Power-Control Hardware
- Sometimes a cluster node needs to reboot another cluster node, in order to
assure that the service is only running on a single cluster node.
- One way to achieve this is using network-controlled power supplies,
- Another way is using remote console hardware that is bundled inside
modern server machines
- - which allows you to turn off the server machine even if the server's
operating system is hung.
