I am not an architect but...

Aren't there two load values for a floor?  The one I think you are 
citing is the amount of weight which can safely be placed in a "small" 
floor area without punching through or causing other localized damage, 
the other is the total weight that can be placed on that floor without 
the building collapsing.  If the whole data center is on the ground 
floor sitting right on a concrete slab with no voids beneath it I would 
expect the latter value to be huge and not a real concern, but it might 
be less than (500 pounds per square foot) X (total area) on the 2nd or 
higher floors.
