There is a site on Dell - Hardware Monitoring, as well as a wiki with instruction on how to setup their OMSA tooling using yum or up2date.
[update]My first update for their instructions:
- be sure your server has Internet access, as most servers will use a proxy or so.
- use export http_proxy=http://yourproxy.example.com:port to configure it just for the session,
- and setup up2date to use an HTTP proxy by editing the settings in /etc/sysconfig/rhn/up2date.
