Abstract

The present application discloses a data migration method, device, electronic device, and computer-readable storage medium. The method includes: determining the target storage bucket for data migration based on the access heat of all storage buckets; wherein, the target storage The bucket includes a non-volatile multi-level cache medium and a hard disk drive; determine the data to be migrated based on the read / write speed of the hard disk drive and the data heat of the data in the hard disk drive; when the system time enters the protection of the target storage bucket During the time period, the data to be migrated is migrated to the multi-level cache medium. It can be seen that this application provides a data migration method, which fully utilizes the performance of various storage media in the multi-plane storage structure, distributes data on different media more reasonably during the protection period, and improves the performance of the multi-plane storage structure. Utilization of various storage media.

Description

technical field [0001] The present application relates to the field of storage technologies, and more specifically, to a data migration method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] Due to the explosive growth of data, the demand for memory capacity is increasing. The benefits brought by traditional methods of increasing cache capacity will be reduced, and frequent data exchange between internal and external memory will generate large overhead. A new type of non-volatile memory (Non-Volatile Memory, NVM) is gradually appearing in people's field of vision. Its byte-addressable, access speed is close to that of memory, and its non-volatile characteristics have a great impact on improving file system access efficiency. effect. Based on this, a multi-plane storage structure is proposed in related technologies, which can integrate NVM, SSD (Chinese full name: Solid State Drive, English full name: Solid State Disk),...
