Abstract

The invention relates to a network-based PB level cloud storage system and a processing method thereof. The network-based PB level cloud storage system comprises a main control server, a storage server cluster and a client side which are operated through an internal exchange, wherein the main control server is used for providing the directory information and the meta data information for a cloud storage client side and monitoring the storage server cluster; the storage server cluster comprises a plurality of storage servers used for data storage; the client side is used for providing the virtual disc service for a cloud storage client machine, submitting an operation request of the cloud storage client machine to a virtual disc to the main control server and reading / writing the file data from the storage server, and a client-side module is arranged on the cloud storage client machine. The invention is easy to expanded and is convenient to manage, solves the problem of storage island, can construct a cloud storage file system provided with the dynamic load balancing capability and the online backup and automatic recovery functions and capable of being expanded on demand on a general-purpose low-performance PC (personal computer) cluster.

Description

technical field [0001] The invention belongs to the technical field of mass storage, in particular to a cloud storage file system with functions of dynamic load balancing, online backup and automatic failover, and on-demand capacity expansion in mass storage, specifically a network-based PB (1PB=1024 ×1024GB) level cloud storage system and its processing method. Background technique [0002] In today's network age, storage technology is undergoing revolutionary changes. The demand that led to this revolutionary change was first manifested in the rapid expansion of storage capacity. In the era of digitalization and network interconnection, in a multi-user parallel environment, the widespread deployment of large-scale application systems poses a huge challenge to the performance and functions of mass storage systems, mainly manifested in high performance, scalability, shareability, and self-adaptation. performance, manageability, and high reliability and availability.
