We use them all the time as well, and it has to be said, they are
flaky as hell.
Sometimes commands work, sometimes they don't. Currently we have
about 5 IPMI cards we can't communicate with. Another couple we
can't get on the web interface with but can issue commands to using
FreeIPMI.
Their inability to function correctly really becomes apparent when
you loose your water chiller and your automated process starts
issuing power-off commands... and then when you get in, you discover
that some nodes are still up and your machine room is really really hot.
Having said that, we have yet another bios update to apply... perhaps
they will work correctly after we get it on?
Chris, I use Supermicro IPMI all the time.
Working with it today, actually.
They can do what you ask - power control, access to the BIOS via a
serial console etc.
They have a choice of either 'piggybacking' on the first on-board NIC,
or of using a separate mini-USB style cable and a separate port which
clips into the rear of the server.
We tend to use the 'piggyback' variety.
