Multiple user data storage service system

Abstract

This invention discloses a multi-user data storage service system including a communication module undertaking communication tasks of TCP / IP network to guarantee the compute and order transmission of data on the communication layer, a user module discriminating the access requirement of the customer end, an ISCSI protocol module transforming ISCSI and standard SCSI instructions, a multi-user document system module setting up an independent disk for every user based on the user access ways and converting the block data operation request of each user to the access to file data directly and a management module managing the above mentioned modules to coordinate their operation.

Description

technical field [0001] The invention relates to a file management system, in particular to a file management method for a multi-user data storage service system. Background technique [0002] With the continuous development of information technology, information technology is widely used in various fields, resulting in a sharp increase in the amount of information, which directly leads to higher and higher requirements for information storage, especially for enterprise-level users. With the development of the development and the increasing number of users, in order to allocate independent storage space to each user, the requirements for server hardware, especially storage hardware (mainly the storage capacity of the hard disk) are getting higher and higher, and Insufficient data management of the current storage service system results in low utilization efficiency of server storage space, which is mainly manifested in the following aspects. [0003] First of all, for a spec...

AI Technical Summary

Problems solved by technology

[0003] First of all, for a specific user, instead of allocating storage space according to the real needs of the user, a fixed storage space is allocated, regardless of whether the allocated storage space is actually effectively used, which will inevitably lead to the utilization of server storage space. low efficiency

[0004] Secondly, when the storage space of the current server assigns storage capacity to each client separately, the sum of the data storage space allocated by all clients cannot be greater than the total storage space of the server, so the storage space allocated to each client Due to restrictions, the storage space allocated to each user is not large, and the storage space of the server cannot be fully utilized

[0005] In addition, for a storage service system with a large number of users and a large data capacity, the current service file system partitions the hard disk according to the user, and allocates independent storage space for different users, which will inevitably result in the duplication of a large number of files with the same content for different users. Storage, which is a considerable waste of the limited storage space of the server, resulting in the ineffective use of the storage resources of the server
