How can you tell if VAAI is enabled?

To determine if VAAI is enabled using the vSphere Client:

1. In the vSphere Client inventory panel, click the host.
2. Click the Configuration tab, then click Advanced Settings under Software.
3. Check that these options are set to 1 (enabled):
   
   DataMover.HardwareAcceleratedMove
DataMover.HardwareAcceleratedInit
VMFS3.HardwareAcceleratedLocking

What do I need to know about the Hardware Acceleration Support Status?
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.

The status values are Unknown, Supported, and Not Supported. The initial value is Unknown. The status changes to Supported after the host successfully performs the offload basic operations. If the offload operation fails, the status changes to Not Supported.
