The tiles intended for cold air flow have lots of little 1/4" or so holes
in them that a roll of tape can't fall through. The roll of tape *can*
escape through the 6x6 cable cutout under the rack if there aren't too
many cables in the way. If we had overhead cabling and under-floor cooling,
we'd have no large cutouts anyplace. :)
(Alas, the data center across the hall is 27 years old, and we'll need to
build a new one to fix it. Someday soon, maybe. :)
