You Mileage May Vary

I'm have been very happy with IPMI, and find it quite dependable.

As an aside, is this an IPMI interface which piggybacks on an ethernet
(ie there is an internal bridge)
There is a known issue which I uncovered, where the ports used by IPMI
can clash with ports used by the main machine.

There is a sysctl you can set: sunrpc.min_resvport
Set this to  be higher than the IPMI ports
