Our servers are designed for Linux and have IPMI on the mainboard.

We support IPMI 1.5+SOL (serial-over-lan which really is a 2.0 feature),
so you can read sensor values, reboot, shutdown, boot up, and have access
to the serial console all through the management network which can be either
on a separate switch/vlan or on the same switch as your cluster network.
