Enabling VAAI Block Zeroing For Compellent Arrays

Recently, Compellent released VAAI (Block Zeroing) support for their arrays. Although we are still waiting on full VAAI support, block zeroing support is a great addition.

To enable this feature, you must install the .vib file from Compellent and the following changes need to be made on your hosts:

esxcli corestorage claimrule add --claimrule-class=Filter --plugin=VAAI_FILTER --type=vendor --vendor=COMPELNT --autoassign

esxcli corestorage claimrule add --claimrule-class=VAAI --plugin=VMW_VAAIP_T10 --type=vendor --vendor=COMPELNT --autoassign

esxcli corestorage claimrule load --claimrule-class=Filter

esxcli corestorage claimrule load --claimrule-class=VAAI

esxcli corestorage claimrule run --claimrule-class=Filter
