[AusNOG] CNET: Google uncloaks once-secret server

[Bob Purdon]

Battery goes directly into the PSU, so presumably there's a charging
circuit in there.  I'd expect this to work a lot like a 48VDC system,
except at 12V.

The only thing that isn't explained - at least for me - is where they're
getting the 5V for the HDD's from (assuming the Hitachi Deskstar's
actually require 5V).  They may have a small DC/DC converter under the
HDD's for that though.
