I run a very busy PG installation on one.

With the price of GigE adapters I wouldn't consider anything else.
I have a huge database that takes about an hour to copy. The netApp snapshot
feature is very nice because I can get a "moment in time" image of the
database. Even though I can't run from the snapshot because it is read only
(*) and PG needs to write to files just to open the database, I can copy it
and get a runnable version of the DB. If I copy directly from the original I
can get many changes while copying and wind up with a copy that will not run.
(*): It would be nice if PG had a flag that allowed a database to be opened in
read only mode without touching anything in the directory.
