Method for managing a network of compute nodes

1. A method for managing a network of compute nodes interconnected by a plurality of interconnection devices, the method comprising:

organizing compute nodes into groups of compute nodes;

for each group of compute nodes, connecting interconnection devices interconnecting the compute nodes of the group to a group management node, wherein the group management node is dedicated to the group of compute nodes,

in each group management node, executing a management function through an implementation of independent management modules, wherein each management module for managing a management node is configured to communicate with other management modules of the same management node, wherein the communication between the management modules of the same management node is asynchronous, and wherein at least one group management node is connected to a level-2 management node, and

determining, by the at least one group management node, whether to transmit one or more messages to the level-2 management node based on processing of the one or more messages by the at least one group management node.

2. The method according to claim 1 , wherein the group management node is connected in an out-of-band mode to the interconnection devices.

3. The method according to claim 1 , wherein the management modules include:

a network topology management module,

a routing management module,

a network supervision module, and

a network performance measurement module.

4. The method according to claim 1 , wherein communications between the at least one group management node and the level-2 management node are accomplished in an out-of-band mode.

5. The method according to claim 1 , wherein a management node module processes the one or more messages received from at least one interconnection device to reduce quantity of data transmitted to the level-2 management node.

6. The method according to claim 3 , wherein the network topology management module is configured to maintain up-to-date a topology database and a status of each connector of each interconnection device.

7. The method according to claim 3 , wherein the routing management module is configured to calculate routing tables.

8. The method according to claim 3 , wherein the network supervision module is configured to manage messages transmitted by the interconnection devices and aggregate data produced by other management modules.

9. The method according to claim 8 , wherein the data is aggregated before transmitting the aggregated data to a level-2 management node.

10. The method according to claim 3 , wherein the network performance measurement module is configured to obtain and record data concerning a performance of the interconnection devices.

11. The method according to claim 10 , wherein the data concerning the performance of the interconnection devices includes a transmission rate in each port, number of packets, length of queues, number of errors, and protocols used.

12. The method of claim 1 , wherein the level-2 management node is connected to the at least one group management node via a switch.

13. The method of claim 1 , wherein the processing of the one or more messages includes determining a number of the one or more messages, the method further comprising:

determining, by the at least one group management node, not to transmit the one or more messages to the level-2 management node when the number of the one or more messages exceeds a predetermined threshold.

14. The method of claim 13 , wherein the one or more messages are received by the at least one group management node from one or more of the interconnection devices.

15. The method of claim 14 , wherein the level-2 management node is dedicated to a group of a plurality of group management nodes.

16. A non-transitory machine readable storage medium storing computer program instructions that, when executed, by a computer cause the computer to perform operations comprising:

executing, for a management node, a management function through an implementation of independent management modules;

communicating, by a management module of the management node, with other management modules of the same management node,

wherein the communication between the management module and the other management modules of the same management node is asynchronous,

wherein the management node is connected to a group of compute nodes via interconnection devices, and

wherein the management node is connected to a level-2 management node; and

determining by the management node, whether to transmit one or more messages to the level-2 management node based on processing of the one or more messages by the management node.

17. A system comprising:

a group of compute nodes;

interconnection devices connecting the group of compute nodes to a management node, wherein the management node is dedicated to the group of computer nodes; and

the management node, wherein the management node is configured to execute a management function through an implementation of independent management modules, wherein a management module for managing the management node is configured to communicate with other management modules of the same management node, wherein the communication between the management modules of the same management node is asynchronous, wherein the management node is connected to a level-2 management node, and wherein the management node determines whether to transmit one or more message to the level-2 management node based on processing of the one or more messages by the management node.
