I'm not debating which database scales better. I'm questioning why anyone would use a "big" server for mysql. If you're going to do replication with mysql, you don't need 10 servers with 68 gigs of memory -- you'd probably be better off with 100 servers with 4 gigs of memory. However, if you're going to go with "big" database servers, one should use Oracle or PostgreSQL since they can actually make use of the memory & cpu cores.
