Enable I/O Filter Data Services on Virtual Disks
Enabling data services that I/O lters provide is a two-step process. You create a virtual machine policy
based on data service capabilities that I/O lters provide, and then aach this policy to a virtual machine.
Prerequisites
For caching I/O lters, congure the virtual ash resource on your ESXi host.
Procedure
1 Dene a VM Policy Based on I/O Filter Capabilities on page 249
To enable I/O lters for virtual machines, you must rst create a virtual machine policy that lists data
service capabilities provided by the I/O lters.
2 Assign the I/O Filter Policy to Virtual Machines on page 251
To activate data services that I/O lters provide, associate the I/O lter policy with virtual disks. You
can assign the policy when you create or edit a virtual machine.
Define a VM Policy Based on I/O Filter Capabilities
To enable I/O lters for virtual machines, you must rst create a virtual machine policy that lists data service
capabilities provided by the I/O lters.
The I/O lter capabilities are displayed on the Common Rules page of the VM Storage Policies wizard.
Prerequisites
