Abstract

Dynamically configuring a storage system to facilitate independent scaling of resources, including: detecting a change to a topology of the storage system consisting of different sets of blades configured within one of a plurality of chassis; and reconfiguring the storage system to change an allocation of resources to one or more authorities responsive to detecting the change to the topology of the storage system.

Claims

1. A method of dynamically configuring a storage system to facilitate independent scaling of resources, the method comprising:

detecting a change to a topology of the storage system consisting of different sets of blades configured within one of a plurality of chassis; and

reconfiguring the storage system to change an allocation of resources to one or more authorities responsive to detecting the change to the topology of the storage system.

2. The method of claim 1, further comprising:

executing an authority on a first set of blades; and

wherein reconfiguring the storage system further comprises executing the authority on a second set of blades.

3. The method of claim 1, further comprising:

associating storage on a first set of blades with a write group; and

wherein reconfiguring the storage system further comprises associating, in dependence upon a write group formation policy, storage on a second set of blades with the write group.

4. The method of claim 1 wherein:

detecting the change to the topology of the storage system further comprises detecting that an amount of processing resources within the storage system has changed; and

reconfiguring the storage system further comprises increasing or decreasing an amount of processing resources allocated to one or more authorities.

5. The method of claim 1 wherein:

detecting the change to the topology of the storage system further comprises detecting that an amount of storage resources within the storage system has changed; and

reconfiguring the storage system further comprises increasing or decreasing an amount of storage associated with one or more write groups.

6. The method of claim 1 wherein detecting the change to the topology of the storage system further comprises detecting that a utilization of a particular resource has reached a utilization threshold.

7. The method of claim 1 wherein an authority executing on compute resources within a first blade causes data to be stored on compute resources within a second blade.

8. An apparatus for dynamically configuring a storage system to facilitate independent scaling of resources, the apparatus including a computer processor and a computer memory, the computer memory including computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

detecting a change to a topology of the storage system consisting of different sets of blades configured within one of a plurality of chassis; and

reconfiguring the storage system to change an allocation of resources to one or more authorities responsive to detecting the change to the topology of the storage system.

9. The apparatus of claim 8 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of:

executing an authority on a first set of blades; and

wherein reconfiguring the storage system further comprises executing the authority on a second set of blades.

10. The apparatus of claim 8 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of:

associating storage on a first set of blades with a write group; and

wherein reconfiguring the storage system further comprises associating, in dependence upon a write group formation policy, storage on a second set of blades with the write group.

11. The apparatus of claim 8 wherein:

detecting the change to the topology of the storage system further comprises detecting that an amount of processing resources within the storage system has changed; and

reconfiguring the storage system further comprises increasing or decreasing an amount of processing resources allocated to one or more authorities.

12. The apparatus of claim 8 wherein:

detecting the change to the topology of the storage system further comprises detecting that an amount of storage resources within the storage system has changed; and

reconfiguring the storage system further comprises increasing or decreasing an amount of storage associated with one or more write groups.

13. The apparatus of claim 8 wherein detecting the change to the topology of the storage system further comprises detecting that a utilization of a particular resource has reached a utilization threshold.

14. The apparatus of claim 8 wherein an authority executing on compute resources within a first blade causes data to be stored on compute resources within a second blade.

15. A computer program product for dynamically configuring a storage system to facilitate independent scaling of resources, the computer program product disposed on a non-transitory storage medium, the computer program product including computer program instructions that, when executed by a computer, cause the computer to carry out the steps of:

detecting a change to a topology of the storage system consisting of different sets of blades configured within one of a plurality of chassis; and

reconfiguring the storage system to change an allocation of resources to one or more authorities responsive to detecting the change to the topology of the storage system.

16. The computer program product of claim of 15 further comprising computer program instructions that, when executed by the computer, cause the computer to carry out the step of:

executing an authority on a first set of blades; and

wherein reconfiguring the storage system further comprises executing the authority on a second set of blades.

17. The computer program product of claim of 15 further comprising computer program instructions that, when executed by the computer, cause the computer to carry out the step of:

associating storage on a first set of blades with a write group; and

wherein reconfiguring the storage system further comprises associating, in dependence upon a write group formation policy, storage on a second set of blades with the write group.

18. The computer program product of claim of 15 wherein:

detecting the change to the topology of the storage system further comprises detecting that an amount of processing resources within the storage system has changed; and

reconfiguring the storage system further comprises increasing or decreasing an amount of processing resources allocated to one or more authorities.

19. The computer program product of claim of 15 wherein:

detecting the change to the topology of the storage system further comprises detecting that an amount of storage resources within the storage system has changed; and

reconfiguring the storage system further comprises increasing or decreasing an amount of storage associated with one or more write groups.

20. The computer program product of claim of 15 wherein detecting the change to the topology of the storage system further comprises detecting that a utilization of a particular resource has reached a utilization threshold.
