VMware provides default storage policies for Virtual SAN and Virtual Volumes datastores.

Virtual SAN Default Storage Policy

When you do not select any Virtual SAN policy, the system applies the default storage policy to all virtual machine objects that are provisioned on a Virtual SAN datastore.

The default Virtual SAN policy that VMware provides has the following characteristics:

  • You cannot delete the policy.

  • The policy is editable. To edit the policy, you must have the storage policy privileges that include the view and update privileges.

  • When editing the policy, you cannot change the name of the policy or the Virtual SAN storage provider specification. All other parameters including rules are editable.

  • You can clone the default policy and use the copy as a template to create another storage policy.

  • The Virtual SAN default policy is compatible only with Virtual SAN datastores.

  • You can create a VM storage policy for Virtual SAN and designate it as the default.

Virtual Volumes Default Storage Policy

For Virtual Volumes, VMware provides a default storage policy that contains no rules or storage requirements, called VVol No Requirements Policy. As with Virtual SAN, this policy is applied to the VM objects when you do not specify another policy for the virtual machine on the Virtual Volumes datastore. With the No Requirements policy, storage arrays can determine the optimum placement for the VM objects.

The default No Requirements policy that VMware provides has the following characteristics:

  • You cannot delete, edit, or clone this policy.

  • The policy is compatible only with the Virtual Volumes datastores.

  • You can create a VM storage policy for Virtual Volumes and designate it as the default.
