Eric, I think the point here is that for years data centers have proliferated servers that are single application and low utilization. This has driven their power usage sky high. I don't know if power companies in other states have started to put caps on power usage like PG&E has, but I have heard that it is happening in Europe where the power companies are basically government owned. I've been in the capacity planning profession for about 20 years. Traditionally that involves planning for CPU consumption, memory, and storage. Now, in many shops that traditional capacity planner is adding power consumption to his/her list of items to trend and control in some way. This is another perfect reason to virtualize. Of course we all know that the mainframe is the best, most mature virtual machine available. Now, if we can just get management to realize that.
