One thing to point out here is that there are a lot of "servers" in high end
data centers that do not have UPS backup. Those racks full of 1U and 2U
boxes that are used to make "grids", "clouds" and so on often are built with
as much gear as you can stuff in a rack - no batteries or UPS to be seen, so
they are really quite similar to the normal desktop or home systems that we
normally run at home :-)
These days even bargain basement data centers provide UPS functionality for
you, via generator backup and A/B power.
