If you are using mysql to store accounting and auth data the best solution is to have mysql cluster which is high available shared nothing DB (no need for any kind of shared storage ) with high performance ( 1 billion transaction as claimed ny oracle for the new version 7.2.4). By the way there is a white paper on using freeradiu with mysql cluster, you can find it in mysql website.
