Thus spake ip dude <[email protected]>: > Hello NANOG group. I am trying to make a case for using DC power > supplies versus AC power supplies for typical IP networking > equipment. Is there any published whitepapers detailing this subject? > Do you have any suggestions to aide my argument? Most of the argument depends on the facility you're in. Assuming you're asking as an end-customer: DC requires clue from your staff when installing/removing equipment, and this means safety training at a minimum. Power choice also affects your equipment purchasing: DC versions of gear are often priced higher, and gear not intended for telcos/ISPs may not have a DC option available at all. OTOH, many colos -- especially ones run by telcos -- don't provide AC UPS. If you want AC UPS in these environments, you'll have to provide your own, which is expensive, bulky, and a maintainance burden. If you're building your own datacenter, please specify that and I'm sure you'll get a whole different discussion :) S
