Abstract: One embodiment of the present invention provides a distributed computer system comprising a group of nodes, said group of nodes having a first and a second node adapted to act as current monitor nodes, each node of the group of nodes having an identifier and a management layer being informed which node currently acts as the current monitor node. The first and second node each include a protocol server adapted to associate and to send an address to a node requesting an address in the group of nodes, and a memory adapted to store an association address-identifier of a node requesting an address. The protocol server is further capable of requesting the management layer of a node for an indication informing if said node acts as the current monitor node, and attributing, to the current monitor node, the ownership of a list of associations, said list comprising associations of the memory.

Abstract: A method and system of node location management in a distributed node system. A management server of a distributed node system includes a table manager, a node location manager, and a client manager. The table manager is adapted to load a first table including various information for node identifiers. The information includes: a location identifier, a hardware identifier, and configuration parameters. The node location manager is adapted to detect a new hardware identifier for a location identifier and to send a modification message to the table manager. The modification message comprises a new hardware identifier for a location identifier. Further, the table manager is adapted to update the first table responsive to a such modification message. The client manager is adapted to generate at least a second table in a client server according to the first table and to update the second table when the first table is updated.

Abstract: Locating nodes in a distributed computer system. The system comprises a switch having ports. The switch comprises agent code that is operable to report status of the ports and to identify a node coupled to the ports. The system also has a node coupled to the switch that has manager code. The manager code is operable to retrieve, from the switch, status of a port of the switch. The manager code is also operable to request, from the switch, an identifier of a node coupled to the port of the switch in response to status for the port meeting a condition. The manager code is further operable to maintain a table of data groups comprising port identifiers and identifiers of nodes coupled to the ports.
