I don't think so :-)
At one point we had 24 nodes participating in an mnesia schema. It
used to work quite well. The only problem was that recovering from
partitioned networks was a bit of a pain. Eventually we got fed up and
bought a slightly bigger machine. Now, the entire database fits in two
erlang nodes running on the same box (we needed two nodes because of
the 4GB limit).
But now with 64 bit erlang, I'm getting rid of this scheme as well and
putting the entire database in a single erlang node with 128 fragments
for the customer table. It's amazing how much memory you can get on a
single blade server these days.
