Abstract

The invention provides a data storage system and method. A processor determines the type of data according to the use frequency of the data, when the use frequency of the data is within a use frequency range corresponding to a first type storage hard disk, the processor determines the data as first type data, and the first type data are stored by the first type storage hard disk; when the use frequency of the data is within a use frequency range corresponding to a second type storage hard disk, the processor determines the data as second type data, and the second type storage hard disk are stored by the second type storage hard disk; and when the use frequency of the data is within a use frequency range corresponding to a third type storage hard disk, the processor determines the data as third type data, and the third type storage hard disk are stored by the third type storage hard disk, so that the data can be stored in a classified way according to the use frequency of the data. In addition, three types of storage hard disks can be added or the third type storage hard disk can be replaced at any time to store more data, therefore, the storage of the data can be improved and the loss probability of the data can be reduced without reducing the data granularity.

Description

technical field [0001] The invention belongs to the technical field of data processing, and more specifically relates to a data storage system and method. Background technique [0002] According to the research conducted by IDC (Internet Data Center) in the past five years, the global data volume doubles approximately every two years; in 2010, the global data volume entered the era of ZB (ten trillion gigabytes), and it is estimated that by 2020, the global data volume will It will reach a terrifying 35ZB. Such a huge amount of data has brought great challenges to the data storage system. [0003] At present, the data storage system adopts a distributed storage method for the storage of massive data. For example, the data storage system includes multiple servers, and each server stores part of the data in the massive data, so as to realize the distributed storage of massive data. However, as the data With the growth of data volume, multiple servers cannot bear the growing d...
