the vCenter Server and ESXi versions that support vVols storage replication. vCenter Server and ESXi hosts that are older than 6.5 release do not support replicated vVols storage. Any attempts to create a replicated VM on an incompatible host fail with an error. For information, see VMware Compatibility Guide.
- If you plan to migrate a virtual machine, make sure that target resources, such as the ESXi hosts and vVols datastores, support storage replication.
