c Define rules for the data service category by specifying an appropriate provider and values for the
rules. Or select the data service from the list of predefined components.
Option Description
Component Name
This option is available if you have predefined storage policy components in
your database. If you know which component to use, select it from the list to
add to the VM storage policy.
See all Review all component available for the category. To include a specific
component, select it from the list and click OK.
Custom Define custom rules for the data service category by specifying an appropriate
provider and values for the rules.
Note If you use encryption with other I/O filters, set the Allow I/O filters before encryption
parameter to True, so that other filters, such as replication, can analyze clear text data before it is
encrypted.
d Add more components to request other data services.
You can use only one component from the same category, for example caching, per a set of
common or regular rules.
e Click Next.
7 If your policy includes placement rules, on the Rule Set page, specify storage placement
requirements and click Next.
Note If you plan to migrate the virtual machine with the I/O filters across different types of
datastores, make sure that the policy includes placement rules for every target datastore. For
example, if you migrate your virtual machine between the VMFS and Virtual Volumes datastores,
create a mixed VM storage policy. The policy must include tag-based rule for the VMFS datastore and
rules for the Virtual Volumes datastore.
8 On the Storage Compatibility page, review the list of available datastores and click Next.
To be compatible with the I/O filter policy, datastores must be connected to host with I/O filters and
satisfy storage requirements of the policy.
9 Complete the creation of the storage policy and click Finish.
The new policy is added to the list.
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.
