Request processing method, device and equipment and readable storage medium

The invention belongs to the technical field of storage, and particularly discloses a request processing method, device and equipment and a readable storage medium, and the method comprises the steps: dividing a file into a plurality of blocks for storage in a file system; receiving and analyzing the block IO request to obtain a target block requested to be accessed; if the target block is located in the slow pool, converting the block IO request into a storage IO request and a block migration request, and responding to the block migration request and the storage IO request; and if the target block is located in the fast pool, converting the block IO request into a storage IO request, and responding to the storage IO request. Due to the fact that the data accessed at high frequency are only a small part of data, when the file is stored, the file is divided into a plurality of blocks to be stored. According to the method and the device, the data classification is carried out based on the IO request, and the hi
