Agreed - we do the same here at VLSCI.   Having UPS for our IBM
systems (iDataplex and BlueGene/Q) wouldn't make sense given our power
around here is pretty good (touch wood) and would have had a sizeable
impact on the cost of the data centre to house them. However, all our
storage and infrastructure stuff like management node, etc, are on UPS.

Our SGI cluster though is on UPS, it's in a different data centre
where all racks are on UPS (DRUPS in this case) and there is no
non-protected option.

cheers!
