Problems solved by technology

[0002] In many existing network projects, customers need to copy massive data from old storage devices to hot data pools in new storage devices; generally speaking, hot data pools have better data storage performance than cold data pools, Generally, hot data pools are composed of SSD and other media, which are expensive compared to disks, and the capacity of hot data pools is limited; some existing distributed file storage systems have a hierarchical migration function, which can be used without the user's perception. Migrate data from hot data pools to cold data pools to meet the needs of users on site, but currently distributed storage devices do not support hierarchical migration and support for multiple data pools

Abstract

The invention provides a multi-data-pool hierarchical migration method and system. The method comprises steps of setting multiple data pools in an original migration strategy, configuring the IDs of the multiple data pools, and enabling the multiple data pools to comprise a hot data pool and a plurality of cold data pools; analyzing the multiple data pools and verifying whether the ID is legal ornot; grading a plurality of cold data pools according to the residual capacity; and selecting a target data pool according to the grading situation, and migrating the data files in the hot data pool to the target data pool. According to the method, the function of multiple data pools migrated by the distributed storage system is used, the data of the hot data pool can be directly migrated to the multiple cold data pools according to the strategy, and that new data and old data are automatically balanced in the multiple data pools is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of distributed storage, and in particular relates to a method and system for hierarchical migration of multiple data pools. Background technique [0002] In many existing network projects, customers need to copy massive data from old storage devices to hot data pools in new storage devices; generally speaking, hot data pools have better data storage performance than cold data pools, Generally, hot data pools are composed of SSD and other media, which are expensive compared to disks, and the capacity of hot data pools is limited; some existing distributed file storage systems have a hierarchical migration function, which can be used without the user's perception. Migrate data from hot data pools to cold data pools to meet the on-site needs of users, but currently distributed storage devices do not support the function of hierarchical migration and support for multiple data pools. Based on this, the present i...
