A new white paper entitled VMware vSphere Storage APIs – Array Integration (VAAI) is now available. You can download the paper from the VMware Technical Resources web site here. This paper includes a description of all of the VAAI block, NAS & Thin Provisioning primitives. It also looks at how VAAI in implemented in our Pluggable Storage Architecture (PSA) model, as well as some tools available to you to troubleshoot and monitor VAAI primitive usage.
Hope you find it useful.
