Enabling data services that I/O filters provide is a two-step process. You create a virtual machine policy based on data services that the I/O filters provide, and then attach this policy to a virtual machine.
For the caching I/O filters, configure the virtual flash resource on your ESXi host.
- Define a VM policy based on I/O filter services.
You must first create a virtual machine policy that lists data services provided by the I/O filters.
- Assign the I/O filter policy to a virtual machine.
To activate data services that the I/O filter provides, associate the I/O filter policy with virtual disks. You can assign the policy when you provision the virtual machine.
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.
