Any OS flavor will allow for all of these, including RHEL.  I'm not sure
how RHEL prevents any of this.

I'd really like to be sold on the latest 3.x kernel scheduler, but I am
not sure that it would provide a significant performance improvement for
a loaded compute node.

I like having a local team.  But I like backing them up, too.  When they
hit a weird hardware error or performance problem, they should be able
to call an expert systems engineer that has the aggregate experience
from many deployments.
