Below in conjunction with drawings and Examples, technical scheme of the present invention is described.
In realizing process of the present invention, the inventor is through research and test of many times are summed up discovery repeatedly, the principle that reads and writes data based on the magnetic head high-speed seek, magnetic head in the high-speed seek process if meet with external shock, then thereby magnetic head hits card easily and produces bad track even damage disk, and when shockproofness when very low or disk is in off working state, disk is then not fragile, thus the disk vibrations when strong disk to be in the high speed read-write state be the major reason that causes disk failures.Based on above analysis, the inventor has proposed to control the professional method of promptly controlling the disk read-write state to protect disk from root according to the shock conditions of disk, is elaborated below by specific embodiment.
With reference to Fig. 1, be the method flow diagram of a kind of disk protect of the embodiment of the invention.This method can comprise:
Step 101 receives the vibration information of disk at the fixed time.
In disk inside or other position shock sensor can be set as required, come in real time or the vibrating state at each position of periodic monitor recording disc.This vibrating state can directly be received by the system that is used to protect the server of this disk or be arranged on the server as the disk vibration information; Shock sensor also can carry out simple process to this vibrating state, as be processed into the intensity level of vibrations or the vibration informations such as rank of vibrations, both can directly be passed to server or system, also can work as the disk vibrations that obtain when reaching certain intensity, report to server or system again.
Wherein, the schedule time can be only to set one or several fixing moment, is undertaken once or the reception of vibration information several times by server or system; Also can be set at the time interval, in this time interval of every process, as 1min, shock sensor is just uploaded and is once shaken message, and server or system just receive primary information.The setting of this schedule time can be provided with according to customer demand and concrete application scenarios.
The system that is used to protect the server of this disk in this step or is arranged on the server can determine shockproofness according to the vibration information that shock sensor reports; compare with the default one or more threshold values of internal system then; certainly, if comprised the intensity level of vibrations in the vibration information that shock sensor reports then can directly compare.
Wherein, predetermined threshold information is to monitor in real time through early stage disk being shaken, each position vibrating state of recording disc, by long-term lot of data statistics, the reasonable threshold value of setting out, this threshold value can comprise threshold value of warning and damaging thresholding, also can also comprise other threshold value, as secure threshold etc.
Can determine the corresponding vibrations rank of the residing threshold range of this shockproofness according to the disk shockproofness and the comparison of each threshold value, can safeguard the relation table of each rank threshold range and each rank relative strategy in server or the system, so that carry out follow-up business control according to corresponding strategy.
If the vibrations rank of disk is higher, disk is exerted an influence, then operations such as follow-up minimizing distribution of services or transfer disk business can be carried out,, then the distribution of regular traffic can be carried out this disk if the rank of disk vibrations still belongs to level of security to corresponding disk.Certainly the corresponding relation between vibrations rank and the professional control strategy can be adjusted and revise as required.
In the embodiment of the invention; based on disk vibrations when strong disk to be in the high speed read-write state be the analysis that causes the major reason of disk failures; by obtaining the vibrations rank of disk; control the service condition of disk then according to the vibrations rank of disk; also promptly control the read-write state of disk according to the vibrations rank of disk; thereby strengthened anti-vibration protected to disk, increased disk serviceable life greatly, reduced the disk cost.。In addition, also reduced because of changing maintainer's human cost that disk produces, reduced because of the disk failures data reconstruction to the extra load that system brings, guarantee system's reliability service.
