Description
Technical Field
The present invention relates to the field of storage, and in particular, to a method and an apparatus for writing data.
Background
The solid state disk is composed of a main control unit and a solid state storage unit, and the solid state storage unit comprises a plurality of blocks, namely data blocks. Because the solid state disk has no rewriting mechanism, after a Block is full of data, the data in the Block needs to be erased, and new data can be written.
While the erase operation is very time consuming. In consideration of efficiency, when a user writes the same logical address, the solid state disk actually writes the same logical address into different physical addresses, which causes the situation that invalid data exists on an original address, and garbage collection is required to improve the space utilization rate.
Garbage collection is a data transfer technique for transferring valid data in a block in which invalid data and valid data are mixed to a new block in order to collect an available space, thereby freeing up the space occupied by the invalid data. However, the valid data of garbage collection and movement is closely related to the data writing mode of the user, and is difficult to predict, so that the speed of garbage collection and block recovery is suddenly fast and slow. When the storage space of the solid state disk is insufficient, a user writing operation needs garbage collection to provide a space, the garbage collection needs to write previous user data, and data writing needs to wait for the space given by the garbage collection, so that the writing performance of the user is affected by the garbage collection.

The embodiment of the invention provides a data writing method and related equipment, which are used for buffering the influence of low garbage recovery efficiency on the writing performance of a user.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The following describes a method of writing data from the perspective of a data writing device, which may be a server or a functional unit in the server, and is not particularly limited.
Referring to fig. 1, fig. 1 is a schematic diagram of an embodiment of a data writing method according to an embodiment of the present invention, including:
101. and judging whether the space of unwritten data in the target storage device is smaller than a first threshold, if so, executing the step 102, and if not, executing the step 106.
In this embodiment, when data needs to be written to a target storage device (for example, a solid state disk), at this time, a space of unwritten data in the target storage device may be first obtained, and it is determined whether the space of unwritten data in the target storage device is smaller than a first threshold (for example, 100M), if yes, step 102 is executed, and if no, step 106 is executed. The target storage device is a storage device to which data is to be written, that is, it is necessary to determine whether a storage space in the target storage device is sufficient before writing the data.
102. And starting garbage collection on the target storage device.
In this embodiment, when it is determined that the space of unwritten data in the target storage device is smaller than the first threshold, garbage collection is started for the target storage device, where garbage collection is a data moving technology for moving valid data in a block in which invalid data and valid data are mixed to a new block in order to collect an available space, so as to vacate a space occupied by the invalid data. That is, garbage collection is a technique of moving valid data in a block to a new block and erasing invalid data in the original block.
103. And acquiring the target speed of garbage recovery.
In this embodiment, a target speed of garbage collection may be obtained, where the target speed is an erasing speed of an invalid speed in a target storage device, and the target speed is closely related to a mode of writing data by a user, that is, if data stored in the storage device is dispersed into all blocks, that is, there is a possibility that invalid data exists in each block, when garbage collection is performed, a time for releasing a new block is relatively long, and a corresponding target speed is relatively low. Here, the mode of acquiring the target speed of garbage collection is not particularly limited.
104. And judging whether the target speed is higher than a second threshold value, if so, executing step 106, and if not, executing step 105.
In this embodiment, after the target speed for garbage collection is acquired, it may be determined whether the target speed is higher than a second threshold, when the target speed is higher than the second threshold, step 106 is executed, and when the target speed is lower than the second threshold, step 105 is executed.
105. And writing the data to be written into the blocks of the target storage pool.
In this embodiment, when the target speed is lower than the second threshold, the data to be written may be written into a block in the target storage, where the target storage pool is preset, and the target storage includes at least one block in which data is not written, and the at least one block in which data is not written is a block in the target storage device.
It should be noted that, when the target storage device is initialized, the target storage pool having an association relationship with the target storage device is established. That is, when the target storage device is initialized, all blocks in the target storage device are numbered, and a part of the numbers are taken out to form the target storage pool. The target storage pool is only a number logically comprising blocks, and the blocks in the target storage device are actually still in place. That is, in step 105, the data to be written is written into the block corresponding to the number stored in the target storage pool.
It is further noted that the initial number of blocks in the target storage pool has an associated relationship with the number of blocks in the reserved area of the target storage device. The target storage device comprises two areas, wherein the first area is a reserved area, the second area is a user area, the space of the reserved area is a space which is not open to a user and is used for storing data required by the operation of some storage devices, and the space of the user area is a space which is open to the user, namely the size of the space displayed by the storage devices in practice. The number of initial blocks in the target storage pool has an associated relationship with the reserved area, and if the reserved area occupies 1/5 of the target storage device space, the number of blocks in the target storage pool may be set to 20. The above values are for illustration and do not represent a limitation on the number of blocks in the reserved area and the target storage device.
106. Other operations are performed.
In this embodiment, when the space of the unwritten data in the target storage device is larger than the first threshold, the data to be written may be directly written into the target storage device. When the target speed is higher than the second threshold, a preset number of blocks may be stored in the target storage pool, where the preset number of blocks are blocks in the target storage device for which data is not written. That is, when the efficiency of garbage collection is higher than the second threshold, which is set to have an association relationship with the data writing speed of the target storage device, for example, the second threshold is the same as the data writing speed of the target storage device (although other settings may be used, here, the second threshold is set to be the same as the target storage device), when the target speed is higher than the second threshold, that is, the garbage collection speed is higher than the data writing speed, the numbers of some blocks in the target storage device that have not written data can be put into the target storage pool for standby at this time, so as to prevent the numbers of the blocks in the target storage pool from being taken out for use by the user when the garbage collection speed is low at the time of subsequent data writing.
In summary, in the embodiment of the present invention, because the target storage pool is set in advance in the target storage device, when the speed of garbage collection is lower than the second threshold, the data to be written is directly written into the block in the target storage pool, and when the speed of garbage collection is higher than the second threshold, a part of the blocks without writing data can be placed into the target storage pool, so as to prevent the number of the blocks in the target storage pool from being taken out for the user to use when the speed of garbage collection is low during subsequent data writing, thereby buffering the influence of the garbage collection efficiency on the performance of the data written by the user.
The embodiments of the present invention are described above from the viewpoint of a method of data writing, and the embodiments of the present invention are described below from the viewpoint of a data writing apparatus.
Referring to fig. 2, fig. 2 is a schematic diagram of an embodiment of a data writing apparatus according to an embodiment of the present invention, the data writing apparatus is applied to a storage device, and includes:

Optionally, the apparatus further comprises:
an establishing unit 206, configured to establish the target storage pool having an association relationship with the target storage device when the target storage device is initialized.
Optionally, the apparatus further comprises:
and a storage unit 207, configured to store a preset number of blocks into the target storage pool when the target speed is higher than the second threshold, where the preset number of blocks is a block in which data is not written in the target storage device.
