RAC and Sun cluster
We are installing 5 Sun Solaris servers (T2000's) for Oracle databases(no applications) in a RAC environment on EMC disk drives. The argument has come up as to whether using the Sun Cluster v3.2 is necessary when RAC is installed. One group states that the Sun Clustering complicates the environment, while the other group states that complete data integrity is ensured with both the Cluster and RAC environment. I know this may open a can of worms...but...I would like to see arguments for both sides of this debate.
Thank you in Advance.....

Have you bench marked RAC performance on the T2000 ? I was told by a sun rep. that they aren’t really suitable for RAC because of the CPU architecture. I’ve also read of a few people having performance issues with such a set up.
Personally, I would go with pure RAC set up, particularly now 11G is out. I think it just overcomplicates it and also a big thing to consider is Oracle have stopped certifying third party cluster systems.

From previous research and experience It’s my understanding that the T2000 are good for thread applications but not good for heavy IO applications. ( webserver/email/servers)
I also would recommend a pure RAC setup.
