Whats the recommended ive version for SA4500 cluster?
We run 6.2 at the moment in testing environement.
Are there any good arguments to use 6.3?
That is a difficult question. It depens on you situation. Check the release notes for fixed and know issues. Maybey also the supported systems.
Currently I am a happy 6.3 user
Running 6.3R2 in production on 10 SA6000s. No issues.
6.3 adds integration with NSM 2008.
