HP ProLiant Cluster + RHEL AS 3.0

[Chris Purcell]

We've been thinking about purchasing an HP ProLiant DL380 Packaged Cluster
(using shared storage) and running RHEL AS 3.0 on it.  Has anyone ever
done this before (or something similar) with RHEL 3.0?  If so, does
everything run okay on this hardware?

I'd like to hear about what kind of clusters some of you are running out
there with RHEL 3.0 (hardware and the purpose of the cluster).

Thanks,
Chris
