Yes, it is a very useful device. It should be what is called by Dell
'iDRAC Express', because in such case, the BMC port is shared with the
LAN port. If you have the 'Enterprise' version, there is a dedicated
port. Certainly someone changed the default behaviour, because by
default, iDRAC Express has a fixed IP, something like 192.168.1.120.
As you can remote power off the server, it seems it can be used also as
fencing device, in a virtualisation cluster with HA, even if I did not
try myself.
