Abstract

The present application relates to the technical field of data storage, and in particular, to a file migration method and device. The method is applied to a distributed storage system, and the distributed storage system includes a capacity storage pool composed of HDDs and a performance storage pool composed of SSDs, and the method includes: counting the Heads of target files stored in the capacity storage pool The access heat of the object and the snapshot object; determine whether the access heat of the Head object and the snapshot object meets the preset requirements; if it is determined that the access heat of the Head object is greater than the first set threshold, and the access heat of the snapshot object If the heat is less than or equal to the first set threshold, the Head object is migrated from the capacity storage pool to the performance storage pool, and the Head object is cloned in the capacity storage pool, and the After confirming that the cloning is complete, delete the Head object.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular, to a file migration method and device. Background technique [0002] Hard disks are the basis of distributed storage clusters, and the performance of hard disks is a key indicator for improving the IO rate of storage clusters. However, the higher the performance of hard disks, the more expensive the price and the smaller the capacity. If all high-performance hard disks ( Such as SSD), the cost of building a storage cluster is too high; however, if ordinary performance hard disks (such as HDD) are used, although the cost is controlled, the cluster IO rate is too low; therefore, the current mainstream architecture is that the hard disks of the storage cluster are composed of SSD Combined with HDD, SSD hard disks form a performance hard disk pool, which is responsible for storing data or files with high access heat; HDD hard disks form a capacity hard disk pool, whi...
