VAAI -- VMware vSphere vStorage APIs

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
