Embodiment
The embodiment of the present invention provides data manipulation method and the device of dormancy disk.Core of the present invention is: according to the frequent degree of the access of disk by disk be divided into two types of focus disk and non-focus disks (access frequent degree high be focus disk, access frequent degree low be non-focus disk), and the type of regular update disk.And, whenever data operation request institute is for data in non-focus disk time, just by the Data Migration in non-focus disk in focus disk.In this way, can improve hit rate in focus disk, that is, improve data operation request for data, be positioned at the probability of focus disk.
Like this, at disc dormancy in the period, once main frame frequently has data operation request, as a rule, these data operation request for data all derive from focus disk, and, only need to frequently wake focus disk up, thereby the dormant state (and can not wake continually all disks up) that can ensure non-focus disk, has finally realized energy-conservation effect.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
Embodiment mono-
Refer to Fig. 2, the process flow diagram of an embodiment of its data manipulation method that is a kind of dormancy disk of the present invention, the method comprises the following steps:
Step 201: at disc dormancy in the period, regularly add up the frequent degree of access of disk, according to the frequent degree of the access of the described disk of regular statistics, disk is divided into focus disk and non-focus disk, wherein, accessing the disk that frequent degree is high is focus disk, and accessing the disk that frequent degree is low 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, can have a lot of methods to describe the frequent degree of access of a disk.
Preferred mode is that the frequent degree of access of disk comprises: total access times of disk and/or the longest access interval of disk.And total access times more greatly and/or the longest access interval more hour, access frequent degree higher, when total less and/or the longest access of access times interval is larger, access frequent degree lower.
For example, can preset a frequency threshold value and/or preset an interval threshold, when total access times of disk are more than or equal to this frequency threshold value and/or the longest access interval and are less than or equal to this interval threshold, the frequent degree of access of disk is high, when total access times of disk are less than this frequency threshold value and/or the longest access interval and are more than or equal to this interval threshold, the frequent degree of access of disk is low.Certainly, also can sort to total access times of all disks or the longest access interval, then set a precedence threshold value, the frequent degree of disk access coming before this precedence threshold value is high, can be divided into focus disk, come the frequent degree of this precedence threshold value disk access below ground, can be divided into non-focus disk.
Have again, according to total access times of disk, can also calculate the average access frequency of disk in a certain Preset Time section, that is, and the time of the access times/a certain Preset Time section in average access frequency=a certain Preset Time section.Average access frequency also can be used for describing the frequent degree of access of disk,, when average access frequency is more than or equal to predeterminated frequency threshold value, accesses frequent degree high that is, when average access frequency is less than predeterminated frequency threshold value, accesses frequent degree low.Or, by the average access frequency to each disk, sort to distinguish the frequent degree of access of disk.
Also have, according to all access interval of disk, also can calculate the average access interval of disk in a certain Preset Time section, that is, and average access interval=all access interval/interval number.Equally, average access interval also can be used for describing the frequent degree of access of disk,, when average access interval is less than or equal to predetermined interval threshold value, accesses frequent degree high that is, when average access interval is greater than predetermined interval threshold value, accesses frequent degree low.Or, by the average access interval to each disk, sort to distinguish the frequent degree of access of disk.
In addition, can also obtain by other mathematics differentiation mode the parameter that other can describe the frequent degree of access, will not enumerate here.It should be noted that, default frequency threshold value, default interval threshold and default frequency threshold can be set arbitrarily according to actual needs by user, and technical solution of the present invention is not specifically limited.
Also it should be noted that, Preset Time section also can be set arbitrarily according to actual needs by user, and it can be the time interval between current once statistics and last statistics, consults shown in Fig. 4.Certainly, if the time interval between current once statistics and last statistics is long, it can be also a period of time wherein.In addition, can also be in this dormancy time section, from adding up for the first time, start to the current once time interval statistics.
In technical scheme of the present invention, must improve in the following manner the hit rate of focus disk: the frequent degree of access of regularly adding up disk, according to the frequent degree of the access of disk described in recent statistics, disk is divided into focus disk and non-focus disk, and by the Data Migration in non-focus disk in focus disk.Therefore, it is more frequent that this part is carried out, and the hit rate of focus disk is higher.
Preferred mode is, after receiving the data operation request of main frame transmission, or, often carry out after a data manipulation, just add up the frequent degree of access of a disk, and according to the frequent degree of the 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 in focus disk.
Step 202: the data operation request sending in the period at disc dormancy in response to main frame, determine described data operation request for by service data at described focus disk or in described non-focus disk;
Step 203: if determine described by service data in described focus disk, only wake up describedly by the focus disk at service data place, described in the focus disk waking up carried out to corresponding data manipulation by service data.
Step 204: if determine described by service data in described non-focus disk, only wake up described by the non-focus disk at service data place, described in the non-focus disk waking up carried out to corresponding data manipulation by service data, and by the Data Migration in the non-focus disk waking up in described focus disk.
In the present embodiment, focus disk and non-focus disk disc dormancy in the period all in dormant state.Because focus disk can be accessed continually, therefore, except this implementation, can be also focus disk disc dormancy in the period in wake-up states, and only allow non-focus disk disc dormancy in the period in dormant state.In this case, in step 203, can omit and wake this step of focus disk up.
Finally it should be noted that, in technical solution of the present invention, data operation request comprises data read request and data write request.
For example, main frame sends data read request at disc dormancy in the period, if this data read request for be read data in focus disk, only wake the focus disk that is read data place up, then read the data that are read in the focus disk waking up.If this data read request for reading out data in non-focus disk, only wake the non-focus disk that is read data place up, then read the data that are read in the non-focus disk waking up.
As can be seen from the above-described embodiment, compared with prior art, the invention has the advantages that:
At disc dormancy in the period, once main frame frequently has data operation request, as a rule, these data operation request for data all derive from focus disk, and, only need to frequently wake focus disk up, thereby can ensure the dormant state (and can not wake continually all disks up) of non-focus disk, finally realize energy-conservation effect.
Embodiment bis-
In above embodiment mono-, consider the feature that focus disk is accessed frequently, a kind of preferred mode is, unified arrange focus disk disc dormancy in the period all the time in wake-up states.
And in the present embodiment, consider if focus disk all the time in wake-up states, cannot embody better energy-conservation effect, after the frequent degree of the access of having added up each time disk, according to the frequent degree of the access of focus disk, decide focus disk is now once in wake-up states or in dormant state in the time period before statistics in distance, and then realizes energy-conservation on focus disk by staging treating mode.
Refer to Fig. 5, the process flow diagram of another embodiment of its data manipulation method that is a kind of dormancy disk of the present invention, the method comprises the following steps:
Step 501: at disc dormancy in the period, regularly add up the frequent degree of access of disk, according to the frequent degree of the access of the described disk of regular statistics, disk is divided into focus disk and non-focus disk, wherein, accessing the disk that frequent degree is high is focus disk, and accessing the disk that frequent degree is low is non-focus disk;
Step 502: according to the frequent degree of the access of described focus disk arrange described focus disk in described dormancy time section in wake-up states or in dormant state;
Wherein, access frequent degree and be more than or equal to while presetting frequent degree threshold value, described focus disk is set in wake-up states, access frequent degree and be less than while presetting frequent degree threshold value, described focus disk is set in dormant state.
It should be noted that, default frequent degree threshold value can be set arbitrarily according to actual needs by user, and technical solution of the present invention is not specifically limited.
For example, as shown in Figure 4, after statistics for the second time, if be greater than default frequent degree threshold value according to the frequent degree of access of the determined focus disk of statistics for the second time, arrange focus disk statistics for the second time with add up for the third time between the time interval in wake-up states.
Step 503: the data operation request sending in the period at disc dormancy in response to main frame, determine described data operation request for by service data at described focus disk or in described non-focus disk;
Step 504: if determine described by service data in described focus disk, judge that the described focus disk by service data place is current in wake-up states or dormant state, if in dormant state, enter step 505, if in wake-up states, enter step 506;
Step 505: wake up described by the focus disk at service data place, and to being carried out corresponding data manipulation, process ends by service data in the focus disk waking up;
Step 506: directly to being carried out corresponding data manipulation, process ends, process ends by service data in the focus disk waking up;
Step 507: if determine described by service data in described non-focus disk, only wake up described by the non-focus disk at service data place, to being carried out corresponding data manipulation by service data in the non-focus disk waking up, and by the Data Migration in the non-focus disk waking up in described focus disk, process ends.
As can be seen from the above-described embodiment, compared with prior art, the invention has the advantages that:
At disc dormancy in the period, once main frame frequently has data operation request, as a rule, these data operation request for data all derive from focus disk, and, only need to frequently wake focus disk up, thereby can ensure the dormant state (and can not wake continually all disks up) of non-focus disk, finally realize energy-conservation effect.
