We very recently went through adding Grid cards to our VMware View infrastructure. The Grid K1 & K2 cards are a tradeoff on either more kepler processors or more cuda cores in addition to the quantity of RAM. VMware View can utilize a Grid card in either vSGA or vDGA modes (shared or direct passthrough of a kepler processor). From what I can discern, Dell only officially supports the Grid cards in their R720 server. That particular chassis can only accept 2 Grid cards max. So you can get your choice of 2, 4, 6, or 8 kepler processors. If you're using vDGA mode, you're creating a direct VDI desktop allocation of that core with DirectPath I/O. While this means that one desktop is going to have great performance, it means it isn't available for anyone else and you lose vMotion capability. If you run in vSGA mode, the performance per machine isn't as good as vDGA but more desktops can utilize the hardware. There arn't any good whitepapers I've found yet describing how far you can stretch a Grid K1, but the rule of thumb I got from another company who has ran them through their benchmark lab got around 25 desktops per K1 max. Therefore, assuming you've got a pair of them that means you can run ~50 desktops with a reduced performance when compared to vDGA. The technology still appears to be young to me, but we decided to take a chance and see how far we could take it.
