What to do next
If storage placement requirements for the configuration file or the virtual disks change, you can later
modify the virtual policy assignment. See Change Storage Policy Assignment for Virtual Machine Files
and Disks.
Change Default Storage Policy for a Virtual Volumes Datastore
For virtual machines provisioned on Virtual Volumes datastores, VMware provides a default No
Requirements policy. You cannot edit this policy, but you can designate a newly created policy as default.
Prerequisites
Create a storage policy compatible with Virtual Volumes.
Procedure
1 Browse to the Virtual Volumes datastore whose default storage policy you want to change.
2 Click the Configure tab.
3 Under Settings, click General.
4 Click Edit in the Default Storage Policy pane.
5 From the list of available storage policies, select a policy to designate as the default and click OK.
The selected storage policy becomes the default policy for the Virtual Volumes datastore. vSphere
assigns this policy to any virtual machine objects that you provision on the Virtual Volumes datastore
when no other policy is explicitly selected.
Virtual Volumes and Replication
Virtual Volumes supports replication and disaster recovery. With the array-based replication, you can off-
load replication of virtual machines to your storage array and use full replication capabilities of the array.
You can replicate a single VM object, such as a virtual disk. You can also group several VM objects or
virtual machines to replicate them as a single unit.
Array-based replication is policy driven. After you configure your Virtual Volumes storage for replication,
information about replication capabilities and replication groups is delivered from the array by the storage
provider. This information shows in the VM Storage Policy interface of vCenter Server.
You use the VM storage policy to describe replication requirements for your virtual machines. The
parameters that you specify in the storage policy depend on how your array implements replication. For
example, your VM storage policy might include such parameters as the replication schedule, replication
frequency, or recovery point objective (RPO). The policy might also indicate the replication target, a
secondary site where your virtual machines are replicated, or specify whether replicas must be deleted.
