John:
Have you thought of separating the databases? One for the reads and one for the write on different raids? Despite what some may believe this can be done.
Our goal is to create redundancy. We want either system to be able to work if the other is not available. Designating one database as a write db and the other as a read defeats that.
Thanks, Neil
