Abstract

Real time provisioning and management of fabric-backplane enterprise servers includes monitoring system status and configuration, displaying monitoring results, accepting user commands, and providing hardware and software management and configuration commands to the system. In one embodiment, an event is generated when a pluggable module is inserted into the system. In response to the event, the availability of the pluggable module is displayed to a system operator, and the operator enters a command to provision a server that includes the pluggable module. The server provisioning command is processed, resulting in a hardware configuration command being issued to the system, and an event indicating a status associated with processing the command is returned. The recognition of the inserted module, the display to the operator, and the processing of the server provisioning command occur in real time.

Claims

1. A method comprising:

detecting a newly available compute element having multiple operating modes selected by included mode selection bits;

receiving a directive to form a compute system according to required compute system capabilities;

altering the bits according to the required capabilities; and

wherein the compute element comprises at least one partition of a plurality of physically partitionable symmetric multiprocessors, the at least one partition being formed at least in part by programmatically configuring links between processors of the physically partitionable symmetric multiprocessor to selectively isolate subsets of the processors with respect to respective shared memory coherency and cache coherency transactions on a link-by-link basis, the programmatic configuring of links comprising programming at least a portion of the included mode selection bits.

2. The method of claim 1, wherein the act of detecting is performed in real time.

3. The method of claim 1, wherein the act of detecting comprises determining capabilities of the compute element.

4. The method of claim 1, wherein the compute element is included in a pluggable module.

5. The method of claim 1, wherein:

the compute system is a first compute system; and

the act of detecting is responsive to releasing the compute element from a second compute system.

6. The method of claim 1, wherein the directive is provided by an automatic agent.

7. The method of claim 1, wherein the directive is provided by a human.

8. The method of claim 1, wherein the required compute system capabilities comprise required computing capabilities.

9. The method of claim 1, wherein the required compute system capabilities comprise required networking capabilities.

10. The method of claim 1, wherein the required compute system capabilities comprise required input/output capabilities.

11. The method of claim 1, wherein the required compute system capabilities comprise required storage capabilities.

12. The method of claim 1, wherein:

the compute element comprises operating mode control circuitry; and

the operating mode control circuitry is responsive to mode control bits derived from the mode selection bits.

13. The method of claim 1, further comprising executing an application program in part using resources of the compute element.

14. The method of claim 1, further comprising monitoring the compute system to detect status changes according to monitored items.

15. The method of claim 14, further comprising notifying an agent of the detected status changes.

16. The method of claim 15, wherein the monitored items include a count of partitions in the compute system.

17. The method of claim 15, wherein the agent is a human.

18. The method of claim 15, wherein the agent is a program.

19. A system comprising:

a compute element having multiple operating modes;

a detection circuit to detect availability of the compute element;

a management software execution circuit executing management software;

the management software having functions comprising

receiving a directive to form a compute system according to required compute system capabilities, and

altering mode selection bits included in the compute element according to the required capabilities; and

wherein the compute element comprises at least one partition of a plurality of physically partitionable symmetric multiprocessors, the at least one partition being formed at least in part by programmatically configuring links between processors of the physically partitionable symmetric multiprocessor to selectively isolate subsets of the processors with respect to respective shared memory coherency and cache coherency transactions on a link-by-link basis, the programmatic configuring of links comprising programming at least a portion of the included mode selection bits.

20. The system of claim 19, wherein the detection circuit operates in real time.
