【摘要】：云计算已经成为一种崭新的IT模式,用户能够方便地通过网络按需访问可配置的计算资源。数据中心为信息服务提供运行平台,高效的云计算平台将数据中心底层的硬件资源进行虚拟化,通过统一的管理和运作方式,提供给用户和应用程序一系列的相关服务。在众多云计算平台中OpenStack作为开源项目的杰出作品,现在已经越来越受到众多设备商的重视,许多小型的互联网公司也逐渐成为了很多云计算平台的用户。OpenStack云计算平台如何能为各种不同的应用场景提供高效的服务,减少平台系统之间交互的延迟时间,以及方便有效地管理自己的计算、存储和网络等平台资源,已经成为当下云计算平台的重要问题。本文主要在OpenStack平台之下,同时结合开源分布式文件系统中的杰出作品GlusterFS,展开以下一系列工作和创新之处： (1)分析了当前云计算的技术特点和体系架构,比较了主流的开源云计算平台,深入分析OpenStack平台的基本特征、关键技术。着重分析了OpenStack平台中对象存储和块存储模块。 (2)论述了目前的分布式文件系统的发展现状,并详细分析了GlusterFS的架构、技术实现以及发展趋势,着重研究了其作为其他平台系统存储后端的优势所在,提出了选择GlusterFS作为OpenStack平台存储后端的平台设计。 (3)分析了OpenStack平台中Swift模块的作用,以及在平台系统中与其他模块的关系。利用GlusterFS的API实现了与OpenStack平台交互,并根据不同应用场景测试虚拟平台虚拟机的创建、工作和迁移等功能。借助GlusterFS的机制保证了虚拟机镜像的稳定和冗余安全保存等,并通过.FIO测试了虚拟机的读写性能指标IOPS。 (4)结合当前的云计算平台以及分布式存储的发展趋势,总结了云计算平台中存储资源管理难题,借助OpenStack平台的Cinder模块的功能,完成了基于此平台和GlusterFS的SDS (Software Defined Storage)模型。
[Abstract]:Cloud computing has become a new IT model, and users can easily access configurable computing resources on demand through the network. The data center provides the running platform for the information service. The efficient cloud computing platform virtualizes the hardware resources at the bottom of the data center and provides a series of related services to users and applications through unified management and operation. As an outstanding work of open source projects, OpenStack has been paid more and more attention to by many manufacturers in many cloud computing platforms. Many small Internet companies have also become users of many cloud computing platforms. OpenStack cloud computing platforms can provide efficient services for different application scenarios and reduce the latency of interaction between platforms and systems. And the convenient and effective management of their own computing, storage and network and other platform resources, has become an important issue of cloud computing platforms. This paper is mainly under the OpenStack platform, and combines the outstanding work of Gluster FS in the open source distributed file system, to carry out a series of work and innovation as follows: This paper analyzes the technical characteristics and architecture of cloud computing, compares the mainstream open source cloud computing platform, and deeply analyzes the basic characteristics and key technologies of OpenStack platform. The object storage and block storage modules in OpenStack platform are analyzed. In this paper, the development status of distributed file system is discussed, and the architecture, technology realization and development trend of GlusterFS are analyzed in detail, and the advantage of GlusterFS as the storage back end of other platform system is emphatically studied. This paper presents the design of GlusterFS as the storage back end of OpenStack platform. The function of Swift module in OpenStack platform and the relationship between Swift module and other modules in platform system are analyzed. The API of GlusterFS is used to realize the interaction with OpenStack platform, and to test the virtual machine creation, work and migration of virtual platform according to different application scenarios. With the help of the mechanism of GlusterFS, the stability and redundancy of virtual machine image are guaranteed, and the read and write performance index of virtual machine is tested by .FIO. Combined with the current development trend of cloud computing platform and distributed storage, this paper summarizes the difficult problems of storage resource management in cloud computing platform. With the help of the function of Cinder module of OpenStack platform, the SDS Defined storage model based on this platform and GlusterFS is completed.
