Abstract
The invention discloses a mode switching method and device, and belongs to the technical field of data processing. The method comprises the steps that whether a data transmission link is currently in an idle state or not is monitored in a non-saving mode; if the monitored data transmission link is currently in the idle state, a storage device in the non-saving mode is switched to be in a saving mode after the time duration of the data transmission link in the idle state reaches a first preset time duration. According to the mode switching method and device, the current state of the data transmission link is monitored, and if the monitored data transmission link is currently in the idle state, the storage device in the non-saving mode is switched to be in the saving mode after the time duration of the data transmission link in the idle state reaches the first preset time duration. Due to the fact that the mode switching process is executed by the storage device, the control of a storage system is not needed, the modes are switched relatively in time, and the burden of the storage system is low. Thus, mode switching efficiency is high.
Description
Technical field
The present invention relates to technical field of data processing, particularly a kind of mode switching method and device.
Background technology
Along with the continuous surge to storage capacity requirement, the memory devices such as hard disk are more and more extensive by what use.Wherein, memory device generally has the several modes such as mode of operation, idle pulley, standby mode and sleep pattern.Wherein, the power consumption consuming under every kind of pattern is all different, according to the power consumption consuming, the pattern of memory device can be divided into save mode and non-save mode, and save mode comprises sleep pattern and standby mode, and non-save mode comprises mode of operation and idle pulley.Because power consumption of memory device under save mode and non-save mode differs greatly, therefore, pattern how to switch memory device according to business demand is to reduce the key of power consumption.
A kind of mode switching method is provided in correlation technique, and in the method, the switching of the pattern of memory device is controlled by storage system.When the pattern that need to switch memory device being detected, to memory device, send switching command, by memory device, switching command is resolved, and switch corresponding pattern according to the order after resolving.
In realizing process of the present invention, inventor finds that said method at least exists following problem:
Because needs are detected memory device by storage system, when detecting, need to carry out after pattern switching, to memory device, send switching command again, by memory device, according to switching command, be switched to corresponding pattern, thereby the process more complicated that pattern is switched, causes the switching of pattern not prompt enough.In addition, because needs are controlled by storage system, cause storage system burden heavier.Therefore, the switching efficiency of pattern is not high.

In addition, if the time span at data transmission link in idle condition reaches a certain moment before the first Preset Time length, to listen to data transmission link current in busy state, now, can be by the numerical value zero clearing of first timer, and carry out according to the method in another branch's step 203 of step 201.
It should be noted that, above-mentioned the handoff procedure of memory device pattern is carried out by the control module in this memory device.In each memory device, be provided with control module, handoff procedure that can control model by control module.
203: continue whether service data transmission bag of monitored data transmission link, if listen to not service data transmission bag of data transmission link, perform step 204, if listen to data transmission link service data transmission bag, perform step 205;
The present embodiment not to monitored data transmission link whether the mode of service data transmission bag do concrete restriction, include but not limited to: by system, by data transmission link, to the control module of memory device, send heartbeat packet; If what within certain period, control module continued to receive is all heartbeat packet, not service data transmission bag of interior data transmission link of this period is described, listen to not service data transmission bag of data transmission link; If at a time listen to data transmission link service data transmission bag, this moment data transmission link service data transmission bag is described, listen to data transmission link service data transmission bag.
Listen to data transmission link whether after service data transmission bag, can determine the follow-up step carried out of needing according to snoop results.If listen to not service data transmission bag of data transmission link, perform step 204, if listen to data transmission link service data transmission bag, perform step 205.
204: data transmission link not the time span of service data transmission bag reach after the second Preset Time length, memory device is switched to save mode by non-save mode;
Listening to data transmission link not after service data transmission bag, can start second timer, by second timer to data transmission link not the time span of service data transmission bag add up, wherein, the time span of second timer is the second Preset Time length.If the accumulated value of second timer has reached the second Preset Time length, data transmission link service data transmission bag not still when second timer is overtime even, specified data transmission link not the time span of service data transmission bag reach the second Preset Time length.Wherein, the second Preset Time length can be set according to the residing scene demand of memory device, and as not being arranged to 10 seconds to 86400 seconds not etc., the present embodiment is not done concrete restriction to the value of the second Preset Time length.
Data transmission link not the time span of service data transmission bag reach after the second Preset Time length, memory device is switched to save mode by non-save mode, now, just completed the switching of memory device pattern in this case.
In addition, if at data transmission link, a certain moment of the time span of service data transmission bag before reaching the second Preset Time length do not listen to data transmission link service data transmission bag, now, can be by the numerical value zero clearing of second timer, and carry out according to the method in another branch's step 205 of step 203.
It should be noted that, as a kind of optional embodiment, first timer and second timer can be same timer, and the present embodiment is not done concrete restriction to this.And no matter whether first timer is identical with second timer, and the first Preset Time length and the second Preset Time length can be the same or different, and the present embodiment is not done concrete restriction equally to this.In addition, above-mentioned the handoff procedure of memory device pattern is carried out by the control module in this memory device.In each memory device, be provided with control module, handoff procedure that can control model by control module.
205: memory device is remained to non-save mode.
Memory device is remained after non-save mode, can continue monitored data transmission link current whether in idle condition, according to the method for above-mentioned steps 201 to 205, continue circulation and carry out.By circulation, carry out said method step, can guarantee need to carry out pattern while switching at memory device, in time the pattern of memory device is switched, thereby make the memory device can be always in best pattern.
The method that the present embodiment provides, by the current state of monitored data transmission link, if it is current in idle condition to listen to data transmission link, at data transmission link, the time span in idle condition reaches after the first Preset Time length, and memory device is switched to save mode by non-save mode.Because the handoff procedure of pattern is carried out by memory device, do not need storage system to control, thereby make the switching of pattern more timely, the burden of storage system is lighter.Therefore, the switching efficiency of pattern is higher.
