You can get the drivers right off Sandisk's site. I just made a new account and grabbed the vSphere drivers. I think FusionIO used to lock them down but Sandisk doesn't.
I'd have to install it to check fio-status. If someone really wants me to I can..if it runs under vSphere. I don't have any other non-Apple systems in my house outside of my 3 vSphere hosts. I had two of these that I was using for vSphere and Pernix FVP testing. I already sold one of the two.
