Into the starting memory space of storage unit (of course, it is possible to carry depositing for particular memory space such as last several of storage unit
Store up in space), depending on marking required memory space to make the type of label；The label of storage unit also can be written into storage and set
In standby specific storage unit, that is, the storage unit for the label made an appointment for storing each storage unit, and by each storage
The label of unit is unified to be written, this label for being conducive to quickly search storage unit is preferably stored and respectively deposited in equipment
The label of storage unit is uniformly written in storage unit in the normal storage unit of status information, and so-called status information is normally
Refer to, determines that the erasable number that storage unit is supported is higher than erasable frequency threshold value based on the status information of storage unit, to avoid
The damage of storage unit leads to the label loss for storing each storage unit in equipment.
Due to label characterization be storage unit different status informations, can be using quantitatively or qualitatively marking
To describe the status information of storage unit；For using quantitative label, the state of storage unit can use from 10 to 100
Member in arithmetic sequence usually indicates that, wherein 100 indicate the state optimization of storage unit, the state of 10 mark storage units is most
Difference；
For using qualitatively label, it can be believed using health and the unhealthy state to describe a storage unit
Breath；Certainly, the status information of storage unit can also be described using multiple qualitative labels, such as using normal, dangerous, high-risk and
Damage is to describe, wherein normally indicating that storage unit supports reading, write-in and the erasing operation of normal frequency；Danger indicates storage
The erasable number that unit is supported is lower than normal value, cannot support the erasing and write-in of normal frequency, can only support that frequency is lower
Erasing and write-in；The high-risk erasable number for indicating storage unit support cannot support the erasing of data close to critical value (such as zero)
And write-in, it can only support the reading of data；Damage indicates that storage unit cannot use.
Step 303, it treats operation data to be analyzed, determines the feature to operation data.
The data operation request that storage equipment receives indicates the data for needing to operate namely to operation data and operation
Type (including reading, deletion and write-in)；Feature to operation data includes (characterizing wait grasp to the operating frequency of operation data
Make the cold and hot degree of data) and to operation data type, that is, to operation data be to need the data read, need to delete
The data data that still need to be written；Wherein, the historical operation request of the data response stored in storage unit is divided
Analysis, can determine the operating frequency to operation data that needs are written, such as a certain number stored in one or more storage units
The frequency being read according to block (file can be corresponded to).
Step 304, it based on the action type feature and/or operating frequency feature to operation data, determines with described wait grasp
Make operation grade corresponding to data.
The type of the corresponding data operation request of action type characteristic present to operation data, including including reading, deleting
It removes and is written；Operating frequency characteristic present to operation data is operated to operation data, and (as read, or updating property is write
Enter) frequency；
Binding operation type feature and operating frequency feature being capable of quantization signifying different type (data of such as read-only property, more
The data of new property write-in) operating frequency (namely cold and hot degree), the operation grade to operation data is known as in the present embodiment；
Wherein, operation grade can be using the operating frequency to operation data for describing corresponding types to qualitative mode
(such as dsc data, cold data, high cold data), wherein dsc data, cold data, high cold data characterize the operating frequency to operation data
Successively reduce；Operation grade can also using quantify by the way of describe corresponding types to operation data operating frequency (such as 1 to
Arbitrary element in 10 arithmetic sequence), wherein 1 indicates that the operating frequency to operation data is minimum (such as to the behaviour of operation data
It is read-only for making type feature, then is the minimum data of reading frequency to operation data)；10 indicate the operating frequency to operation data
Highest (being such as read-only to the action type feature of operation data, be then the highest data of reading frequency to operation data).
Step 305, the label of corresponding grade is determined based on the operation grade to operation data.
Mark grade that can correspond with operation grade, also, the label of the operation data of different operation grade is corresponding
Grade it is different；
As an example, when operation data is data to be read, the operation grade to operation data can be adopted
With the operating frequency quantization means (1-10 as the aforementioned) of data stored in the storage unit of storage equipment, correspondingly, wait grasp
The operation grade (such as 1-10) for making the quantization of data can be corresponded with the label (such as 1-10) of the quantization of storage unit,
In, 10 indicate storage units state optimization, while indicate it is associated to operation data operation grade highest (namely operation frequency
Rate highest, the dsc data as frequently read)；1 indicates that the state of storage unit is worst, while indicating associated to operation data
Operation grade it is minimum (namely operating frequency is minimum, for the high cold data read once in a while).
Equally, when operation data is data to be written, the operation grade to operation data can be set using storage
The operating frequency quantization means (1-10 as the aforementioned) of the data stored in standby storage unit, correspondingly, needless to say operation data
Operation grade can come with the label (such as 1-10) of the quantization of storage unit it is corresponding, wherein 10 indicate storage units state
It is optimal, while indicating operation grade highest (namely the frequency highest, to frequently write into the hot number to modify to operation data
According to), 1 indicates that the state of storage unit is worst, while indicating that the associated operation grade to operation data is minimum and (as writing once in a while
Enter the high cold data to modify).
As an example, when operation data is data to be read, the operation grade to operation data can be
Store operating frequency qualitative representation (dsc data as the aforementioned, cold data, the high cold number of the data stored in the storage unit of equipment
According to), correspondingly, the different operation grades to operation data can with the qualitative label of storage unit (as the aforementioned it is normal,
It is dangerous, high-risk) it corresponds；Corresponding relationship is as follows:
| Dsc data | Cold data | High cold data |
| Normally | It is dangerous | It is high-risk |
Table 1
Wherein, the state optimization of storage unit is normally indicated, while normal corresponding high fever data characterization waits for operation data
Operating frequency highest (dsc data as frequently read)；Danger indicates that the state of storage unit is worst, while corresponding height
Cold data indicates that the associated operating frequency to operation data is minimum (the high cold data as read once in a while)；
Equally, when operation data is data to be written, the operation grade to operation data can be storage equipment
Storage unit in the operating frequency of data that stores, correspondingly, the different features to operation data can use and storage
The qualitative of unit marks (normal as the aforementioned, dangerous, high-risk, wherein the storage unit damaged cannot use) to correspond to,
In, the normal state optimization for indicating storage unit, while corresponding high fever data indicate the operating frequency highest to operation data
(as frequently writing into the dsc data to modify), the high-risk state for indicating storage unit is worst, while the corresponding cold number of height
It is minimum (the high cold data to modify as is written once in a while) according to the associated operating frequency to operation data of expression.
Step 306, at least one storage with the characteristic matching to operation data is chosen based on the corresponding relationship
Unit responds the data operation request using at least one selected storage unit.
It is real by the way that the different grades of label of storage unit is corresponding with the operation grade of pending data in the present embodiment
It is on border that storage unit is corresponding to the tenability of data operation request and the different operation grades to operation data, it is sharp in this way
It can accurately be determined with corresponding relationship and support to treat the storage unit that the data processing request of operation data is responded, to keep away
Exempt from selection and does not have the storage unit treating the data processing request of operation data and being responded (as labeled as 1, damage or height
The storage unit of danger) it is responded, avoid not having the storage list responded to the data processing request for treating operation data
Member service life acceleration use up, achieve the effect that make the status information between storage unit balance (namely realize abrasion
Weighing apparatus), while ensure that the response performance to data processing request.
Embodiment three
The data to operation data that storage unit with high-level label can not only respond respective operations rank are grasped
It requests, data operation request (such as the response cold data, height lower than respective operations rank to operation data can also be responded
The corresponding data operation request of cold data)；
And the storage unit with low level label can only support the data manipulation to operation data of corresponding corresponding level
Request, cannot respond the data operation request higher than respective operations rank to operation data (such as cannot respond dsc data, height
The corresponding data operation request of dsc data), it is rapidly depleting to avoid the service life of storage unit.
The realization of two step 305 of embodiment is illustrated below based on above scheme.
As shown in figure 3, step 305 can be realized by following steps:
Step 401, at least one described storage unit is drawn using the label of at least one storage unit of the selection
It is divided into the grouping of different stage.
Wherein, the label of storage unit at least characterization storage unit supports the number of data erasing, that is, has reacted and deposited
The status information of storage unit.
As described in embodiment two, the grade of the label of different storage units is different, and the grade of label can use qualitative
Or quantitative mode is expressed as different grades, wherein the grouping of storage unit can with the grade mark one of storage unit
One is corresponding, it is of course also possible to be the grouping of the storage unit of the corresponding two neighboring or multiple grades label of a grouping；With storage
For the label of unit is indicated using above-mentioned qualitative label (normal, dangerous, high-risk as the aforementioned and damage), then storage is single
Member can be divided into normal packets, risk classification, high-risk grouping and damage grouping, as shown in the table:
Table 2
Step 402, according to the storage list of operation hierarchical selection corresponding level grouping corresponding to the feature to operation data
First response data operation requests.
Following two situation can be divided into:
1) when the characteristic present to operation data waits for that the operation grade of operation data is that low level (is set as first operation etc.
Grade) data when, choose with the grouping (groupings of same levels) of the first corresponding first level of operation grade and higher than institute
The storage unit for stating the grouping (high level grouping) of first level responds the data operation request；Wherein, described first etc.
Grade is the operation grade other than highest operation grade.
It is exemplified by Table 1, it is assumed that the operation grade to operation data corresponds to high cold data, and (corresponding first operates grade, most
Height operation grade is dsc data), the rank of grouping corresponding with high cold data operation grade is dangerous (corresponding first level),
The data operation request to operation data of storage unit response cold data operation grade of risk classification can exactly be chosen (such as
Read request), can also choose normal packets and risk classification storage unit respond high cold data operation grade to operand
According to data operation request (such as read request).
2) when the characteristic present to operation data waits for that the operation grade of operation data (is set as second operation etc. to be high-level
Grade, minimum operation grade are high cold data) when, it chooses the grouping of second level corresponding with the second operation grade and is higher than
The storage unit response data operation requests of the grouping of second level, data operation request includes data read request；Wherein, described
Second operation grade is the operation grade except minimum operation grade.
By taking the operation grade to operation data corresponds to dsc data (corresponding second operation grade) as an example, operated with dsc data
The rank of the corresponding grouping of grade is normal (corresponding second level), that is, can choose the storage unit response of normal packets
Dsc data operates the data operation request (such as read request) to operation data of grade, normally deposits since there is no being superior to
Storage unit grouping, therefore the data to operation data for only choosing the storage unit response dsc data operation grade of normal packets are grasped
Request (such as read request)；If there is (such as there is excellent grouping), then it can choose excellent grouping and normal packets answer hot number
According to the data operation request (such as read request) to operation data of operation grade.
Storage unit is grouped by the label using storage unit, can be chosen and the operation grade pair to operation data
The storage unit of rank is answered to be grouped response data operation requests, also, the grouping of high level storage unit can respond corresponding behaviour
Make the data operation request to operation data of grade and lower operation grade, and the grouping of the storage unit of low level cannot be rung
The data operation request to operation data of high operation grade is answered, this can preferentially navigate to data operation request high-level
(corresponding erasable number normal) storage unit grouping, avoid erasable number from accelerating damage close to the storage unit grouping of critical value
It is bad, abrasion equilibrium is realized, ensure that the response performance to data operation request.
