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.
