I visited the Dreamworks DC in SOCAL back in 2005 and they had per rack isolation plates as you remember. They also had a 25' long tape drive on one huge isolation plate. Those plates basically are on a central piston and rotate in a circular pattern. Seems a lot cheaper than proofing the entire floor.
