Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
The embodiment of the present application discloses NameSpace distribution method in a kind of solid state hard disk, in the complete of same solid state hard disk
In memory space, multiple relatively independent memory spaces are created, the safety and independence of data are improved.
Referring to Fig. 1, the flow chart of NameSpace distribution method in a kind of solid state hard disk disclosed in the embodiment of the present application is such as schemed
Shown in 1, comprising:
S101: receiving distribution order, when there is idle NameSpace in the solid state hard disk, determines object naming sky
Between；
The distribution order of this step includes at least the NameSpace size of request, can also include certainly other information, example
Such as LBA (Chinese name: logical block addresses, full name in English: Logical Block Address) size, partition name, subregion
Storage format, NameSpace characteristic (such as encrypt) information in which way, are not specifically limited herein, user should be according to specific
Model, manufacturer, firmware version number and the usage of solid state hard disk make the selection of most suitable user.
User can preassign NameSpace maximum number MNN (the Max Number of in solid state hard disk
Namespaces), the value range of target namespace is from 1 to MNN, if all NameSpaces all occupy, i.e., not
There are idle NameSpaces, then cannot create new NameSpace again, return to error code, this time creation failure.It is idle if it exists
NameSpace, it is determined that target namespace, as this sub-distribution order distribute NameSpace number.
It further include the parameter judged in the distribution order after receiving distribution order as a preferred implementation manner,
It is whether legal, if so, executing when there is idle NameSpace in the solid state hard disk, determine the step of target namespace
Suddenly；If it is not, error code is then returned, this time creation failure.
S102: the NameSpace for judging whether the residual capacity in the solid state hard disk is greater than in the distribution order is big
It is small；If so, into S103；
In specific implementation, judge that this is solid after sub-distribution order distribution NameSpace number i.e. target namespace thus
Whether the residual capacity in state hard disk meets the requirement of distribution order, it is, judging whether residual capacity is greater than distribution order
The NameSpace size of request, if so, into S103, if it is not, error code is then returned, this time creation failure.
In specific implementation, can be by the idle NameSpace particle in the inquiry solid state hard disk, and judge all
Whether the size summation of the free time NameSpace particle is greater than the mode of the NameSpace size in the distribution order, judgement
Whether the residual capacity in the solid state hard disk meets the requirement of distribution order.
It is understood that also needing to judge that the remaining of solid state hard disk is held when including NameSpace characteristic in distribution order
Whether amount can support the characteristic, if so, into S103, if it is not, error code is then returned, this time creation failure.
S103: idle NameSpace particle is distributed for the target namespace, until the target namespace is big
The small NameSpace size reached in the distribution order.
In specific implementation, the memory space in solid state hard disk is distributed in the form of NameSpace particle to object naming
Unit is ordered for the idle NameSpace amounts of particles of target namespace distribution according to the size and distribution of NameSpace particle
The NameSpace size of request determines, 1 space NameSpace can be also distributed when less than 1 NameSpace granular size
Grain, until the size of target namespace reaches the NameSpace size in the distribution order.
It is NameSpace particle that this step, which defaults the minimum memory unit in solid state hard disk, therefore before this step, is needed
The solid state hard disk for being used to storing data is done into according to the characteristics of storing data the division of NameSpace particle, and be equal part into
Row divides.For example, if the solid state hard disk that total memory capacity is 100G is used to, storage volume is smaller but a fairly large number of number
According to file, then the size of suitable minimum memory unit can be set according to the mean size of the data file because GB and
Every layer of conversion multiple is all 1024 between MB and KB.For example, the mean size of the data file is all in 450K or so, and not
More than 512K, then 512K can be sized to the minimum memory unit, in order to the write-in to file and reduce every
Remaining space proportion in a minimum memory unit, then in the solid state hard disk of 100G, the preset quantity of equal part is exactly
100*1024*2=204800, i.e., the memory space of the 100G is divided into 204800 according to the mean size of storage file
Minimum memory unit, the size of each storage unit are 512K.
Certainly, the mode specifically how divided to the full storage space of a solid state hard disk is varied, most simple
Single is classified as two kinds, i.e., serially divides or parallel patition, serial division mode be one by one divide, divide
Complete one subdivided next；Parallel division mode is the division being completed at the same time to all quantity minimum memory units.This two
The kind each have their own advantage of mode and suitable usage scenario.
For example, the mean size when data file is larger, that is, the size of the minimum memory unit divided is also larger, corresponding
The quantity of minimum memory unit will be less, serial division mode can be used in the case where division numbers are less,
Because time required for partition process and the size marked off are substantially proportional, consumed using parallel division mode
Time can't be fewer than serial, and if once occurring abnormal, also only can damage a storage unit, will not draw as parallel
Point mode is likely to result in whole scrap；When the mean size of data file is smaller, that is, the size of the minimum memory unit divided
Also smaller, the quantity of corresponding minimum memory unit will be more, can be using simultaneously in the case where division numbers are more
Capable division mode can be completed to divide with higher efficiency, it is contemplated that safety and unusual condition can carry out in batches simultaneously
Row divides, without once completing total amount of division.
Only two kinds of simplest division modes above-mentioned, there is also many other division modes, based on various
Principle and method can achieve certain special effects, not make specific restriction herein, should regard actual conditions in conjunction with various shadows
The factor of sound makes the selection for being best suitable for number one.
It is understood that also being needed after this step according to the life when including NameSpace characteristic in distribution order
The characteristic of name space featured configuration target namespace.
