On top of that is back up power supply. We are increasing our UPS
and other back up power supplies over the next several years. They
wont look at what increasing the servers are doing to other requirements.
They simply see the cost of the mainframe is x. They never see
the cost of servers. As Steve pointed out, they likely dont even know
the tco of servers. But that is not important. The mainframe is too
expensive in their mind. The mainframe is too passe.

Keep an eye on the horizon for the great equalizer: Power. When the
electric company says "No more power is available to this building" and
you have to build/buy a new building to house the ever-growing server
farm, the price tag may generate some second thoughts. It might be
educational to discover how close you are to the limits of your data
centers. Some folks don't pay attention to electricity until too late.
Not only does a discrete server consume power, it also gives off heat.
The more racks you put in, the more cooling you need. And let's not
forget the bigger UPS and generators, too.
Of course, this is no way reduces the *desire* of some people to get off
the mainframe. Just their ability.
