Detailed description of the invention
Embodiments provide data manipulation method and the device of dormancy disk.The core of the present invention is in that: according to the access of disk frequent degree disk is divided into focus disk and non-focus disk two types (access frequent degree high be focus disk, access frequent degree low be non-focus disk), and the type of regular update disk.Further, when the targeted data of data operation request are in non-focus disk, just by the Data Migration in non-focus disk to focus disk.In this way, it is possible to improve hit rate in focus disk, i.e. improve the targeted data of data operation request and be positioned at the probability of focus disk.
So, within the disc dormancy period, once main frame frequently has data operation request, as a rule, the targeted data of these data operation request are all derived from focus disk, and, it is only necessary to frequently wake focus disk up, such that it is able to ensure the resting state (without waking all of disk continually up) of non-focus disk, finally achieve energy-conservation effect.
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
Embodiment one
Referring to Fig. 2, it is the flow chart of an embodiment of data manipulation method of a kind of dormancy disk of the present invention, and the method comprises the following steps:
Step 201: within the disc dormancy period, the frequent degree of access of periodic statistical disk, disk is divided into focus disk and non-focus disk by the frequent degree of access of the described disk according to periodic statistical, wherein, accessing the high disk of frequent degree is focus disk, and accessing the low disk of frequent degree is non-focus disk；
Consult shown in Fig. 3, according to the frequent degree of the access of disk, disk is divided into focus disk and non-focus disk.
It should be noted that in technical solution of the present invention, it is possible to there is a lot of methods to describe the frequent degree of access of a disk.
Preferably, the frequent degree of the access of disk includes: total access times of disk and/or the longest access interval of disk.And total access times are more big and/or the longest access interval more hour, access frequent degree more high, when the more little and/or the longest access interval of total access times is more big, access frequent degree more low.
Such as, a frequency threshold value can be preset and/or preset an interval threshold, when total access times of disk more than or equal to this frequency threshold value and/or the longest access interval less than or equal to this interval threshold time, the frequent degree of access of disk is high, when total access times of disk less than this frequency threshold value and/or the longest access interval more than or equal to this interval threshold time, the frequent degree of access of disk is low.Certainly, total access times of all disks or the longest access interval can also be ranked up, then a precedence threshold value is set, come the frequent degree of the disk access before this precedence threshold value high, focus disk can be divided into, come the frequent degree ground of this precedence threshold value disk access below, non-focus disk can be divided into.
Further, the total access times according to disk can also calculate disk average access frequency in a certain preset time period, i.e. the time of the access times in average access frequency=a certain preset time period/a certain preset time period.Average access frequency may also be used for describing the frequent degree of access of disk, i.e. when average access frequency is more than or equal to predeterminated frequency threshold value, accesses frequent degree high, when average access frequency is less than predeterminated frequency threshold value, accesses frequent degree low.Or, by the average access frequency of each disk is ranked up distinguishing the frequent degree of access of disk.
Further, disk average access interval in a certain preset time period can also be calculated according to all access intervals of disk, i.e. average access interval=all access interval/interval numbers.Equally, average access interval may also be used for describing the frequent degree of access of disk, i.e. when average access interval is less than or equal to predetermined interval threshold value, accesses frequent degree high, when average access interval is more than predetermined interval threshold value, accesses frequent degree low.Or, by the average access interval of each disk is ranked up distinguishing the frequent degree of access of disk.
In addition to this it is possible to obtain other by other mathematics differentiation mode can describe the parameter accessing frequent degree, will not enumerate here.It should be noted that the frequency threshold value preset, default interval threshold and default frequency threshold arbitrarily can be set according to actual needs by user, technical solution of the present invention is not specifically limited.
Also, it should be noted preset time period arbitrarily can also be set according to actual needs by user, it can be the interval between current once statistics and last statistics, consults shown in Fig. 4.Certainly, if the interval between current once statistics and last statistics is long, it is also possible to be a period of time therein.Furthermore it is also possible to be in this dormancy time section, start to current once interval statistics from first time statistics.
In the inventive solutions, must flow through in the following manner to improve the hit rate of focus disk: the frequent degree of access of periodic statistical disk, disk is divided into focus disk and non-focus disk by the frequent degree of the access of disk according to recent statistics, and by the Data Migration in non-focus disk to focus disk.Therefore, it is more frequent that this part performs, and the hit rate of focus disk is more high.
Preferably, after receiving the data operation request that main frame sends, or, after often carrying out a data manipulation, just add up the frequent degree of access of a disk, and according to the frequent degree of access of the disk of recent statistics, disk is divided into focus disk and non-focus disk, and by the Data Migration in non-focus disk to focus disk.
Step 202: the data operation request sent within the disc dormancy period in response to main frame, it is determined that described data operation request targeted by operation data at described focus disk still in described non-focus disk；
Step 203: if it is determined that described by operation data in described focus disk, only wake up described by operation data place focus disk, in the focus disk waken up described by operation data carry out corresponding data manipulation.
Step 204: operated data in described non-focus disk if it is determined that described, only wake the described non-focus disk by operation data place up, described in the non-focus disk waken up is carried out corresponding data manipulation by operation data, and by the Data Migration in the non-focus disk that wakes up to described focus disk.
In the present embodiment, focus disk and non-focus disk within the disc dormancy period all in resting state.Owing to focus disk can be accessed continually, therefore, except this implementation, it is also possible to be that focus disk is in wake-up states within the disc dormancy period, and only allow non-focus disk within the disc dormancy period in a dormant state.In this case, step 203 can be omitted wake this step of focus disk up.
It is last it should be noted that in technical solution of the present invention, data operation request includes data read request and data write request.
Such as, main frame sends data read request within the disc dormancy period, if this data read request targeted be read data in focus disk, only wake the focus disk being read data place up, then read and the focus disk waken up is read data.If the targeted reading data of this data read request are in non-focus disk, only wake the non-focus disk being read data place up, then read and the non-focus disk waken up is read data.
As can be seen from the above-described embodiment, compared with prior art, it is an advantage of the current invention that:
Within the disc dormancy period, once main frame frequently has data operation request, as a rule, the targeted data of these data operation request are all derived from focus disk, and, have only to frequently wake focus disk up, such that it is able to ensure the resting state (without waking all of disk continually up) of non-focus disk, finally achieve energy-conservation effect.
Embodiment two
In above example one, it is contemplated that the feature that focus disk is accessed frequently, preferably, unification arranges focus disk and is in wake-up states within the disc dormancy period all the time one.
And in the present embodiment, consider if focus disk is in wake-up states all the time, energy-conservation effect cannot be embodied better, after the frequent degree of the access having added up disk each time, the frequent degree that accesses according to focus disk determines that focus disk now is once in wake-up states in time period before statistics in distance and is in resting state, so by segment processing mode realize on focus disk energy-conservation.
Referring to Fig. 5, it is the flow chart of another embodiment of data manipulation method of a kind of dormancy disk of the present invention, and the method comprises the following steps:
Step 501: within the disc dormancy period, the frequent degree of access of periodic statistical disk, disk is divided into focus disk and non-focus disk by the frequent degree of access of the described disk according to periodic statistical, wherein, accessing the high disk of frequent degree is focus disk, and accessing the low disk of frequent degree is non-focus disk；
Step 502: described focus disk is set according to the frequent degree of access of described focus disk and is in wake-up states or in a dormant state in described dormancy time section；
Wherein, access frequent degree more than or equal to when presetting frequent degree threshold value, described focus disk is set and is in wake-up states, access frequent degree less than when presetting frequent degree threshold value, described focus disk is set in a dormant state.
Arbitrarily can being set according to actual needs by user it should be noted that preset frequent degree threshold value, technical solution of the present invention is not specifically limited.
Such as, as shown in Figure 4, after second time statistics, if according to the frequent degree of access of second time statistical result determined focus disk is more than default frequent degree threshold value, then arranges in focus disk interval between second time statistics and third time statistics and be in wake-up states.
Step 503: the data operation request sent within the disc dormancy period in response to main frame, it is determined that described data operation request targeted by operation data at described focus disk still in described non-focus disk；
Step 504: operated data in described focus disk if it is determined that described, judge that the described focus disk by operation data place is currently at wake-up states or resting state, if in a dormant state, enter step 505, if being in wake-up states, enter step 506；
Step 505: wake the described focus disk by operation data place up, and the data that operated in the focus disk waken up are carried out corresponding data manipulation, process ends；
Step 506: directly the data that operated in the focus disk waken up are carried out corresponding data manipulation, process ends, process ends；
Step 507: operated data in described non-focus disk if it is determined that described, only wake the described non-focus disk by operation data place up, the data that operated in the non-focus disk waken up are carried out corresponding data manipulation, and by the Data Migration in the non-focus disk that wakes up to described focus disk, process ends.
As can be seen from the above-described embodiment, compared with prior art, it is an advantage of the current invention that:
Within the disc dormancy period, once main frame frequently has data operation request, as a rule, the targeted data of these data operation request are all derived from focus disk, and, have only to frequently wake focus disk up, such that it is able to ensure the resting state (without waking all of disk continually up) of non-focus disk, finally achieve energy-conservation effect.
Implement three
Below for a concrete application scenarios, explain the data manipulation method to dormancy disk.Wherein, it is arranged in the disk of storage server in sleep procedure, whenever receiving the data read request of application server, implements data manipulation as follows.
Referring to Fig. 6, it is the flow chart of an embodiment of method for reading data of a kind of dormancy disk of the present invention, and the method comprises the following steps:
Step 601: inquiry data read request for the mapped disk of data；
For convenient description below, by data read request for the mapped disk of data referred to as target disk.
Step 602: update the history access record of target disk according to this data read request；
Wherein, in the history access record of disk, at least record has total access times of this disk.
Step 603: inquire about the attribute of target disk, and the attribute according to target disk wakes up just at the disk of dormancy, and reading data return to application server from target disk；
According to attribute, disk is divided into focus disk and non-focus disk, and wherein, within the disc dormancy period, focus disk is in wake-up states all the time, but not focus disk when no data operates in a dormant state, and be waken up when there being data manipulation.
Such as, finding after queried the attribute of target disk, having 4 target disks in 5 target disks is focus disk, and other 1 target disk is non-focus disk.Owing to focus disk is in wake-up states, but not focus disk is in a dormant state, therefore, only need to wake 1 non-Thermomagnetic disc in a dormant state up.
Step 604: read total access times of target disk the attribute of the total each disk of access times ranking replacement according to each disk from the history access record of each disk, and by the Data Migration in non-focus disk to focus disk；
Step 605: wake the focus disk after renewal up, the non-focus disk after dormancy renewal.
It should be noted that said method is applied equally to data write operation.
As can be seen from the above-described embodiment, compared with prior art, it is an advantage of the current invention that:
Within the disc dormancy period, once main frame frequently has data operation request, as a rule, the targeted data of these data operation request are all derived from focus disk, and, have only to frequently wake focus disk up, such that it is able to ensure the resting state (without waking all of disk continually up) of non-focus disk, finally achieve energy-conservation effect.
