Data copy mapping method and device based on object-oriented file system

Abstract

The invention discloses a data copy mapping method based on an object-oriented file system and a device thereof; the invention can support the data copy technology and achieve the purpose of fast mapping with a simple and effective method. The data copy mapping method based on the object-oriented file system which is provided by the embodiment of the invention comprises: the only object mark for the object of an object-oriented file system is mapped to a first data space; each storage node is configured with an only storage node mark and grouped and the storage node mark is mapped to a second data space; the destination storage node of the data copy of the object in each group is determined, and the difference value between the mapping value of the destination storage node in the data second space and the mapping value of the object in the first data space is a minimum. The data copy mapping device based on the object-oriented file system which is provided by the embodiment of the invention includes an object mapping module, a data copy mapping control module, and a storage node group mapping module.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data copy mapping technology based on an object-oriented file system. Background technique [0002] With the continuous advancement of network technology, the amount of network data is increasing day by day, and mass data storage has become one of the problems that need to be solved urgently in the development of the network. The network storage system provides information access service and information sharing service of the network information system. Its super large data capacity, super high data transmission rate and super high system availability have become the typical characteristics of network storage, and the object-oriented file system has become a network storage system. development trend. Object-oriented storage means that data is stored in units of objects. An object is actually a combination of file data and a set of attributes that can define file-based red...

AI Technical Summary

Problems solved by technology

Due to the decreasing price of storage node resources, storage node resources in large-scale storage systems are relatively abundant, and data copy technology has become a popular technology to ensure the reliability of data storage, which requires that the data mapping method must effectively support data copy technology; and As the scale of the storage system increases, the addition and failure of storage nodes will become more frequent. Failures include storage node withdrawal and damage, making the reliability maintenance of the storage system more and more difficult.
