Abstract

The invention provides a data caching method and device. The method comprises the steps of predividing a cache link table into multiple areas, wherein the areas are used for storing data of differentpriorities respectively; after receiving data to be stored, according to the occupied length of a current link table, namely, the occupied proportion, determining the storage position of the data to be stored. The problem in the related art that the storage mode is single is solved, and files are flexibly stored in different areas according to occupied situations of the current link table.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data caching method and device. Background technique [0002] In related technologies, in the fields of large-scale distributed systems and virtualization, physical storage (usually mechanical hard disks, or disk arrays based on mechanical hard disks) is pooled for centralized management by means of software-defined storage. To achieve the purpose of on-demand allocation and elastic scaling. [0003] At this time, due to the need to cope with the pressure from different businesses at the same time, the input and output I / O speed of the mechanical hard disk often becomes the bottleneck of the system. The usual way to solve this problem is to use high-performance memory or solid-state disk as the I / O cache between the business system and the disk, and try to replace the hot data that is frequently read and written into the high-performance cache to improve the response speed o...
