We use xCAT some.  Wake Forest University is a big IBM partner, and
large parts of xCAT were designed for IBM clusters/servers.  You can do
things like

 rpower <group> off
 dsh <group> command

There are perhaps some provisions for doing remote BIOS updates, too,
and--to be more general--remote boots to arbitrary kernel images.

I decided to stop using xCAT in favor of my own
PXE/DHCP/kickstart/cfengine environment.  xCAT is mainly proprietary,
and one guy--Egan Ford--does most of the work on the project.

Yours,
John
