I have been pretty heads down over the last few days. We
gather/store/generate most of this information (apart from serial number
which is in general, quite hard for random hardware). We store it in a
SQLite database, and use a combination of web clients and command line
clients to interact with it, presenting the output to our users.
For IPMI and related per node elements, upon post-installation, our
units run something called a finishing script, which queries the BMC
hardware, gathering the IPMI mac address (if available), and using a
remote web client, storing that back into the database if requested. We
configure, actually derive the IPMI address from the network address
using a simple algorithm, which the finishing script handles. It
configures the BMC for us upon completion, and commits the
configuration. This has worked on a fairly wide range of hardware thus
far, though some BMCs behave quite differently from others.
This capability is generally part of our cluster loads. Distro and
for the most part, hardware independent; as long as we can talk
to/control/set the BMC from a script, we can make this part of the stand

AT is built for a more general problem. You can certainly use it, or
any other system you wish. What we have is tied into our cluster
setup/load system, so it is more cluster specific than the others.
