Power supply 35 improves the voltage that exports fan 36 to according to the work steering order, and is in running order with control fan 36; Instruction reduces the voltage that exports fan 36 to power supply 35 according to Energy Saving Control, is in power save mode with control fan 36.The duty of fan 36 is full-speed operation, and the power save mode of fan 36 is a low-speed running.
Wherein, energy-saving distribution module 31 comprises time scheduling unit 311, instruction scheduling unit 312 and Energy Saving Control unit 313.Time scheduling unit 311 links to each other with Energy Saving Control unit 313; Instruction scheduling unit 312 links to each other with Energy Saving Control unit 313; Energy Saving Control unit 313 links to each other respectively with time scheduling unit 311, instruction scheduling unit 312, CPU32, storage control card 33 and power supply 35.
Time scheduling unit 311 generates second according to energy-saving run cycle of setting in advance and starts duty instruction or second and start the power save mode instruction, and starts duty instruction or second with second and start the power save mode instruction and export Energy Saving Control unit 313 to.Particularly, time scheduling unit 311 produces and exports the second startup duty and instruct to Energy Saving Control unit 313 when determining arrival working time hatch section; Time scheduling unit 311 produces and exports second and start power save mode and instruct to Energy Saving Control unit 313 when determine arriving energy-conservation time period.In the embodiments of the invention, when time scheduling unit 311 produces and exports the second startup duty instruction, can instruct to Energy Saving Control unit 313 according to setting in advance output services, just time scheduling unit 311 can instruct to Energy Saving Control unit 313 according to setting in advance output backup instruction or recovery.
Instruction scheduling unit 312 is after the work order that receives outside input, and output starts first duty and instructs to Energy Saving Control unit 313; Instruction scheduling unit 312 receive corresponding with the work order of outside input finish instruction after, output first starts power save mode and instructs to Energy Saving Control unit 313.When instruction scheduling unit 312 starts the duty instruction in output first, export the content of the work order of the outside input that receives to Energy Saving Control unit 313.The content of the work order of outside input is a back up or restore.
Energy Saving Control unit 313 is after receiving the first startup duty instruction, and the output services steering order is to CPU32, storage control card 33 and power supply 35; Energy Saving Control unit 313 is after receiving the first startup power save mode instruction, and the output Energy Saving Control instructs to CPU32, storage control card 33 and power supply 35.Energy Saving Control unit 313 exports the content of the work order that receives to CPU32 in the output services steering order.
Energy Saving Control unit 313 receive first start the duty instruction before, receive second and start duty and instruct then the output services steering order to CPU32, storage control card 33 and power supply 35; Energy Saving Control unit 313 is after receiving the second startup power save mode instruction, if judge that himself not receiving first starts the duty instruction, then exporting Energy Saving Control instructs to CPU32, storage control card 33 and power supply 35, if judge that himself having received first starts the duty instruction and do not receive the first startup power save mode instruction, then the output services steering order is just exported Energy Saving Control and is instructed to CPU32, storage control card 33 and power supply 35 after receiving the first startup power save mode instruction.
Energy-saving distribution module 31 is when the output services steering order, export the content of the interior work order that perhaps himself produces of the operate outside that receives instruction to CPU32, the instruction that is used for back up or restore of the outside input that is about to receive or the back up or restore instruction that himself produces export CPU32 to, so that CPU32 control store control card 33 is realized data backup or recovery.CPU32 control store control card 33 realizes that the content of data backup or recovery is a prior art, does not repeat them here.
In the present embodiment, Energy Saving Control unit 313 is judging that self having received first starts the duty instruction, but when not receiving the first startup power save mode instruction, ignore the second startup power save mode instruction that receives, this ignores second operation that starts the power save mode instruction that receives is in order to guarantee that memory device can keep peak performance all the time when need of work is arranged, and can be because of making memory device performance under the situation that has work carrying out descend according to the second Energy Saving Control instruction that starts power save mode instruction generation, in fact, if for the insensitive application of performance, this judgement also can not done in Energy Saving Control unit 313, carries out subsequent operation as long as the startup duty that basis receives instruction or startup power save mode instruct.

Step 510: judging whether to receive the instruction of finishing of outside input, is execution in step 511 then, otherwise execution in step 510;
Memory device judges whether to receive the instruction of finishing of outside input, is execution in step 511 then; Otherwise execution in step 510, memory device are waited for outside input corresponding with work order finishes instruction.
Memory device is when waiting for that finishing of outside input instructed, CPU32, hard disk 34 and fan 36 in the memory device are in running order, at this moment, the exportable work steering order of memory device is to CPU32, storage control card 33 and power supply 35, perhaps memory device is not exported steering order to CPU32, storage control card 33 and power supply 35, and CPU32, hard disk 34 and fan 35 still just run on duty.
Step 511: the instruction of output Energy Saving Control, execution in step 502 afterwards;
Memory device can will export CUP32, storage control card 33 and power supply 35 to according to the second Energy Saving Control instruction that starts power save mode instruction generation, also can be according to the instruction of finishing of the outside input that receives, generate first and start the power save mode instruction, to export CUP32, storage control card 33 and power supply 35 to according to the first Energy Saving Control instruction that starts power save mode instruction generation, execution in step 502 afterwards.
In the storage means of present embodiment, memory device according to said method circulation execution in step 502 to step 511.
In the above-mentioned preferred embodiment of the present invention, CPU can dynamically change the frequency of operation of moving for supporting the central processing unit of converter technique in operational process, and how CPU is prior art according to the content of steering order change frequency of operation, does not repeat them here; Whether the storage control card can by loading on the rotating speed that hard disk is controlled hard disk with voltage, and the content how the storage control card controls the rotation speed of hard disk is a prior art, does not repeat them here; The content that the voltage that power supply exports fan to by change changes rotation speed of the fan is a prior art, does not repeat them here.
In sum, more than be preferred embodiment of the present invention only, be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
