Logical partition unit；
S132：Free logical zoning unit list is created, and all logical partition units are added to free logical subregion
In unit list.
It is understood that before logical partition is created, whole solid-state disk can be uniformly divided into multiple logical partitions
Unit, the specific size of logical partition unit can be set according to being actually needed, specifically can also be by each logical partition
Unit is numbered, and is addressed according to the order of numbering from small to large for each logical partition unit.Create a free time
Logical partition unit list, before logical partition is carried out to solid-state disk, all logical partition units are not used, institute
Now can be added to each logical partition unit in the free logical zoning unit list successively, in order to not have to each
There is each logical partition unit for being partitioned and (not using) to be managed.
When user, which needs to establish, establishes logical partition to solid-state disk, you can input creates logical partition instruction, and system can
To generate ID corresponding with logical partition yet to be built according to the instruction, and then logical partition row corresponding with the ID are established according to the ID

Quantity N.Now, you can N number of logical partition unit is randomly choosed out from free logical zoning unit list, and will be selected
N number of logical partition unit is added in established logical partition list successively, so as to complete the foundation of logical partition.
For example, solid-state disk A capacity is 1G, then can be by solid-state disk A if the size of each logical partition unit is 100M
It is divided into 10 logical partition units, the numbering of each logical partition unit can be successively 0123456789, due to now not right
Solid-state disk carries out logical partition, and all logical partition units are not used, therefore can be by each logical partition unit
0123456789 is added in free logical zoning unit list, if it is patrolling for 300M that now user, which wants to set up a capacity,
Subregion is collected, then can select 3 logical partition units from logical partition unit 0123456789 at random, such as can select to patrol
Zoning unit 012 is collected, and the logical partition unit for numbering respectively 012 is added in corresponding logical partition list；If
Now user still wants to resettle the logical partition that a capacity is 200M, then can be at random from remaining logical partition unit
2 logical partition units are selected in 3456789, such as the logical partition unit that numbering is respectively 56 can be selected, now can be with
The logical partition unit for numbering respectively 56 is added in corresponding logical partition list；If user still wants to establish one
Capacity is 400M logical partition, then can select 4 logical partition lists from remaining logical partition unit 34789 at random
Member, such as the logical partition unit that numbering is respectively 3489 can be selected, and by this 4 logical partition units added to accordingly
In logical partition list.
It can be seen that logical partition unit can be randomly choosed in the embodiment of the present invention, and between each logical partition unit
Without mutually continuous, make management more flexible.In addition, added to each logical partition list in corresponding logical partition list
It can be linked between member by chained list mode, in order to when changing the size of the logical partition, patrol increase or deletion
Volume zoning unit is more convenient, and by each logical partition unit when added in corresponding logical partition list, respectively
Do not have the relation of sequencing between individual logical partition unit, can be added successively according to random order.
The embodiments of the invention provide a kind of logical partition implementation method of solid-state disk, including the establishment according to user's input
Logical partition instruction generates the ID of logical partition yet to be built, and establishes logical partition row corresponding with logical partition yet to be built according to ID
Table；According to the capacity of logical partition yet to be built and the size of logic of propositions zoning unit, it is determined that corresponding with logical partition yet to be built patrol
Collect the quantity N of zoning unit；N number of logical partition unit is selected at random from the free logical zoning unit list pre-established,
And be added to N number of logical partition unit in logical partition list successively, to obtain corresponding logical partition；Free logical subregion
Unit list establishes process as according to the capacity of solid-state disk and the size of logic of propositions zoning unit, solid-state disk is divided equally in advance
For multiple logical partition units；Free logical zoning unit list is created, and all logical partition units were patrolled added to the free time
Collect in zoning unit list.
It can be seen that the embodiment of the present invention can manage the logical partition list of free time by the list of free logical zoning unit
Member, and when establishing logical partition, can be according in the capacity of logical partition yet to be built and free logical zoning unit list
The size of logical partition unit determines the quantity of logical partition unit required in the logical partition yet to be built, and is patrolled from the free time
Collect in zoning unit list and select respective numbers logical partition unit at random, by these selected logical partition units successively
Added in corresponding logical partition list so as to obtaining corresponding logical partition.The embodiment of the present invention, carry in use
