Speaking of temperature, I noticed a shiny new process cooler at the Orcon dc tonight, I expect all of us at the facility will have ice cold servers next week.
OK, I know you weren't expecting a serious reply to an off the cuff comment, but I can't help myself because this is so interesting (honest) I had assumed for decades that datacentres had to be cold because servers could not cope otherwise and so that meant air-con as a basic fitting. Then last year I read about the work done by BT in the UK on sustainable data centres, which basically means running them much hotter with fresh air cooling: http://globalservices.bt.com/LeafAction.do?Record=Sustainable_Data_Centres_c... and I also came across research that hard disks fail much more if they get too cool, though nowhere near as cool as you might imagine: http://labs.google.com/papers/disk_failures.pdf A general question then - is this (running hot computer rooms) already widespread in NZ?
