You can almost date a DC by the power/cooling limits per rack.  The
older style DCs pre-date blade chassis where 4RU or mor servers were the
norm so the density wasn't an issue. The middle ones can take one or two
blades per rack and then you're onto modern set.

The newer DCs are going more into the POD arrangements or other clever
physical topologies to help with getting the cooling sorted. In some
situations the cooling is THE limit to worry about.
