Abstract

A system for peer-to-peer vibration mitigation in a distributing computing system includes a secondary communication interface over which chassis management electronics (e.g., a chassis-level controller) and/or system storage nodes may initiate communications to in order to affect system changes that may decrease vibration-related performance degradation in the system.

Claims

1. A method comprising:

detecting vibration-related performance degradation;

initiating, in a first storage node, a communication over a drive operation interface to a second storage node in a distributed computing system, the communication requesting an action for decreasing vibration-related performance degradation in the first storage node.

2. The method of claim 1, wherein the drive operation interface is a physical interface that is separate from a primary data interface.

3. The method of claim 1, wherein the communication indicates a degree of vibration affecting the storage node.

4. The method of claim 1, wherein the communication includes a request that the second storage node modify its behavior to reduce the vibration-related performance degradation in the storage node.

5. The method of claim 1, wherein the action requested is performed by a processor in the second storage node without receiving an instruction from a host server.

6. The method of claim 1, wherein the communication includes directional aspects of the vibration-related performance degradation.

7. One or more non-transitory computer-readable storage media encoding computer-executable instructions for executing on a computer system a computer process, the computer process comprising:

detecting vibration-related performance degradation;

initiating, in a storage node, a communication over a drive operation interface to a chassis-level controller in a chassis of a distributed computing system, the communication requesting an action for decreasing vibration-related performance degradation in the storage node.

8. The one or more computer-readable storage media of claim 7, wherein the drive operation interface is a physical interface that is separate from a primary data interface.

9. The one or more computer-readable storage media of claim 7, wherein the communication indicates a degree of vibration affecting the storage node.

10. The one or more computer-readable storage media of claim 7, wherein the chassis-level controller transmits a request for a location-based corrective action for decreasing the vibration-related performance degradation in the storage node.

11. The one or more computer-readable storage media of claim 7, wherein the chassis-level controller alters the speed of a fan to decrease the vibration-related performance degradation in the storage node.

12. The one or more computer-readable storage media of claim 7, wherein the action requested is performed by the chassis level controller without receiving an instruction from a host server.

13. The one or more computer-readable storage media of claim 7, wherein the communication includes directional aspects of the vibration-related performance degradation.

14. A system comprising:

a drive operation interface for initiating a communication in a storage node of a plurality of storage nodes to an external component, wherein the drive operation interface is a physical interface that is separate from a primary data interface between the storage node and the external component, wherein the communication requests an action for decreasing vibration-related performance degradation in the storage node.

15. The system of claim 14, wherein the communication initiated in the storage node is communicated to at least one of another one of the plurality of storage nodes or a chassis-level controller.

16. The system of claim 14, wherein the communication indicates a degree of vibration affecting the storage node.

17. The system of claim 14, wherein the communication includes a request that another storage node modify its behavior to reduce the vibration-related performance degradation in the storage node.

18. The system of claim 14, wherein the communication is received by a chassis-level controller, and the chassis-level controller transmits a request for a location-based corrective action for decreasing the vibration-related performance degradation in the storage node.

19. The system of claim 14, wherein the communication includes directional aspects of the vibration-related performance degradation.
