【摘要】：现如今网络技术已相当成熟,各种网络应用也层出不穷,网络应用受到了企业和个人用户的欢迎并得到了大量的应用。在这个环境下,云计算因其先进的理念和明显的优越性,被认为是网络服务发展的方向。基于云计算的网络服务成为了如今的一个热门。云存储就是这样的一个服务。目前的云存储服务提供了文件快速上传、文件历史版本回退,文件共享等服务,满足了移动办公,和数据备份等市场需求,吸引了大量的用户。但由于目前网络传输介质发展的滞后,限制了使用因特网作为数据传输通道的云存储技术的工作效率。为了规避网络数据传输慢而导致的用户无法接受的延迟,现有的云存储服务多少都要占用客户端机器上的磁盘存储空间,将部分数据存储在用户本地。这样就满足不了云存储资源只存在“云”端的特性。为了满足云存储的这个特性,本文设计并实现了一个为大型团体用户提供云存储服务的网络虚拟磁盘系统,可以在不占用用户本地存储资源的情况下保证用户能够使用一般云存储服务应用。该系统在客户端中使用了磁盘过滤驱动来实现块级别的数据传输。应用接口层使用了将应用服务器部署在局域网内的设计,来提供多个应用服务器的并行访问服务。存储层是用iSCSI协议实现的IP SAN。iSCSI作为业界的一个标准协议,其安全性和效率都由专业标准组织保证。本文详细介绍了以上技术的基础知识和实现过程,并对系统的优劣做了总结。
[Abstract]:Nowadays, the network technology has been quite mature, and a variety of network applications have emerged in endlessly. Network applications have been welcomed by enterprises and individual users and a large number of applications have been obtained. In this environment, cloud computing is regarded as the development direction of network service because of its advanced idea and obvious superiority. Cloud-based network services have become a hot topic today. Cloud storage is one such service. The current cloud storage services provide rapid file upload, file history version back, file sharing and other services, meet the mobile office, data backup and other market needs, attracted a large number of users. However, due to the lagging development of network transmission media, the efficiency of cloud storage technology using Internet as data transmission channel is limited. In order to avoid the unacceptable delay caused by the slow transmission of network data, the existing cloud storage service takes up the disk storage space on the client machine, and stores part of the data in the user's local area. This does not satisfy the cloud storage resources only exist in the "cloud" end feature. In order to satisfy this characteristic of cloud storage, this paper designs and implements a network virtual disk system which provides cloud storage service for large group users. Users can be guaranteed to use general cloud storage service applications without using local storage resources. The system uses disk filter driver in client to realize block-level data transmission. The application interface layer uses the design of deploying the application server in the local area network to provide parallel access services for multiple application servers. Storage layer is a standard protocol of IP SAN.iSCSI implemented by iSCSI protocol. Its security and efficiency are guaranteed by professional standards organization. This paper introduces the basic knowledge and implementation process of the above technology in detail, and summarizes the merits and demerits of the system.
