Abstract

Claims (39)

1 . A storage system, comprising:

a primary storage node having a processor and memory storing scheduling logic; and

a plurality of secondary storage nodes operatively coupled to the primary storage node, each of the secondary storage nodes having a processor and removable solid state storage memory, wherein the processor of the primary storage node when executing the scheduling logic is configured to:

assign a priority to tasks executed by the storage system;

monitor a processing load of the storage system;

monitor a storage capacity of the storage system; and

adjust power consumption of a processor of at least one of the plurality of secondary storage nodes based on the priority of tasks being executed by the storage system and the processing load and the capacity of the storage system.

2 . The storage system of claim 1 , wherein to adjust power consumption comprises:

reducing one of a frequency or a clock speed for operation of the processor of the at least one of the plurality of secondary storage nodes.

3 . The storage system of claim 1 , wherein a priority of one of the tasks is changed responsive to the capacity of the storage system exceeding a threshold.

4 . The storage system of claim 1 , wherein the processor of the primary storage node and the processor of the secondary storage nodes is a same type of processor.

5 . The storage system of claim 1 , wherein to adjust power consumption comprises:

reducing a network load by slowing activities within the storage system.

6 . The storage system of claim 1 , wherein power consumption for cooling one of the plurality of secondary storage nodes is adjusted by shifting processing among the solid state drives.

7 . The storage system of claim 1 , wherein the storage memory is flash memory and wherein adjusting power consumption is achieved by increasing an amount of planes written to in parallel.

8 . A method, comprising:

assigning a first priority to front end tasks to be executed;

assigning a second priority to background tasks to be executed;

monitoring by a processor on a primary storage node of a storage system a processing load of secondary storage nodes of the storage system;

monitoring by the processor on the primary storage node a storage capacity of the storage system;

continuously adjusting a power consumption of a processor of a secondary storage node based on the monitoring and availability of compute resources on the secondary storage node for executing the tasks assigned the first priority.

9 . The method of claim 8 , wherein the front end tasks include tasks including interaction with an external device and background tasks include garbage collection and compression.

10 . The method of claim 8 , wherein exceeding a threshold for capacity triggers changing one background task from a second priority to a first priority.

11 . The method of claim 8 , wherein the processor of primary storage node is a same type of processor as the processor of the secondary storage node.

12 . The method of claim 8 , wherein adjusting the power consumption of the processor comprises idling a portion of cores of the processor.

13 . The method of claim 8 , wherein a remaining portion of cores is sufficient to execute the tasks having the first priority.

14 . The method of claim 8 , further comprising:

shifting processing loads among the secondary storage nodes responsive to a temperature alert in one of the secondary storage nodes.

15 . The method of claim 8 , wherein one of the secondary storage node comprises flash memory and wherein adjusting power consumption is achieved by increasing an amount of planes written to in parallel.

16 . A non-transitory computer readable storage medium storing instructions, which when executed, cause a processing device of a storage controller to:

assign a first priority to front end tasks to be executed;

assign a second priority to background tasks to be executed;

monitor by a processor on a primary storage node of a storage system a processing load of secondary storage nodes of the storage system;

monitor by the primary storage node a storage capacity of the storage system;

continuously adjust a power consumption of a processor of a secondary storage node based on the monitoring and availability of compute resources on the secondary storage node for executing the tasks assigned the first priority.

17 . The computer readable medium of claim 16 , wherein the front end tasks include tasks including interaction with an external device and background tasks include garbage collection and compression.

18 . The computer readable medium of claim 16 , wherein exceeding a threshold for capacity triggers changing one background task from a second priority to a first priority.

19 . The computer readable medium of claim 16 , wherein the processor of the primary storage node is a same type of processor as the processor of the secondary storage node.

20 . The computer readable medium of claim 16 , wherein adjusting the power consumption of the processor comprises idling a portion of cores of the processor.
