Sean, I could not be in more agreement with you. I have written a white paper that discusses this issue. It covers some of the basics of cooling and power but it also takes it down to Ohms Law and shows a few excel worksheets for calculations of single systems as well as roll-up's for racks of equipment. Here is a link to the white-paper: http://www.colosource.com/whitepaper/Coolingandpowerpaper.pdf Please let me know what you think if you have a chance to give it a read. Thanks, Kevin Facinelli Director of Operations Crystal Group Inc www.crystalpc.com 319-378-1636 x227 --- Sean Donelan <[email protected]> wrote: > > IBM is announcing several new servers today.
