Document Type and Number:

WIPO Patent Application WO/2021/036329

Kind Code:

A1

Abstract:

Disclosed in embodiments of the present application are a data storage method and apparatus. The method is applied to a storage device, and the storage device comprises at least two storage pages with different read and write delays. In the method, first data and delay level identification of the first data are first acquired; thereafter, a first storage page corresponding to the delay level identification is determined according to a correspondence between different types of storage pages and the delay level identification, and then the first data is written into the first storage page. By means of the present application, data can be stored according to the different read and write delays of various storage pages comprised in the storage device. That is to say, in the solution disclosed in the embodiments of the present application, by using the differences of the read and write delays of various storage pages in the storage device, only one storage device needs to be provided in a hierarchical storage system to achieve hierarchical storage, thereby solving the relatively complicated configuration problem of existing hierarchical storage systems.
