Manipulating the Hardware Acceleration VAAI primitives
There are two new vaai primitives available in vsphere 5.0. These provide hardware
acceleration for NAS and Thin Provisioning. Using these primitives offload certain
operations to the array, hence reducing cpu overhead on the host and improving cold
migrations and cloning duration.
From the VMA:
List all plugins installed:
# esxcli --server 10.1.1.1 software vib list
Install a vaai vib:
# esxcli --server 10.1.1.1 software vib install -v | --viburl=url_here
Uninstall a vaai vib:
# esxcli --server =10.1.1.1 software vib remove -v| --vibname=name
Additional local commands:
# esxcfg-scsidevs -l | egrep "Display Name:VAAI Status"
# esxcli storage core dvice vaai status get
