Abstract

The invention provides a distributive file system hierarchical storage method and system. The method comprises the following steps of when data to be stored is received, storing the data to be stored into a hot data storage disk under the first layer storage directory; periodically detecting the number of access times of the first storage data in the hot data storage disk; when the number of the access times of the first storage data is smaller than a preset first heat threshold value, migrating the first storage data into a cold data storage disk in the second layer storage directory; and when the proportion of the data stored in the cold data storage disk in the storage volume of the cold data storage disk exceeds the preset proportion threshold value, backing up the second storage data meeting the preset rule in a backup disk in the third layer storage directory. By using the method provided by the embodiment, data of different access quantities is stored in different layers; the use cost of the disks is controlled; and the data storage flow process of a distributive file system is simplified.

Description

technical field [0001] The invention relates to the field of distributed file system storage, in particular to a distributed file system layered storage method and system. Background technique [0002] At present, the data generated by various applications grows exponentially and explosively, and the generated data needs to be stored in the distributed file system. For data with different access frequencies, the requirements for storage hard disks are also different. For hot data with higher access frequencies, disks with higher IOPS are required, such as SSD (full name in English: Solid State Disk, full name in Chinese: Solid State Disk), high speed SAS (English full name: Serial Attached SCSI, Chinese full name: Serial Attached SCSI) disk or flash memory, and cold data with low access frequency can be stored with ordinary hard disk or tape library. [0003] However, in the prior art, it is impossible to intelligently store the data into corresponding disks according to th...
