Abstract
A system, method, and module for reducing power states for storage devices and associated logical volumes are disclosed. In one form, a method of altering an operating state of a storage device can include detecting a request to access a first logical volume over an interval. The method can also include determining an association of a storage device to the first logical volume. The method can further include determining if the storage device is operably associated with a second logical volume, and altering an operating state of the storage device in response to detecting the request and determining the association with the second logical volume.
Claims20
A method of altering an operating state of a storage device comprising:
- detecting a request to access a first logical volume over an interval;
- determining an association of a storage device to the first logical volume;
- determining if the storage device is operably associated with a second logical volume;
- and
- altering an operating state of the storage device in response to detecting the request and determining the association with the second logical volume.
A processing module comprising:
- an interface operable to detect a request to access a logical volume operably associated with a plurality of storage devices, the plurality of storage devices operably associated with plural logical volumes;
- and
- a controller operable to initiate altering an operating status of the logical volume and an associated first storage device in response to detecting the request over an interval.
An information handling system comprising:
- a controller operable to alter an operating state of a plurality of storage devices;
- and
- a logical volume manager operably coupled to the controller, the logical volume manager operable to:
- detect an I/O request to access information stored in association with a first logical volume operably associated with the plurality of storage devices over an access period;
- determine if a first storage device of the plurality of storage devices is operably associated with a second logical volume and the first logical volume;
- determine an operating state of a second storage device of the plurality of storage devices operably associated with the second logical volume and the first logical volume;
- and
- initiate reducing the operating state of the plurality of storage devices when the I/O request is not detected within the access period.
