Procedure
1 Navigate to the host.
2 Click the Configure tab.
3 Under Virtual Flash, select Virtual Flash Resource Management and click Add Capacity.
4 From the list of available flash drives, select one or more drives to use for the virtual flash resource
and click OK.
The virtual flash resource is created. The Device Backing area lists all the drives that you use for the
virtual flash resource.
Enable I/O Filter Data Services on Virtual Disks
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.
Prerequisites
For the caching I/O filters, configure the virtual flash resource on your ESXi host.
Procedure
1 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.
See Create a VM Storage Policy for Host-Based Data Services.
2 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.
Assign the I/O Filter Policy to Virtual Machines
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.
You can assign the I/O filter policy during an initial deployment of a virtual machine. This topic describes
how to assign the policy when you create a new virtual machine. For information about other deployment
methods, see the vSphere Virtual Machine Administration documentation.
Note You cannot change or assign the I/O filter policy when migrating or cloning a virtual machine.
