Re: [SAGE] shipping rack servers

I'd assume, in some cases, rolling them could distribute weight to fewer
tiles than you would normally have the rack/cage sitting on.  (Maybe you
set the cages on intersections of 4 tiles, or across 2)

Most tiles have crush weight ratings, where the tile itself can collapse.
Another thing to keep in mind is the underlying structure, that also has
weight ratings.
