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.
- On the Common Rules page, enable common rules by selecting Use common rules in the storage policy.
- From the Add rule drop-down menu, select a data service to include in the rule.
- 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.
- Specify values for the rule and click Next.
