ABSTRACT:
One embodiment disclosed relates to a high-availability cluster apparatus having a plurality of computing nodes and a hardware interface configured to connect to each of said nodes. The internode connections are coupled to the hardware interface to communicate node status signals between said nodes. A node is removable from being connected to the hardware interface without interrupting a topological continuity of the internode connections. Other embodiments are also disclosed.
