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 the I/O filters provide, and then attach this policy to a virtual machine.

Before you begin

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

What to do next

If you later want to disable the I/O filter for a virtual machine, you can remove the filter rules from the VM storage policy and re‐apply the policy. See Edit or Clone a VM Storage Policy. Or you can edit the settings of the virtual machine and select a different storage policy that does not include the filter.
