Abstract

The invention provides a data storage and dynamic migration method. The method comprises the steps that after a client side submits a data storage request, according to the size of a dispatching evaluating value, sequentially selecting at least one data node for storing data; obtaining a relative load value of the data nodes and an average load value of all the data nodes; if the relative load value of the data nodes is not smaller than the average load value, determining the data nodes as heavy load nodes, and adding the heavy load nodes into a heavy load node set in a descending sorting mode; otherwise, determining the data nodes as light load nodes, and adding the light load nodes into a light load node set in an ascending sorting mode; migrating the data in the heavy load nodes in theheavy load node set to the light load nodes in the light load node set. The execution efficiency during node load balancing can be improved, consumption of node hardware resources is lowered, and themethod is of an important and practical significance in improving the storage efficiency of a cloud storage system and relieving the bandwidth pressure.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage and dynamic migration method and device. Background technique [0002] With the rapid development of the Internet, the amount of data generated in today's society is increasing rapidly. Most of the information data on the Internet is expressed in the form of high-frequency small files, and there are relatively many operations on the storage and access of small files in the information storage and access of general users. [0003] In the cloud storage system, massive data storage, high performance, and high scalability are its main features. However, when the number of small files reaches a certain level, storing a large number of small files will bring huge pressure on the memory space of the data nodes. Frequent and repeated access to a large number of small files will also affect the performance and load balancing of data nodes. [0004] In the cloud stora...
