LBA allocation method, device and equipment, and readable storage medium

Abstract

The invention discloses an LBA allocation method, device and equipment and a readable storage medium. The method disclosed by the invention comprises the steps of obtaining to-be-stored I / O data; judging whether the data size of the I / O data exceeds a preset threshold value or not by utilizing a logistic regression algorithm; and if so, processing the I / O data by using a linear regression algorithm to obtain continuous LBA identification information, and allocating continuous LBAs to the I / O data according to the continuous LBA identification information. According to the invention, continuousstorage of large I / O data in a physical space can be realized, and troubles are not brought to addressing of subsequent read-write operation. And the logistic regression algorithm and the linear regression algorithm can also improve the accuracy and efficiency of LBA allocation. Correspondingly, the LBA distribution device and equipment and the readable storage medium disclosed by the invention also have the above technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an LBA allocation method, device, equipment and readable storage medium. Background technique [0002] At present, when storing I / O data, the LBA (Logical Block Address, logical block address) is randomly assigned to the I / O data, which can take into account the LBAs in the rear order, so that the LBAs in the rear order correspond to Data can also be written in the physical space, so that there is no situation where data is written repeatedly in some physical spaces, but there is always no data written in some physical spaces. However, in the process of randomly allocating LBAs, it is necessary to divide the large block of I / O data into small particles, which will result in scattered storage of the original block of data, which is not conducive to the addressing of subsequent read and write operations. [0003] Therefore, how to reasonably allocate LBAs for I / O d...

Problems solved by technology

However, in the process of randomly allocating LBAs, it is necessary to divide the larger block of I / O data into small particles, which will cause the original whole block of data to be stored scattered, which is not conducive to the addressing of subsequent read and write operations.
