Requirement selected.
S102：Determine file destination from the system file.
May there are one or more files in the system file higher to the performance requirement of hard disk, due to these texts
Part is defaulted as being stored in storage volume group, and compared to solid state hard disc volume group, the processing speed of storage volume group is relatively low compared with i.e. performance slowly,
So, these files can be shifted, solid state hard disc volume group can be transferred to from storage volume group, to meet these files
To the performance requirement of hard disk in invoked procedure.
Before being shifted, it is necessary to first determine which file needs to be shifted from system file, in the present invention
In implementation, will can need to carry out the staged files referred to as file destination.
Wherein, the determination mode of file destination can have various.A kind of mode can be with the frequency of use of file be according to
According to the frequency of use of certain or some files is higher in system file, illustrates that the performance in this document invoked procedure to hard disk will
Ask higher.
In actual applications, the system file number for being stored in computer is various, and many files and is not frequently used,
That is the frequency of use of these files is relatively low, without being transferred in solid state hard disc volume group, so, target is being determined from system file
During file, in order to lift the operating efficiency of computer system, unnecessary handling process in reduction computer system can be first right
System file carries out preliminary screening.Specifically, can be using the specified corresponding file of subregion or store path as predetermined
File, you can using by the specified file in system file as predetermined file, for example, can be by corresponding to certain Physical Extents
File, as predetermined file, or using the file of certain logical partition as predetermined file, or is by certain storage road
File corresponding to footpath is used as predetermined file.Such that it is able to determine file destination from the predetermined file, computer is reduced with this
System is it is determined that handling process unnecessary during file destination.
In implementing, can be by calculating predetermined file frequency of use at the appointed time；Judge described predetermined
Whether the frequency of use of file is more than high frequency threshold value, if being more than, using the predetermined file as file destination.
For example, high frequency threshold value can be used to indicate that the one of the frequency of use of the file destination being stored in storage volume group
Individual higher limit, when the frequency of use of file destination is more than the high frequency threshold value, illustrates that the performance of now storage volume group cannot
The file destination is met, it is necessary to file destination is transferred in solid state hard disc volume group.
Often have multiple in view of the file number included in predetermined file, in order to ensure to include in predetermined file each
File under same standard, can be specified by setting in embodiments of the present invention in the frequency of use of calculation document
Time, the frequency of use of each file for thus calculating is the frequency of use of the file in stipulated time section.
Wherein, the number of times that the frequency of use of file can be called by file reflects, can be pre- in implementing
Each file for determining to be included in file sets corresponding counter, is called for counting the predetermined file at the appointed time
Number of times, the frequency of use of the predetermined file is equal to number of times that the predetermined file is called divided by the stipulated time.
The length of the stipulated time can determine according to actual requirement, not limit herein.In view of in the different time
In section, the frequency of use of file it may happen that change, so, in the present invention is implemented, the stipulated time can regard one as
Individual cycle time, for example, will be set to the stipulated time 10 seconds, computer system can be every 10 seconds, to being included in predetermined file
Each file carry out the calculating of first use frequency.By taking a file as an example, this document in a stipulated time has often been calculated
Frequency of use after, the counter of this document can automatic clear, count file in next stipulated time again with this and adjusted
Number of times.
In addition to the mode for determining file destination above by the frequency of use of calculation document, in the present invention is implemented,
The form that can be identified by add file, is its addition high frequency text for example, some files can be selected by artificial mode
Part is identified.Computer system can be by judging whether the predetermined file has high frequency file identification；If the predetermined file
With the high frequency file identification, then using the predetermined file as file destination.
S103：The file destination is moved or copied to the solid state hard disc volume group from the storage volume group, and by institute
The path for stating solid state hard disc volume group is set to the accessed path of the file destination.
File destination can be understood as the file higher to the performance requirement of hard disk, or perhaps the class file is frequent
Call, it is necessary to store the hard disk of the class file with processing speed faster, compared to storage volume group, solid state hard disc volume group has
Performance higher, so, file destination can be moved or copied to the solid state hard disc volume group from the storage volume group, with this
Meet the high performance requirements of file destination.
By by file destination from as a example by moving to the solid state hard disc volume group from the storage volume group, the now file destination
It is stored in solid state hard disc volume group, the file destination has not been included in storage volume group, due to general meeting default document in system
It is stored in storage volume group, therefore, when this document is called, can be according to the path searching of the acquiescence file destination.In view of general
The purpose that file destination moves in solid state hard disc volume group is that computer system can call the mesh from solid state hard disc volume group
Mark file, performance requirement when file is called to hard disk is met with this.So, moved from the storage volume group by file destination
Move after the solid state hard disc volume group, it is necessary to the path of solid state hard disc volume group to be set to the accessed path of the file destination,
The accessed path of setting can be dependent in order to computer system call the file destination from solid state hard disc volume group.
When the memory space of storage volume group is larger, it is also possible to copy the file destination to institute from the storage volume group
Solid state hard disc volume group is stated, now file destination had both been present in storage volume group, in existing in solid state hard disc volume group.Need explanation
, when the file destination is included in solid state hard disc volume group, the path of the solid state hard disc volume group can be set to institute by system
The accessed path of file destination is stated, now system is only processed the file destination by solid state hard disc volume group.
In embodiments of the present invention, the volume group of solid state hard disc volume group and storage volume group both types can be set up, for
Each type of volume group, its number may have one or more, by taking solid state hard disc volume group as an example, when the number of the volume group is multiple
Situation, when file is stored, can determine which file is stored in by pre-setting the storage rule of file
In volume group, for example, file can be stored in a maximum volume group of memory capacity using the memory capacity of volume group as foundation,
After volume group storage is full, then successively to the storage of other volume groups.
By above-mentioned technical proposal as can be seen that computer system can set up solid state hard disc according to the volume group rule for setting
Volume group and storage volume group, wherein, solid state hard disc volume group is only made up of solid state hard disc, to ensure the high-performance of solid state hard disc.Compare
In solid state hard disc volume group, the unit memory capacity price of storage volume group is relatively low, namely the carrying cost of storage volume group is relatively low, calculates
The system file of machine can be initially deposited in storage volume group, by determining file destination from system file, the class file
Performance requirement to hard disk is higher, or perhaps the class file be called frequently, it is necessary to store the class file hard disk have compared with
Fast processing speed, because solid state hard disc volume group has performance higher, so, can be by file destination from the storage volume group
The solid state hard disc volume group is moved or copied to, and the path of the solid state hard disc volume group is set to looking into for the file destination
Path is looked for, the high performance requirements of such file destination are met with this.It can be seen that, by above-mentioned technical proposal, can give full play to solid
The advantage of state hard disk and mechanical hard disk, the file low for hard disk performance requirement is stored in storage volume group, for hard disk performance
It is required that file high can be moved or copied in solid state hard disc volume group, so as to effectively lift solid state hard disc and mechanical hard disk
Service efficiency.
Change over time, the frequency of use of file is it may happen that change, solid state hard disc is stored in by file destination
The purpose of volume group is the performance requirement for meeting the file destination, the use of the file destination in solid state hard disc volume group is stored in
After frequency reduction to a certain extent, now, the performance of storage volume group can meet the requirement of the file destination, not have
Necessity continues the file destination to be stored in the solid state hard disc volume group.
In this case, use of the file destination in Preset Time can be calculated by setting Preset Time
Frequency；When the frequency of use of the file destination is less than or equal to low frequency threshold value, then by the file destination from the solid-state
Hard disk volume group is moved back to the storage volume group, and the path of the storage volume group is set to the accessed path of the file destination.
Calculate frequency of use of the file destination in Preset Time with above-mentioned calculating file destination making at the appointed time
It is similar to the calculation of frequency, is will not be repeated here.
Wherein, low frequency threshold value can be used to indicate that a lower limit of frequency of use of the file destination in solid state hard disc volume group
Value, when the frequency of use of file destination is less than or equal to the low frequency threshold value, illustrating the performance of storage volume group can meet the mesh
Mark file, therefore the file destination can be moved back into storage volume group.
It should be noted that the length of Preset Time can determine according to actual demand, wherein, the specific number of Preset Time
Value can be identical with the concrete numerical value of above-mentioned stipulated time, it is also possible to different, does not limit herein.With above-mentioned stipulated time class
Seemingly, the Preset Time can also regard a cycle time as, for example, Preset Time is set to 10 seconds, computer system can
Every 10 seconds, the calculating of first use frequency is carried out to file destination, until the frequency of use of file destination is less than or equal to
Low frequency threshold value.
With above-mentioned for file addition high frequency file identification is similar, for the file being stored in solid state hard disc volume group, also may be used
It is its addition low frequency file for example, some files can be selected by artificial mode in the form of being identified by add file
Mark.
After Preset Time is reached, computer system can be by judging whether the file destination has low frequency files-designated
Know；
If the file destination has the low frequency file identification, by the file destination from the solid state hard disc volume group
The storage volume group is moved back to, and the path of the storage volume group is set to the accessed path of the file destination.
It is different to the mode of solid state hard disc volume group from storage volume group transfer (mobile or copy) for file destination, by target
The mode that file is moved back into the storage volume group from the solid state hard disc volume group is also different.
So that file destination moves to solid state hard disc volume group from storage volume group as an example, when the frequency of use of file destination is less than low
Frequency threshold value, or file destination is when having low frequency file identification, then can be by the file destination from the solid state hard disc volume group
Move to the storage volume group.
When file destination copies solid state hard disc volume group to from storage volume group, when the information included in file destination
When changing, the file destination stored in solid state hard disc volume group can be carried out in real time more according to the change of information in file
Newly, and in storage volume group the information included in the file destination for storing is still the content before being copied.Namely work as target
File copy is current newest file destination to what is after solid state hard disc volume group, stored only in solid state hard disc volume group.Therefore, when
The frequency of use of file destination is less than low frequency threshold value, or file destination when there is low frequency file identification, it is necessary to by the target
File is moved back in storage volume group in the way of covering and writing back from the solid state hard disc volume group.
Because after file destination to be stored in solid state hard disc volume group, computer system can be by the path of solid state hard disc volume group
The accessed path of the file destination is set to, therefore, after file destination is moved back into storage volume group from solid state hard disc volume group, need
Path before the accessed path of the file destination is reduced to, i.e., be set to the target by the path of storage volume group again
The accessed path of file.
