When you define storage policies for virtual machines, you specify storage requirements for applications that will run on the virtual machines.
A storage policy can be based on data services that are advertised by a storage entity or on datastore tags. The policy can also reference common data services that the I/O filters framework provides.
What to do next
You can apply this storage policy to virtual machines. If you use object-based storage, such as Virtual SAN and Virtual Volumes, you can designate this storage policy as the default.
