Re: RAC h/w basic costs

I would add one very strong recommendation -

It might make the numbers less attractive, but if you're considering a
move to RAC then you absolutely should plan for a minimum of two cluster
databases - one for testing/development and one for production.  It's a
really bad idea to plan on testing only with non-RAC systems.  Make sure
to include that in your hardware planning.  Also consider licensing.
