Abstract

A server rack includes a power mapping module, a power receptacle that includes a power tine communication module wherein the power receptacle is uniquely associated with a rack unit of the server rack and is collocated with the associated rack unit, and a server coupled to the power mapping module via a management network, wherein the server asserts an interrupt request to the power mapping module via the management network. The power mapping module sends a unique identifier via the first power tine communication module in response to receiving the interrupt request. The server receives the unique identifier via the second power line communication module and sends the unique identifier to the power mapping module via the management network. The power mapping module determines that the server is installed into the rack based upon the receipt of the unique identifier.

Claims

1. A server rack comprising:

a power mapping module;

a power receptacle coupled to the power mapping module and including a first power line communication module, wherein the power receptacle is;

uniquely associated with a rack unit of the server rack; and

collocated with the associated rack unit; and

a server installed into the rack unit and including a second power line communication module, the server being coupled to the power mapping module via a management network, wherein the server asserts an interrupt request to the power mapping module via the management network;

wherein;

the power mapping module sends a unique identifier via the first power line communication module in response to receiving the interrupt request;

the server receives the unique identifier via the second power line communication module and sends the unique identifier to the power mapping module via the management network; and

the power mapping module determines that the server is installed into the rack based upon the receipt of the unique identifier.

2. The server rack of claim 1, wherein the power mapping module determines a physical location of the server based upon the power receptacle being collocated with the rack unit.

3. The server rack of claim 2, wherein:

the management network includes a data center management controller; and

the power mapping module further provides the physical location of the server to the data center management controller.

4. The server rack of claim 1, further comprising:

a power distribution unit, wherein the power mapping module and the power receptacle are integrated with the power distribution unit.

5. The server rack of claim 1, wherein the server includes a management controller coupled to the second power line communication module.

6. The server rack of claim 5, wherein the management controller is operable to manage the server via the second power line communication module.

7. The server rack of claim 1, wherein the server acknowledges the receipt of the unique identifier via the second power line communication module.

8. A server rack comprising:

a power mapping module;

a power receptacle coupled to the power mapping module and including a first power line communication module, wherein the power receptacle is;

uniquely associated with a rack unit of the server rack; and

collocated with the associated rack unit; and

a server installed into the rack unit and including a second power line communication module, the server being coupled to the power mapping module via a management network, wherein the server asserts an interrupt request to the power mapping module via the management network;

wherein;

the power mapping module sends a unique identifier to the server via the management network in response to receiving the interrupt request;

the server receives the unique identifier and sends the unique identifier to the power mapping module via the second power line communication module; and

the power mapping module determines that the server is installed into the rack based upon the receipt of the unique identifier.

9. The server rack of claim 8, wherein the power mapping module determines a physical location of the server based upon the power receptacle being collocated with the rack unit.

10. The server rack of claim 9, wherein:

the management network includes a data center management controller; and

the power mapping module further provides the physical location of the server to the data center management controller.

11. The server rack of claim 8, further comprising:

a power distribution unit, wherein the power mapping module and the power receptacle are integrated with the power distribution unit.

12. The server rack of claim 8, wherein the server acknowledges the receipt of the unique identifier via, the second power line communication module.

13. The server rack of claim 8, wherein the server includes a management controller coupled to the second power line communication module.

14. The server rack of claim 13, wherein the management controller is operable to manage the server via the second power line communication module.

15. A server rack comprising:

a power mapping module;

a power receptacle coupled to the power mapping module and including a first power line communication module, wherein the power receptacle is;

uniquely associated with a rack unit of the server rack; and

collocated with the associated rack unit; and

a server installed into the rack unit and including a second power line communication module, the server being coupled to the power mapping module via a management network, wherein the server;

sends a unique identifier to the power mapping module via the management network; and

sends the unique identifier to the power mapping module via the second power line communication module;

wherein the power mapping module determines that the server is installed into the rack based upon the receipt of the unique identifier via the management network and the second power line communication module.

16. The server rack of claim 15, wherein the power mapping module determines a physical location of the server based upon the power receptacle being collocate with the rack unit.

17. The server rack of claim 16, wherein:

the management network includes a data center management controller; and

the power mapping module further provides the physical location of the server to the data center management controller.

18. The server rack of claim 15, further comprising:

a power distribution unit, wherein the power mapping module and the power receptacle are integrated with the power distribution unit.

19. The server rack of claim 15, wherein the server acknowledges the receipt of the unique identifier via the second power line communication module.

20. The server rack of claim 15, wherein the server includes a management controller coupled to the second power line communication module.
