I asked a day or so ago whether you were ignorant or just didn't like RAC: You just answered the question.

The entire point of RAC is to NOT to buy hardware with HA features. You have entirely missed the point of RAC. Not just by a few inches but by a few tens of kilometers.

RAC is not about dual power supplies and such. It is about low cost hardware. If something goes wrong you want the server to fall over. The other nodes in the cluster, load balanced, pick up the processing. A typical 2 CPU node for a RAC cluster is less than $5000 USD. If you are spending more than that you need to go find your Oracle salesperson and check into a re-education camp.
