    How many 11gR2 RAC instance servers would be needed?

    888748
      On the shared SAN drive - there will be as many as 6 11gR2 databases. For 2 node RAC instance servers - how many instance servers would work fine - are two separate servers needed for each database?

          ??? That depends. Does each database require high availability? Your question seems to indicate a lack of understanding of what RAC provides and how it achieves that goal... High Availability.

          RAC can also be used to provide additional horsepower - on the fly. I have added a new node - start to finish in < 2hrs. (new hardware+install/configure OS+addnode to RAC and have it online and operational.) No other database solution offers this flexability.
