Embodiment Construction

[0097] In order to make the purpose, technical solution and advantages of the present invention clearer, a method and system for controlling data storage in a cluster file system of the present invention will be described below in conjunction with the accompanying drawings and embodiments. For further details. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0098] A data storage method and system in the control cluster file system and a file creation method of the present invention are to migrate data by collecting and measuring the load of the storage system in real time, so that the I / O access load between storage nodes in the storage system is between Balanced state, and no storage node's disk space utilization is saturated. It can make full use of the disk bandwidth of all storage nodes, maximizing the aggregation performance of the storage system.

Abstract

The invention discloses a method and a system for controlling data storage in a cluster file system and a method for creating a file. The cluster file system stores files by grouping storage nodes. The method for data storage comprises the following steps of: collecting and measuring binary load information containing I / O access load space utilization rate of each storage node in the cluster file system during interval period; measuring whether the load of the cluster file system is balanced or not according to the binary load information of each storage node; and migrating data of in cluster file system if the load of the cluster file system is not balanced.

Description

technical field [0001] The invention relates to the storage system structure field of a cluster file system, in particular to a method and system for controlling data storage in a cluster file system and a file creation method. Background technique [0002] With the development of cluster technology, cluster computing is not limited to traditional high-performance computing-based scientific computing fields such as high-energy physics research, site exploration, and climate simulation analysis. The current cluster computing is more used in commercial applications, such as finance, telecommunications, and Internet information services. For the above-mentioned applications, not only a large number of computing resources are required, but also a large number of data storage and access operations are required. [0003] Whether it is in scientific computing applications, commercial applications, or Internet information services, the file size of the data generated by the applica...
