Infrastructure Software

I struggle with the question why to use RAC when virtualization gives you the same benefits for less money. Or am I totally wrong.

I mean with virtualization you get, resource management, fail over and all that to a lower cost. "Consolidation of servers".

A couple of things that I can think of that RAC supplies such as load balancing, FAN etc are nice features but not vital to our needs.

Hoping for input from other forum member so that I can get this question cleared, or maby there is no such answer.
