For DSU to work you need an OS with the Lifecycle controller you are 
independent of the OS.  At our site we download all the firmware updates 
from the dell support site and  copy then to our stepping stone server. 
The firmware updates are done by a program called "recite":
  * http://de.community.dell.com/techcenter/w/wiki/285.recite

For our cluster we have all kind of recite scripts. So we can control 
bios/network/raid-level/idrac settings and do firmware upgrades.

This project has been abandoned by Dell in favor of the industry standard:

Currently redfish is too limited. It can not do firmware updates ;-(
