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.
Claims22
A high-availability cluster apparatus, the apparatus comprising:
- a plurality of computing nodes of said cluster;
- a hardware interface configured to connect to each of said nodes;
- and
- internode connections coupled to the hardware interface to communicate node status signals between said nodes,
- wherein a node is removable from being connected to the hardware interface without interrupting a topological continuity of the internode connections.
A method of communicating a node status signal between nodes of a high-availability computing cluster, the method comprising:
- receiving the node status signal from a first node by a first connector on a hardware interface;
- forwarding the node status signal from the first connector to a second connector on the hardware interface;
- and
- transmitting the node status signal from the second connector to a second node.
A hardware interface configured to communicate a node status signal between nodes of a high-availability computing cluster, the hardware interface comprising:
- a plurality of connectors, each connector configured to communicate the node status signal with a corresponding node;
- and
- internode connections configured to transmit the node status signal between the connectors in a point-to-point loop configuration.
