6.5.1

The I/O filter capabilities are displayed on the Common rules page of the VM Storage Policies wizard.
The policy that enables I/O filters must include common rules. However, adding placement rules is
optional.
Depending on the I/O filters installed in your environment, the data services can belong to various
categories, including caching, replication, and so on. By referencing the specific category in the storage
policy, you request the service for your virtual machine.
If your I/O filters and storage offer the same service category, for example, encryption, your policy can
request this service from both providers. As a result, the virtual machine data is encrypted twice, by the
I/O filter and your storage. However, replication provided by Virtual Volumes and replication provided by
the I/O filter cannot coexist in the same storage policy.
