Storage Requirements
Implementation of Virtual Volumes replication depends on your array and might be different for storage
vendors. Generally, the following requirements apply to all vendors.
n
The storage arrays that you use to implement replication must be compatible with Virtual Volumes.
n
The arrays must integrate with the version of the storage (VASA) provider compatible with Virtual
Volumes replication.
n
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.
n
When applicable, replication groups and fault domains for Virtual Volumes must be preconfigured on
the storage side.
For more information, contact your vendor and see VMware Compatibility Guide.
vSphere Requirements
n
Use the vCenter Server and ESXi versions that support Virtual Volumes storage replication.
vCenter Server and ESXi hosts that are older than 6.5 release do not support replicated Virtual
Volumes storage. Any attempts to create a replicated VM on an incompatible host fail with an error.
For information, see VMware Compatibility Guide.
n
If you plan to migrate a virtual machine, make sure that target resources, such as the ESXi hosts and
Virtual Volumes datastores, support storage replication.
Virtual Volumes and Replication Groups
When your storage offers replication services, in addition to storage containers and protocol endpoints,
your storage administrator can configure replication groups on the storage side.
vCenter Server and ESXi can discover replication groups, but do not manage their life cycle. Replication
groups, also called consistency groups, indicate which VMs and virtual disks must be replicated together
to a target site. You can assign components of the same virtual machine, such as the VM configuration
file and virtual disks, to different preconfigured replication groups. Or exclude certain VM components
from replication.
