A good data center is loud enough that no one can hear that. :)

I've run lots of (heavy) 6/4 SOOW power cord on overhead cable trays, and
it is a pain, but it's way easier than pulling up half of the tiles in a
data center to figure out where the cable you're trying to pull is tangled,
just to find it stuck barely out of reach under the middle of some
production equipment.

An acceptable compromise is something like the 6 ft raised floor they have
over at NCSA.  But the typical 12" raised floors I've had to deal with
are... unpleasant.
