一种基于CloudSim的分级云存储仿真模型

A CloudSim-based Hierarchical Cloud Storage Simulation Model

随着云存储技术的发展,云存储平台解决了大数据存储与管理的难题。然而当数据量与用户量进一步扩大,系统性能要求逐步提升,需要对目前云存储环境中的数据存储管理技术进行深入的研究与改进。由于应用实际的云存储集群进行优化研究极易受到平台环境的限制,因此基于CloudSim实现了一个分级云存储的仿真模型TCSS,给出了一种三层次的设备分级组织结构,构建了完善的数据I/O业务处理与数据存储管理等功能结构。已经将所有拓展功能模块集成到了CloudSim仿真工具的CloudSim层中,用户可以依据TCSS模型,突破平台限制,完成云存储优化策略的建模与测试工作。

With the development of cloud storage technology,the cloud storage platforms meets the storage and management requirements of big data.However,when the amount of data and the number of users are further expanded,the system performance requirements of cloud storage are gradually improved,and the data storage management technology in the current cloud storage environment needs to be deeply researched and improved.Considering that the application of the actual cloud storage cluster for optimization research is very vulnerable to the platform environment,this paper implements a hierarchical cloud storage simulation model named TCSS in CloudSim,while implements a three-level hierarchical organization structure of storage devices,then the functional structure such as data I/O service processing and data storage management has been established.In this paper,all the extended function modules have been integrated into the CloudSim layer of the CloudSim simulation tool.Based on the given TCSSmodel,Users can complete the modeling and testing of the cloud storage optimization strategy proposed by themselves.
