Customers who don't run datacenters general don't understand the issues around high density computing, and most enterprises I deal with don't care about the cost. More and Faster is their vocabulary. > If you move all the entreprise services onto virtual servers > then you can free up space for colo/hosting services. We do quite a bit of VMWare and Xen, both our own and our customers. We have found power consumption still goes up, simply because there is always a backlog of the need of resources. In other words, it's almost "if you build it they will come" relates to CPU cycles as well. I have never seen a decrease in customer power consumption when they have virtualized. They still have more iron, with a lot more VM's. > You can even still sell to bulk customers because few will > complain that they have to deliver equipment to three > dara centers, one two blocks west, and another three blocks > north.

Especially the ones with lots of fiber channel and InfiniBand.
