I'm surprised to hear that. Normally storage is the bottleneck for a database, i.e. you would not gain performance if more than one database ran against the same storage. > Another option is Oracle which can do that. I have not heard that RAC is a performance booster. It's more like a protection against certain types of hardware failure.
