The invention discloses a fragmented data reading method and device and a medium, and the method comprises the steps: presetting a corresponding relation between a space occupied by each piece of data and each performance equivalent ratio, selecting at least two adjacent fragmented data from a to-be-read region as a current to-be-merged object, and under the condition that the current to-be-merged object accords with a merging condition, carrying out merging I / O operation on the current to-be-merged object. The corresponding relation between the space occupied by each data and each performance equivalent ratio is preset, so that when the I / O operation is judged to be merged or not, the performance consumption of reading the fragmented data before merging and the performance consumption of reading the fragmented data after merging can be respectively calculated through the corresponding relation, therefore, the problem of excessive consumption of bandwidth performance caused by I / O operation merging is avoided, and the overall performance of the storage system is improved.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method, device and medium for reading fragmented data. Background technique [0002] With the development of science and technology, storage systems have become an indispensable part of production practice, that is, relevant files and data in production practice are mainly stored through storage systems. However, the modification of data in the storage system and random small input / output (Input / Output, I / O) scenarios will lead to fragmentation of stored data, so it is usually necessary to read each fragmented data separately, assemble and connect them, and then store them in the storage system, so the number of fragments contained in the data area to be read depends on the number of read operations that need to be performed during the assembly process, which will greatly consume the I / O performance of the storage system. [0003] In order to reduce the I / O perform...
