potentially wasting it through inefficient IT processes. At a recent
LINX meeting Lex Coors of Interxion mentioned that they had UPSes from
two different suppliers and while it was difficult to measure the
efficiency of each they were surprised to discover how inefficient one
manufacturer was compared to another.

The worst offenders are the HVAC units, but only due to poor designs by the people planning and building the DC's and server rooms in the first place, how many here actually expel the hot air via a rack chimney system into an overhead plenum (being the air intake for the HVACs) not many I bet, most I've seen use hot/cold aisle, so the hot air still goes back into the same DC your trying to keep cool, that's far from efficient in this day and age.<BR>
