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!
