Abstract
Power conservation logic for a storage node operates in parallel with an emergency shutdown process in which an emergency power source is engaged and data and metadata are destaged from volatile memory to non-volatile managed drives. The power conservation logic serially implements power conservation actions until enough reserve power is available to complete the emergency shutdown process. The power conservation logic may learn how much power savings are realized from each conservation action and adjust the order in which the conservation actions are serially implemented, e.g. in order from greatest to least power consumption reduction.
