A virtual machine that runs on a Virtual Volumes datastore requires a VM storage policy.
A VM storage policy is a set of rules that contains placement and quality-of-service requirements for a virtual machine. The policy enforces appropriate placement of the virtual machine within Virtual Volumes storage and guarantees that storage can satisfy virtual machine requirements.
You use the VM Storage Policies interface to create a Virtual Volumes storage policy. When you assign the new policy to the virtual machine, the policy enforces that the Virtual Volumes storage meets the requirements.
Virtual Volumes Default Storage Policy
For Virtual Volumes, VMware provides a default storage policy that contains no rules or storage requirements, called Virtual Volumes No Requirements Policy. 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.
