Disagreed. 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.

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.

Send me those customers, because I haven't seen them. Especially the
ones with lots of fiber channel and InfiniBand.
