Embodiment
The present invention proposes a kind of disk array implementation method and device, disk array function can realized, under the prerequisite that guarantees data security, reduce the waste of the energy, it is conceived substantially: to master disk I/O error rate, parameters such as Bad Track detect, and then its health status are assessed, when assessment result is a master disk when being in health status, control is in park mode from disk; When assessment result is a master disk when being in sub-health state, control is in operational mode from disk, thereby reaches the purpose that reduces the computing machine overall power.
Describe embodiment of the present invention in detail below in conjunction with accompanying drawing.
Referring to Fig. 2, the figure shows a kind of disk array implement device of the embodiment of the invention, comprise the state detection unit, assessment control module, the Energy Saving Control unit that link to each other successively, and difference variable lock unit, wherein:
Described state detection unit detects in order to the state parameter to master disk, comprises parameters such as magnetic disc i/o error rate, Bad Track are detected, and the parameter detecting result is sent to described assessment control module.Described state detection unit can be regularly detects the state parameter of master disk, and the user also can select the Disk State parameter is continued to detect.
Described assessment control module in order to after receiving the parameter detecting result that described state detection unit sends, carries out state estimation according to default Rules of Assessment, and the state estimation result is sent to described Energy Saving Control unit.Described Rules of Assessment can be provided with as required, for example, can be the parameters that needs to detect threshold value is set, and the value of detected parameters and corresponding threshold value compared, respectively whether parameters is met the requirements judge, and for example satisfied parameter that reaches certain data volume of setting meets the requirements as assessment result for being in health status, perhaps be provided with and satisfy several designated parameters and meet the requirements as assessment result for being in health status, or the like the evaluation condition of this class.
Described Energy Saving Control unit in order to receive and to judge the state estimation result that described assessment control module sends, if described assessment result indication master disk is in health status, is then controlled from disk and is in park mode; If described assessment result indication master disk state is in sub-health state, then controls and be in operational mode from disk.
Further, described Energy Saving Control unit controls is in operational mode from disk and comprises: control is restarted from disk, and control principal and subordinate disk carries out synchronously.
Further, described Energy Saving Control unit, after control principal and subordinate disk is finished synchronously, also make described from disk as new master disk its place disk array, make other disks in the described disk array as new from disk.
Further, described Energy Saving Control unit after control principal and subordinate disk is finished synchronously, also sends the information that substitutes former master disk to the user.
Further, described Energy Saving Control unit only starts the master disk in the disk array when starting disk array.
Further, described Energy Saving Control unit when disk enters operational mode, also sends synchronous control command to described difference variable lock unit in control.
Described difference variable lock unit in order to after receiving the synchronous control command that sends described Energy Saving Control unit, carries out the synchronous of difference variable to principal and subordinate's disk.
Referring to Fig. 3, the figure shows a kind of disk array implementation method of the embodiment of the invention, comprise the steps:
Step S301: the state parameter that detects master disk;
The parameter detecting of master disk is comprised detection to parameters such as magnetic disc i/o error rate, Bad Tracks.
Can regularly detect the Disk State parameter, the user also selects the Disk State parameter is continued to detect.
Step S302:, master disk is carried out state estimation according to state parameter testing result to master disk;
When master disk is carried out state estimation, be to carry out according to a default Rules of Assessment.Described Rules of Assessment can be provided with as required, in order to detected parameters carried out analysis-by-synthesis and to obtain the state estimation result of master disk.For example, can be the parameters that needs to detect threshold value is set, and the value of detected parameters and corresponding threshold value compared, respectively whether parameters is met the requirements judge, and for example satisfied parameter that reaches certain data volume of setting meets the requirements as assessment result for being in health status, perhaps be provided with and satisfy several designated parameters and meet the requirements as assessment result for being in health status, or the like the evaluation condition of this class.
Step S303: judgement is in health status to the state estimation result of master disk if assessment result is a master disk, then controls from disk to be in park mode; Be in sub-health state if assessment result is a master disk, then control and be in operational mode from disk.
Wherein, control enters operational mode from disk and is meant that control restarts from disk, triggers synchronous to from disk and master disk.
Preferably, in control when disk enters operational mode, also trigger to master disk and from disk carry out the difference variable synchronously, synchronous fully to realize master and slave disk.
Preferably, after control principal and subordinate disk is finished synchronously, also make described from disk as new master disk its place disk array, make other disks in the described disk array as new from disk, thereby in time with former from disk replace be in sub-health status former master disk as new master disk, to guarantee safety of data.
Preferably, after control principal and subordinate disk is finished synchronously, can also send the information that substitutes former master disk to the user, make the user can in time know the health status of disk array Central Plains master disk, and in time replace the former master disk that is in sub-health state, the user newly be substituted in the disk array disk will as in the disk array newly from disk.
Preferably, when starting computer system, can only start the master disk in the disk array, only when this master disk is in inferior health, just start, thereby can further reduce unnecessary power consumption from disk.
The present invention by dexterously with master disk state estimation result as the judgment standard that whether moves from disk, when master disk is in health status, can controls and be in park mode, thereby reduce the unnecessary power consumption of computing machine from disk.
Please in conjunction with method shown in Figure 3, continuation referring to Fig. 4 (a) to Fig. 4 (d), wherein Fig. 4 (a), Fig. 4 (b), Fig. 4 (c), Fig. 4 (d) are according to the signal of time order and function order to principal and subordinate's disk storage state: when computer starting, only start master disk (shown in Fig. 4 (a)); Detect and assessment master disk situation, find that master disk is in health status, control is in park mode (shown in Fig. 4 (b)) from disk; Detect and assessment master disk situation, find that master disk is in sub-health status, control is in operational mode (shown in Fig. 4 (c)) from disk, comprises startup from disk, and control principal and subordinate disk is synchronous; Principal and subordinate's disk is finished (shown in Fig. 4 (d)) synchronously.Therefrom adopt the present invention program to be under the situation of health status at master disk as can be seen, order is in park mode from disk, thereby reduces the unnecessary power consumption of computing machine.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.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.
