What combination to select for Oracle RAC on IBM Pseries?

This is infact a frequently asked question by my customers. They all seem confused by all possible combinations for building Oracle RAC clusters on pseries servers.

I decided to summarize all these possible options. In one of my coming posts , i will try to summarize pros and cons for each possible combination.
