Ok, your data center kind of blows mine away.
And the other image you posted was really nice.
However, for those of us without under floor cooling,
and with more than one rack,
I was wondering if lining up the racks,
having ducts push cold air down the front of the racks where the fan
intakes on most equipment seem to be,
and ducts sucking the hot air up the back of the racks where the fan
exhausts on most equipment seem to be,
would be a good solution?
Possibly with alternative air conditioning to the room to not only control
the overall room but to also back up the other unit in case of unit
Granted, you'd have to have those deep racks that would allow air flow
down front and back.
