Abstract

Various methods and systems are provided for implementing classification-based adjustable seek energy settings in storage device systems. In particular, operations support adjusting seek energy settings for storage device components, for executing requests. In operation, a classification is selected for a request. The classification indicates a first priority level for executing the request. The priority level is associated with a first adjustable seek energy setting of a plurality adjustable seek energy settings for executing requests on the hard disk drive system, where a seek energy setting is an adjustable operational speed or energy setting for the hard disk drive system. Based on the classification indicating the priority level, the classification is transmitted to cause the hard disk drive system to set the adjustable seek energy setting. One or more hardware components of the hard disk drive system operates to execute the first request based on the first adjustable seek energy setting.

First claim

The invention claimed is:

1. A computer-implemented method for implementing classification-based adjustable seek energy settings in storage device systems, the method comprising:
receiving a first request, wherein the first request is an input/output (I/O) request for a hard disk drive system;
selecting a first classification for the first request, wherein the first classification is selected from a plurality of classifications, wherein the first classification indicates a first priority level for executing the first request, the first priority level is associated with a first adjustable seek energy setting of a plurality adjustable seek energy settings for executing requests on the hard disk drive system, wherein a seek energy setting is an adjustable operational speed or energy setting for the hard disk drive system; and
based on the first classification indicating the first priority level associated with the first adjustable seek energy setting, transmitting the first classification to cause the hard disk drive system to set the first adjustable seek energy setting, wherein one or more hardware components of the hard disk drive system operates to execute the first request based on the first adjustable seek energy setting.

2. The method of claim 1 , wherein the first request is an application request for a read operation, a write operation, or a maintenance operation, wherein the application request is associated with an application running on an operating system, wherein the application, the operating system, and the hard disk drive system are configured to process application requests having classifications that indicate the priority levels that correspond to adjustable seek energy settings.

3. The method of claim 1 , wherein selecting the first classification is based on:
accessing a configuration table that includes a plurality of classifications having priority levels and the plurality of adjustable seek energy settings, wherein each of the plurality of classifications is mapped to a corresponding adjustable seek energy setting; and
assigning the first classification to the first request based on the first classification being mapped to the first adjustable seek energy setting within the configuration table.

4. The method of claim 1 , wherein selecting the first classification is further based on a category classification of the request, wherein the category classification is selected from one of the following: a read operation, a write operation, or a maintenance operation, wherein category classifications correspond to predefined classifications for priority levels, wherein the priority levels are selected from one of the following: a high priority, a medium priority, and a low priority.

5. The method of claim 1 , wherein the adjustable operational setting for the hard disk drive system is a setting that causes a read/write head of the hard disk drive system to change a rate for locating tracks corresponding to requests.

6. The method of claim 1 , wherein transmitting the first request comprises an application communicating the first classification to an operating system, wherein the operating system modifies the first classification for the first request to a second classification, and wherein the operating system communicates the first request having the second classification.

7. The method of claim 1 , wherein setting of the first adjustable seek energy setting is further based on a queue depth of a queue associated with a first storage area where the first request is executed, the queue depth is a first quantity of requests that are pending within the queue.

8. One or more hardware computer storage media having computer-executable instructions embodied thereon that, when executed, by one or more processors, cause the one or more processors to perform a method for implementing classification-based adjustable seek energy settings in storage device systems, the method comprising:
receiving a first request, wherein the first request is an input/output (I/O) request received at a storage device system;
determining that the first request is associated with a first classification, wherein the first classification indicates a first priority level for executing the first request, the first priority level corresponds to a first adjustable seek energy setting of a plurality adjustable seek energy settings for executing requests on the storage device system, wherein a seek energy setting is an adjustable operational setting for the storage device system; and
based on the first classification, configure a first adjustable seek energy setting for one or more components of the storage device system, wherein the one or more components operates to execute the first request based on the first adjustable seek energy setting.

9. The one or more hardware computer storage media of claim 8 , wherein the first request is an application request or operating system request, wherein the application request is associated with an application and the operating system request is associated with an operating system, wherein the application, the operating system, and the storage device system are configured to process requests having classifications that indicate the priority levels that correspond to adjustable seek energy settings.

10. The one or more hardware computer storage media of claim 8 , wherein determining that the first request is associated with a first classification is based on a storage device system protocol associated with the storage device system, wherein the storage device system protocol provides the rules or procedures for formatting and processing requests associated with classifications.

11. The one or more hardware computer storage media of claim 10 , wherein the storage device system protocol is associated with a configuration table that includes a plurality of classifications having priority levels and the plurality of adjustable seek energy settings, wherein each of the plurality of classifications is mapped to a corresponding adjustable seek energy setting; and wherein configuring the first adjustable seek energy setting for one or more components of the storage device system is based on the first classification being mapped to the first adjustable seek energy setting within the configuration table.

12. The one or more hardware computer storage media of claim 8 , the method further comprising:
receiving a second request, wherein the second request is an I/O request received at the storage device system;
determining that the second classification is associated with a second classification, the second classification indicates a second priority level for executing the second request, the second priority level corresponds to a second adjustable seek energy setting of a plurality adjustable seek energy settings for executing requests on the storage device system;
accessing a queue depth of a queue associated with a storage area where the second request is to be executed, the queue depth is a first quantity of requests that are pending within the queue; and
based on the queue depth of the queue, selecting a new classification for the second request, wherein the new classification indicates a new priority level for executing the second request, wherein the new priority level is a higher priority level or lower priority level, the new priority level corresponds to a new adjustable seek energy setting of the plurality adjustable seek energy settings for executing requests on the storage device system.

13. The one or more hardware computer storage media of claim 8 , further comprising:
receiving a second request, wherein the second request is an I/O request re
