When your datastore is not represented by a storage provider and does not display its capabilities in the Storage Profile-Based Management system, use tags to encode information about the datastore. You can then reference these tags when defining a storage policy for a virtual machine.

You can apply a new tag that contains storage information to a datastore. For information about tags, their categories, and how to manage tags, see the vCenter Server and Host Management documentation.


  1. Browse to a datastore in the vSphere Web Client inventory.
  2. Click the Manage tab and click Tags.
  3. Click the New Tag icon.
  4. In the vCenter Server drop-down menu, select the vCenter Server instance on which to create the tag.
  5. Type a name and a description for the tag.

    For example, you can specify a broad storage level definition, such as Gold Storage, or indicate a property that is not communicated through a storage provider, such as geographical location or administrative group.

    Tag Property



    Fault Tolerance


    Storage that has a capacity over 2TB and is fault-tolerant

  6. In the Category drop-down menu, select an existing category or create a new category.
  7. (Optional) To create a new category, follow these steps:
    1. Select New Category to expand the dialog box.
    2. Specify the category options.

      Category Property


      Category Name

      Storage Category


      Category for tags related to storage


      Many tags per object

      Associable Object Types

      Datastore and Datastore Cluster

  8. Click OK.


The new tag is assigned to the datastore.

What to do next

You can reference the tag when adding tag-based rules to the storage policy. See Add or Edit Tag-Based Rules.

The datastore appears on a list of compatible storage resources for virtual machines that use the policy.
