Well, it depends on what you're trying to do, if it's get
the system and CPU temperatures then a PDU
using lm_sensors is a poor substitute for IPMI.
IMHO the only disadvantage of lm_sensors is the poroblem of building of right
sensors.conf file.
well, there's the little matter of being able to get data when
the node is crashed, offline, busy, etc. I also very much like
the ability to quer

I have only seen a handful of different IPMI interfaces, but they all
were reasonably reliable.

IPMI normally provides all the motherboard's sensors as well. it

Why?
If nodes shutdown, on commands from the scheduler, that is good.
And, if they do not, how is cutting power by the PDU socket

Indeed, but getting it working and calibrated can be,
umm, interesting..

If you wanted it stacked that way (performance order), then this

Notice how the performance ramp is pretty close to identical to
