In the Infrastructure Management department of a fair-size public transit company, I've been following the problems associated with IT growth for years, especially HVAC and power usage (including UPSes and emergency power generation). For some strange reason, I tended to view the problems at my company in isolation, when in fact they're a subset of universal problems and issues. It's astonishing how important IT has become. On a couple of occasions when our network went down, many almost had the feeling that there was no point in being at work. That PC terminal becomes the medium by which so much is done. A couple of years ago, for unusual reasons, we needed a typewriter, and nothing else would do. After days of searching, we unearthed a couple of old IBM Selectrics that hadn't been used or maintained for years. Almost immediately, we "let the smoke out" of them: the mechanics were completely gummed up with dried-out lubricants and dust. We had to go out and buy an electric typewriter. Not a big seller these days. And oh yes, a few miles of correction tape.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Your response to tech101 indicates the growing dependency on power, and the problems that come with that dependency. "The power utility will bend over backwards to get you as a customer and run new lines, etc., helping to maintain a good image by bringing new business to the local community, and improving its lot at the same time. But, once you're "in there" on a twenty-year lease, and after several years go by you find that you now require another 138 KVA to be pulled in, or a secondary or tertiary feed for redundancy and/or diversity to a branch off another grid? That's when the fun begins and the previous deal sweeteners suddenly don't taste so sweet anymore." The Dark Side of the deal."Another aspect we've not touched on, which I covered in earlier posts upstream, has to do with the unyieldingg Moore's Law-like densification of system hardware resulting in a doubling, sometimes tripling, of the amount of power being consumed per square foot as compared with only five or six years ago." All-optical is starting to look like our only salvation - because we're certainly not going to turn back. Another dated analysis, this one from Germany.iges.or.jp Jim
