Slightly less efficient on a per-server basis, but still pretty darn good. Tom,

Just to revisit this issue from last year…we’re now up to 900,000 wikis hosted on a total of 67 servers. Slightly less efficient on a per-server basis, but still pretty darn good.

Most of the energy growth at Caltech over the last few years, and the projected growth going forward, is high performance computing. We most definitely want to know if an off-site virtualized solution (ie cloud computing) is better than our own server rooms (highly likely that it is), and most importantly, how much better? We need to be able to go a faculty member and offer them the chance to trade out to an off-site solution, and know how much energy this will save. This is a big issue for universities, too.

Watson Thu, 29 May 2008 15:36:30 +0000 http://greenmonk.net/?p=170#comment-3350 Seems like an awfully complicated one to tackle. Systems like Amazon EC2 likely keep servers hot so they can be quickly made available to users. So there could be many servers doing nothing useful but consuming electricity and generating heat. On the other hand that kind of system can probably be better optimised than if the servers were spread amongst many companies. Also a small company could power down servers over weekends when they are not used. But if they were using PbWiki the server wouldn't be powered down (shared or not.) Awfully complicated I'd say.
