Dell Embedded Server Management support

Contributed by mk/reverse on from the self-monitoring-hardware dept.

marco@ just wrote misc@ about the recently added support for Dell's Embedded Server Management via esm(4)
Folks who keep track of cvs changes might have noticed that new a device has
been introduced called esm(4).  ESM, Embedded Server Management, is a Dell
specific server management protocol for 4th and 5th generation servers (e.g.
2450, 2500 etc).  It's in essence what later became IPMI which we also support
via ipmi(4).

This is very cool stuff that provides sensors for monitoring e.g. temperature, fan speeds and voltage levels that all are available via sysctl(3) and sensorsd(8). Another cool feature is that this will also enable the watchdog(4) available on the hardware which may save administrators many long drives outside working hours.

Read the full message and give -current or snapshots a spin on any compatible Dell hardware you have available.

    I never worked with a Dell machine, but I really like the new IPMI/ESM framework.

    Thank you, developpers!

    Is IPMI implemented fully enough to remotely reset it via the LAN interface ? Extremely useful for those system hangs.

      We now have watchdog(4) support so in essence yes.
