Getting back to the comment about the proliferation of ( usually wintel)
single application servers. In my experience, this occurred because
different business units liked having and controlling their own
server(s), and individually each little server was not very power hungry
anyway. Not like that great big 9672 (!!!).
All of a sudden we have no mainframe and 250+ wintel servers... (
and,indeed! no business unit beholding to any other).
Sounds a bit like all of the other centralised vs de-centralised
support/cost issues.
I remember when we went CMOS, then RAMAC and Magstar, our power
consumption went through the floor. But now look at us !!! Our data
centre is hotter and greedier than it has ever been. (by far!) (and our
cpu utilisation is about 5% if it's lucky.).
VMWARE , I suspect, *might* reduce things to being only 10 times worse,
as distinct from the 20 times as bad we are now.

Back when I did Capacity Analysis & Planning, I was required to cost out
the complete costs of ANY upgrade. This meant I had to compute air and
water cooling costs, equipment power consumption and costs of any wiring
changes in the computer room; not to mention the actual upgrade costs.
Imagine, if you can, the hair-pulling and teeth gnashing if the
little-server boys had to jump through the same hoops!
Dell and Sun stocks would be in the bargain basement! :-)
