System and method for power management of storage resources
View Patent ↗A system and method for power management of storage resources are disclosed. A method may include detecting an occurrence of an event associated with a storage resource disposed in an array of storage resources. The method may further include transitioning the storage resource into a specified power state in response to the detection of the occurrence of the event. A system may include a storage resource and a power management module communicatively coupled to the storage resource. The storage resource may be disposed in an array of storage resources. The power management module may be operable to detect an occurrence of an event associated with the storage resource, and may be operable to transition the storage resource into a specified power state in response to the detection of the occurrence of the event.
1. A method for power management of storage resources comprising:
detecting an occurrence of an event associated with a spare storage resource disposed in an array of storage resources, the spare storage resource being at least partially powered on and in a spun down state;
based on the occurrence of the event, spinning up the spare storage resource from the spun down state and evaluating a condition of the spare storage resource to determine whether the spare storage resource is functioning properly;
based on the spare storage resource functioning properly, transitioning the spare storage resource into an active storage resource; and
based on the spare storage resource not functioning properly, spinning down the spare storage resource.
2. The method of claim 1 , wherein the array of storage resources comprises a redundant array of independent disks (RAID).
3. The method of claim 1 , wherein the event comprises at least one of: rebuilding of a virtual resource using the spare storage resource, issuance of a configuration command associated with the spare storage resource, removal of a storage resource from the array of storage resources, detecting a failure of a storage resource, and issuance of a command to check the condition of the spare storage resource.
4. The method of claim 1 , wherein the event is issued by a power management module communicatively coupled to the array of storage resources.
5. The method of claim 4 , wherein the power management module periodically issues the event, the event comprising issuance of a command to check the condition of the spare storage resource.
6. The method of claim 1 , further comprising issuing, based on a determination that the spare storage resource is not functioning properly, a configuration command to a second spare storage resource, the event comprising detecting a failure of a storage resource.
7. The method of claim 1 , further comprising issuing, based on a determination that the spare storage resource is not functioning properly, a configuration command to a second spare storage resource, the event comprising a removal of a storage resource from the array of storage resources.
8. An information handling system comprising:
a processor;
a memory communicatively coupled to the processor; and
a power management module communicatively coupled to the processor and a spare storage resource disposed in an array of storage resources, the power management module operable to:
detect an occurrence of an event associated with the spare storage resource disposed in the array of storage resources, the spare storage resource being at least partially powered on and in a spun down state;
based on the occurrence of the event, spin up the spare storage resource from the spun down state and evaluate a condition of the spare storage resource to determine whether the spare storage resource is functioning properly;
based on the spare storage resource functioning properly, transition the spare storage resource into an active storage resource; and
based on the spare storage resource not functioning properly, spin down the spare storage resource.
9. The information handling system of claim 8 , wherein the array of storage resources comprises a redundant array of independent disks (RAID).
10. The information handling system of claim 8 , wherein the event comprises at least one of: rebuilding of a virtual resource using the spare storage resource, issuance of a configuration command associated with the spare storage resource, removal of a storage resource from the array of storage resources, detecting a failure of a storage resource, and issuance of a command to check the condition of the spare storage resource.
11. The information handling system of claim 8 , wherein the power management module is further operable to periodically issue the event, the event comprising issuance of a command to check the condition of the spare storage resource.
12. The information handling system of claim 8 , wherein the power management module is further operable to issue, based on a determination that the spare storage resource is not functioning properly, a configuration command to a second spare storage resource, the event comprising detecting a failure of a storage resource.
13. The information handling system of claim 8 , wherein the power management module is further operable to issue, based on a determination that the spare storage resource is not functioning properly, a configuration command to a second spare storage resource, the event comprising a removal of a storage resource from the array of storage resources.
14. A power management module comprising instructions stored therein, the instructions readable by a processor and, when read and executed, configured to cause the processor to:
detect an occurrence of an event associated with a spare storage resource disposed in an array of storage resources, the spare storage resource being at least partially powered on and in a spun down state;
based on the occurrence of the event, spin up the spare storage resource from the spun down state and evaluate a condition of the spare storage resource to determine whether the spare storage resource is functioning properly;
based on the spare storage resource functioning properly, transition the spare storage resource into an active storage resource; and
based on the spare storage resource not functioning properly, spin down the spare storage resource.
15. The power management module of claim 14 , wherein the array of storage resources comprises a redundant array of independent disks (RAID).
16. The power management module of claim 14 , wherein the event comprises at least one of: rebuilding of a virtual resource using the spare storage resource, issuance of a configuration command associated with the spare storage resource, removal of a storage resource from the array of storage resources, detecting a failure of a storage resource, and issuance of a command to check the condition of the spare storage resource.
17. The power management module of claim 14 , wherein the instructions are further configured to cause the processor to periodically issue the event, the event comprising issuance of a command to check the condition of the spare storage resource.
18. The power management module of claim 14 , wherein the instructions are further configured to cause the processor to issue, based on a determination that the spare storage resource is not functioning properly, a configuration command to a second spare storage resource, the event comprising detecting a failure of a storage resource.
19. The power management module of claim 14 , wherein the instructions are further configured to cause the processor to issue, based on a determination that the spare storage resource is not functioning properly, a configuration command to a second spare storage resource, the event comprising a removal of a storage resource from the array of storage resources.
