Apparatus, system, and method for power reduction management in a storage device
First Claim
1. A method for power loss management in a storage device, the apparatus comprising:
- initiating a power loss mode in a nonvolatile data storage device in response to a primary power source failing to supply electric power above a predefined threshold to the nonvolatile data storage device;
accepting electric power for the nonvolatile data storage device from a secondary power source for at least a power hold-up time during the power loss mode; and
adjusting execution of in-process operations on the nonvolatile data storage device during the power loss mode such that essential in-process operations execute within the power hold-up time.

Abstract
An apparatus, system, and method are disclosed for power loss management in a nonvolatile data storage device. A monitor module initiates a power loss mode in the nonvolatile data storage device in response to a primary power source failing to supply electric power above a predefined threshold to the nonvolatile data storage device. A secondary power source supplies electric power to the nonvolatile data storage device for at least a power hold-up time during the power loss mode. A power loss module adjusts execution of in-process operations on the nonvolatile data storage device during the power loss mode so that essential in-process operations execute within the power hold-up time.
