【摘要】：我国企业经过多年信息化建设，许多设计企业内部已经具备一定的信息化规模，已经将信息网络技术以及电子商务运用到企业运营的各个环节。在这些企业中已经构建了数据管理和自动化办公等系统来提高企业的工作效率。同时，这些系统产生了大量的电子数据，，这些电子数据的存储空间、安全性、高可用性以及易管理性的需求日益突出。公有云存储的问世满足了企业大数据的存储、访问等需求。但企业级的用户由于顾虑到企业数据的安全还是远离公有云存储，私有云存储的出现，让企业级的用户开始接受云存储，且企业数据的增长有增无减，扩展的需求在未来的某个时刻必然到来，所以私有云存储环境下的具有高可扩展性的存储体系架构和高安全性是云存储研究领域中极具研究意义和应用价值的研究方向。本文主要负责私有云存储系统的容量扩展性、用户接入安全性方面研究。本文主要从两个方面进行了介绍：(1)利用了SQLite技术，建立了一个虚拟网络文件系统，实现了通过网络对分布的文件可扩展访问，完成了用户从客户端直接访问存储空间文件功能。(2)采用存储器集群技术，实现了存储空间高可用、高扩展性能，完成了存储空间的添加、删除功能。(3)设计了文件统一编码有序存放的系统，实现了用户快速、准确获取文件的功能。最后在实验室内搭建了测试环境，对系统的主机用户连入及绑定、普通用户的创建、存储池的形成及分配、存储池的可扩展性、及存储单元被移除后重新连入系统存储单元内文件是否可以继续使用的功能模块做了全面严格的测试。经过测试证明，系统成功实现了方案中设计的功能。
[Abstract]:After many years of information construction, many design enterprises already have a certain scale of information, and have applied information network technology and electronic commerce to all aspects of enterprise operation. In these enterprises, data management and office automation systems have been built to improve the efficiency of enterprises. At the same time, these systems produce a large number of electronic data, these electronic data storage space, security, high availability and manageability requirements are increasingly prominent. The emergence of public cloud storage meets the needs of big data's storage and access. But because enterprise users are concerned about the safety of enterprise data or away from public cloud storage, the emergence of private cloud storage makes enterprise users begin to accept cloud storage, and the growth of enterprise data continues unabated. The requirement of extension will come at some time in the future, so the high scalability storage architecture and high security in the private cloud storage environment is the research direction with great significance and application value in the field of cloud storage research. This paper is mainly responsible for the capacity expansibility of private cloud storage system and the research of user access security. This paper mainly introduces two aspects. (1) using SQLite technology, a virtual network file system is established, which can access distributed files through the network. The user can access the storage space file directly from the client side. The memory cluster technology is used to realize the high availability and high expansion performance of the storage space, and the addition of the storage space is completed. Delete function. 3) the system of uniform coding and orderly storage of files is designed, and the function of obtaining files quickly and accurately by users is realized. Finally, the test environment is set up in the laboratory, the host user of the system is connected and bound, the common user is created, the storage pool is formed and allocated, and the storage pool is extensible. And the function modules that the memory unit can continue to use after being removed and reattached to the system memory unit are tested thoroughly and strictly. The test results show that the system has successfully realized the function designed in the scheme.
