RE: Optimizing network power usage

I'm a big fan of the Intel NUC's. They are a little pricey, but they are perfect for a lot of specialized uses. I was going to try to cluster a handful of them together at one point to see how that worked but I got busy doing other things and never followed through with it. What software are you looking at for the clustering? I was looking at Nutanix or whatever it is called.
