How can you verify vStorage APIs for Array Integration (VAAI) is enabled?

A.
“VAAI” listed on the Hard Disk properties page for any VMDK stored on a compliant array

B.
“Hardware Acceleration” listed on the Hard Disk properties page for any VMDK stored on a
compliant array

C.
“VAAI” column for any datastore created on a compliant array

D.
“Hardware Acceleration” column for any datastore created on a compliant array

Explanation:
If you go to Host > Configuration > Storage, you can see the Hardware Acceleration
Status in the panel on the right side.
For each storage device and datastore, the vSphere Client displays the hardware acceleration
support status in the Hardware Acceleration column of the Devices view and the Datastores view.
