Enabling data services that I/O filters provide is a two-step process. You create a virtual machine policy based on data service capabilities that I/O filters provide, and then attach this policy to a virtual machine.

For caching I/O filters, configure the virtual flash resource on your ESXi host.

To enable I/O filters for virtual machines, you must first create a virtual machine policy that lists data service capabilities provided by the I/O filters.

To activate data services that I/O filters provide, associate the I/O filter policy with virtual disks. You can assign the policy when you create or edit a virtual machine.
