One way that HP plans to combat heat

Alan pointed me to this article earlier today. Assuming I've read this article correctly, the summary is this: in order to combat heat in the data centre, HP is going to sell a water-cooling system which will allow you to dump 30 kilowatts of heat out of a single rack. Is it just me, or does that seem a little short-sighted, treating a symptom rather than the cause.... If it was my money being poured into the data centre, I'd want the most space- and heat-efficient servers possible, like the Sun Fire T2000, rather than just spending more money on 32bit x86 architecture systems. Incidentally, I first heard of the CoolThreads architecture at an internal Sun conference in 2001. As I recall it, the tagline from the presentation was "all the power of an E10k, on a single chip." At the time I thought that this would be incredibly expensive to achieve and I did have my doubts. There are times when I love to be wrong; CoolThreads is one of those. Hmmmmmmm. I wonder whether I can convince my better half that I need one for home ..... :-D
