After you create  VM storage policy, you may apply it to a virtual machine. You apply the storage policy in two ways  first when you provisioning the virtual machine else configuring its virtual disks. Depending on its type and configuration, the policy might serve different purposes. The policy can select the most appropriate datastore for the virtual machine and enforce the required level of service Or it can enable specific data services for the virtual machine and its disks.
