Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
Core concept of the present invention is: in order to realize that hard disk is further energy-conservation in the memory device, need enter the IDLE state when hard disk does not carry out data transmission, and idle the time, then close the hard disk power supply long-time.
As shown in Figure 1, hard disk controller is responsible for the data transmission of each hard disk in the memory device and the state of monitoring each hard disk on one side, by I/O (I/O) interface with miscellaneous equipment communicate by letter on one side.When the time that it detects a hard disk wherein and do not have effective read-write reaches the time threshold that is provided with in the memory device and this hard disk and is in idle condition, also be used for sending power cutoff instruction, the sign of wherein carrying this hard disk to power-supply controller of electric.The power supply that power-supply controller of electric is corresponding with hard disk controller and each hard disk respectively links to each other, and it is used for after the above-mentioned power cutoff instruction, turn-offing the power supply of corresponding hard disk correspondence on receiving.The user can also utilize some man-machine interface A PI (application programming interfaces) functions, sends instructions to power-supply controller of electric; Power-supply controller of electric then can be closed/open operation the hard disk power supply by analyzing.
When the time that hard disk controller detects a hard disk in the memory device and do not have effective read-write reached above-mentioned time threshold and this hard disk and is in the read/write state, this hard disk controller also was used for the state of this hard disk is changed to the free time and sends the power cutoff instruction to above-mentioned power-supply controller of electric.Also be used for after the request that receives certain hard disk of desire use memory device, this request being sent to described power-supply controller of electric;
Power-supply controller of electric also is used for judging whether to be necessary power cutoff after receiving the power cutoff instruction, and carries out shutoff accordingly or do not turn-off operation according to judged result; Also be used for receive hard disk controller or user directly by API after the request of the above-mentioned use hard disk of its transmission, judge whether the power supply of this hard disk correspondence is in off state, if then also be used to open the power supply of this hard disk correspondence.
As shown in Figure 2, realize the method for energy saving of hard disks in the memory device, may further comprise the steps: after memory device started, each hard disk carried out the configuration of initialization and monitoring parameter earlier, when treating that each hard disk is in normal operating condition, hard disk controller begins to monitor the running status of each hard disk.When finding the effectively read-write of the long-time nothing of certain hard disk, and the time reaches predefined threshold value and (did not for example move in 30 minutes, concrete threshold value can be by the system default setting, also can be provided with by API by the user) time, detect this hard disk and whether be in the IDLE state, if then directly turn-off the power supply of this hard disk, otherwise, the state of this hard disk is changed to behind the IDLE power remove with this hard disk correspondence again.The hard disk of power cutoff promptly enters off-position, has therefore reached purpose of energy saving.In order to prevent that emergency case from taking place, power-supply controller of electric can also be before turn-offing the hard disk power supply, analyze earlier, see if there is necessary power cutoff (as judge whether to turn-off the power supply of this hard disk according to user intention), in this way, close corresponding hard disk power supply again, otherwise, re-execute the step of monitoring hard disk running status.
As shown in Figure 3, certain hard disk need be used in memory device, and hard disk controller learns that through power-supply controller of electric this hard disk is in off-position, and then power-supply controller of electric is opened this hard disk power supply, and hard disk enters the read/write state.Wherein, the situation that hard disk need be used comprises following two kinds: hard disk controller detects this hard disk and need be used, or the user initiates operational order to this hard disk by API to power-supply controller of electric.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
