Common rules are based on data services that are generic for all types of storage and do not depend on a datastore. These data services become available in the VM Storage Policies interface when you install third-party I/O filters developed through vSphere APIs for I/O Filtering. You can reference these data services in a storage policy.


  1. On the Common Rules page, enable common rules by selecting Use common rules in the storage policy.
  2. From the Add rule drop-down menu, select a data service to include in the rule.
  3. Select a provider of the data service.
    If the same data service, for example Replication, is offered by different providers, you cannot add more than one rule referencing this data service.
  4. Specify values for the rule and click Next.
