VAAI

The following outputs shows that Hardware Acceleration is enabled on ESX to take advantage of the storage primitives on ESX 4.1 and ESXi 5.x. Use the esxcfg-advcfg command to check that the options are set to 1 (enabled):

# esxcfg-advcfg -g /DataMover/HardwareAcceleratedMove
# esxcfg-advcfg -g /DataMover/HardwareAcceleratedInit
# esxcfg-advcfg -g /VMFS3/HardwareAcceleratedLocking

To check if the storage array supports VAAI primitives, you can use the following command:

esxcli storage core device vaai status get -d naa.60a98000572d54724a346a6170627a52
