First, I would strongly recommend against using RH9 in a production 
environment. It is a short-life-cycle product meant for hobbyist desktops.
More than that, it was a way to beta test some pretty radical OS changes 
on the masses before their inclusion into RHEL3.

Secondly, if you are going to use Opteron there are very good reasons to 
use SuSE Enterprise Linux (SLES) instead of RH9. SLES natively supports 
the Opteron while RH9 will only run in 32-bit mode. SLES also has a 
5 or so year lifespan, versus the 1 year on RH9. SLES has preconfigured
NUMA support for the Opteron.

If you wait another month, the RedHat Enterprise Linux (RHEL) version 3
will be out and has the same benefits as SLES.
