From: "Kevin Stange" <kevin () steadfast net>People are still feeding their gear with AC? Save on PS inefficiency, and feed direct 12/5vDC to the servers. Save space, save power, save cooling.If you're already in a datacenter, getting 208V AC from an existing AC infrastructure is a lot easier, cheaper, and sometimes more plausible than building a DC plant. If you have your own facility, it's a different story, but if you do colo, you probably have more customers expecting AC than DC, so you'll at least need to maintain both infrastructure.
It *is* Friday night, Kevin. :-) He said 12/5VDC, not -48. Cheers, -- jra
