There are some articles in Wired on the new Facebook data centers that are doing 208V to 48V with batteries in 1 out of each 7 or 8 racks.
They seem to be designing their data centers from scratch, power, cooking, cabinetry, CPU boards, etc, etc. 48V equipment as I remember historically came from the telco industry (because they used 48V battery banks I guess). They didn't do UPSes, because they ran everything from batteries, and just used commercial power to charge the batteries. Things may be different now.
