We set everything atop IsoBase isolation platforms, which
can move up to 8 inches in any lateral direction, letting
the floor move under the equipment racks.

No other bracing is used, and each row of cabinents are
bolted together such that a single rack can't topple,
and the whole row of gear "floats" over the floor.
