Second, companies using critical applications and serious about their
users and environments don't care about the cost of a few more servers
if ever it was required.
Unfortunately, when you're trying to scale, sometimes you hit a brick wall
(literally - part of my machine room is curtained off with dust-suppression
plastic sheeting because they're cutting through the wall). Having to bring in
another 1.5 megawatt power feed because your first two are at capacity makes
you suddenly care a lot about the total cost. :)
Oh, and of course that means the cooling system needs to be checked and
possibly ugraded, and 1.5 megawatt backup diesels cost a fair chunk of change,
and, and,. and... ;)
(And yes, we already did the whole virtualization thing - otherwise we'd have been
up against the power wall several years ago).
