-Disclosure NetApp Employee-
I'm a little disappointed that NetApp didn't get a mention in the article, given that based on the information I have available to me, our customers are arguably better prepared for vVols than any of the vendors listed above. (it's a little hard to be specific without breaking NDA). As an indication of this, it's worth noting that unless something has changed recently, we're the only vendor offering an open beta for vVol functionality with the latest version of ONTAP.
We posted a 3 part intro to Virtual Volumes on youtube for VMworld last year. We are planning to created updated videos based on the latest builds.
