I have looked further into this and it does appear that many of the UKs top colocators have similar deals with only 0.5A per 1U. Its a ridiculously low amount of power for any modern server, because I can't find a single one (despite how slow you go) that gets remotely that low. About the best I can find is a 1Ghz Pentium 3 with 512MB of RAM on Scan (£350!) that manages to go as low as 240watts. That is still double the power usage your targeting and its a zillion years old.
I do remember when I was last putting in boxes into a rack at Telecity (Docklands London) that we couldn't fill every slot because of power constraints, and I think we got a maximum of 32Amps for 32U cabinet there. That is double what most colocators are offering and still half of what realistically is needed. I know a lot of data centres don't like blades as the power density is high and from IBM you can get 14 blades (that's upto 28 CPUs, 56 cores with an E series) in 7U. The power usage as far as I can tell is a modest 2000 W (8.3 Amps). That is just under 1.2 Amps per blade, which is closer than most of the 1U servers but still far in excess of fitting into 0.5A. There is something I'm missing here because whatever way I look at it I can't see 0.5A being remotely doable. I've asked some questions of some colleges who do this sort of thing more often, will get back to you in a day or so. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Deploying Rails" group.
