Again a lack of personal experience with RAC.

Again a lack of personal experience with RAC.

What comes through very strongly from your statements about NUMA is that you don't understand what RAC is, why RAC is the most compelling HA solution, and have missed Oracle's message around RAC.

NUMA is incapable of providing 80% of the value of a RAC cluster.
