Even if you go for Vertas Storage Foundation for RAC, you still need to
use CRS stack from 10g onwards. So, you will have two clusterwares running
and I don't prefer that way.
I have a client running VCS + CRS + 4node RAC. I can tell you, in case of
failures, it is very hard to understand who initiated the issue.
I think, my preference is to keep it simple: ASM + RAC + CRS stack.
And Yes, we administer CRS stack.
