that's local ipmi, which to me is quite beside the point. ipmi is valuable
primarily for its out-of-band-ness - that is, you can get to it when
the host is off or wedged.

on our dl145's, we don't normally have local ipmi enabled at all,

modprobe ipmi_devintf;modprobe ipmi_si
loads it, which can be useful for something like
ipmitool user set password 3 foobar
ipmitool mc reset

IMO, proprietary tools are evil. using them encourages vendors to
diverge from open standards and hurts everyone, and in the long-term.
demand standards and just say "no" to non-standards, especially when
venors claim that they're supra-standard features. if we as computer
people have learned anything at all from our own history,
it is that open standards drive everything in the end.
