Maybe a first step is to load-balance the java processing on many CPUs,
and let only one machine run the database, and another one the DB cache
(or a JDBC 3T) if you need external cache.
Today the main problem with large architectures is not on the database
side first, but rather on JVM's speed & stability.
And RDBMS vendors have solutions for very large data stores.
This still lets you the choice to run servlets on cheap boxes or big SMP
machines.
That's something to be tried first IMO.
Let us know if you find something better.
