Embodiment 1

[0037] A dynamic copy management method based on file popularity, the entire system adopts a distributed architecture, distributed file storage systems such as figure 1 As shown, it includes a main management server 1 and a storage server cluster 2. The main management server 1 is used to accept user file access requests and update the access records of accessed files. The storage server cluster 2 includes a plurality of storage servers for storing files. storage server3. The distributed file storage system supports large-scale high-concurrency access and dynamic expansion of cache server clusters. The main management server 1 can eliminate single points of failure through dual-system hot standby. The main management server 1 manages the storage nodes and storage nodes in the storage server cluster 2. Metadata information of files in the storage system. The storage server cluster 2 implements the function of dynamically loading and deleting nodes to provide dynamically scalab...

Abstract

The invention relates to the field of computer application, and discloses a dynamic replica management method based on file heat. The method comprises a main management server and a memory server cluster, wherein the main management server is used for receiving user file access requests and updating access records of the accessed files, and the memory server cluster comprises a plurality of memory servers used for storing files. The dynamic replica management method comprises the specific steps of a multi-frequency file heat computing mechanism, a multi-queue file heat updating mechanism, and a multi-frequency replica execution mechanism. The dynamic replica management method has the advantages that the problems of contradiction between the file heat statistic period and the heat statistic accuracy, and sudden user access are solved effectively, the system spending is reduced greatly, and higher reliability is provided simultaneously.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a dynamic copy management method based on file heat. Background technique [0002] Traditional data storage technologies are far from meeting today's data storage needs in terms of scalability and high availability. In the 1980s, the concept of distributed file storage was proposed. [0003] Distributed file storage refers to some physical storage resources that are not necessarily directly connected to the local nodes. They are connected to the nodes through the computer network and are managed by the storage system in a unified manner. They provide users with a unified and object-oriented access interface and shield the access to physical devices. Direct manipulation and resource management. The distributed file storage system supports the storage of massive file data through a distributed architecture. Through distributed file storage, various storage devices can be used...
