Yeah, but then what happens when that one machine crashes or needs to
You just lost 32 gigs of your cache. Unless you are like facebook and
have 200 of these machines, replacing a dozen small nodes with one large
one doesn't always make sense.
I believe LiveJournal tried this a long time ago, and found the failure
of one super large machine was enough to overload their DB machines.....
