Problems solved by technology

[0003] However, the existing technology does not combine the unique characteristics of cloud storage: the huge data volume, the number of data exceeds one billion levels, and the variety of data types, so that the transfer performance and system resource utilization have not reached a good state, resulting in Maximum Response Time Too High and Average Response Time Too High
In addition, when the cloud storage gateway provides protocol conversion services, some files will inevitably be stored on the cloud storage. If all files are stored on the cloud storage, most of the response time of the cloud storage gateway will be consumed during the actual work process. waiting for the file to download
Some cloud storage gateways have already used the cache mechanism to keep some files locally in the cloud storage gateway to reduce the average response time, but the cache replacement algorithm used by most cloud storage gateways is a commonly used cache replacement algorithm, and there is still a lot of room for further reduction average response time

Abstract

The invention discloses a cache replacement method and device, which are used for reducing the average response time of a cloud storage gateway. The method of the present invention includes: when the usage rate of the local disk is greater than the first preset threshold, sorting the files in the local disk in descending order according to the heat information of the corresponding user node, so as to obtain the file heat sorting; In the hot sorting, the last preset number of files are determined as non-hot files; remove the non-hot files from the local disk.

Description

technical field [0001] The present invention relates to the field of software storage, in particular to a cache replacement method and device. Background technique [0002] In order to promote the transformation of traditional storage to cloud storage, integrate local storage and cloud storage, and enable users to conveniently and transparently operate local data and data on cloud storage, the concept of cloud storage gateway has emerged. The function of the cloud storage gateway is mainly to convert the dedicated cloud storage interface into a traditional storage access protocol, so that users can access files on the cloud storage more conveniently, and its focus is on the protocol conversion of different file systems, that is, the cloud storage protocol and Conversion of traditional file access protocols. In order to increase the access speed of cloud storage, in the prior art, local storage can be regarded as a local cache acceleration device. [0003] However, the exis...
