存储网格资源管理系统的研究与实现
摘要
网格是继传统互联网、Web之后的第三个大浪潮,可以称之为第三代互联网应用。网格计算实际上是构筑在Internet上的一组新兴技术,其目标是在动态变化的、广域分布的异构虚拟组织间实现协同资源共享。本文从介绍网格的基本概念开始,简述了什么是网格、网格的体系结构及各层次的作用和相互关系,并比较了国内外网格的发展情况。接着阐述了目前最具影响力的网格中间件Globus的体系结构和系统结构,并介绍了Globus项目实现的主要部分:网格安全基础设施-——Grid Securitu infrasture(GSI)、Globus资源分配管理——GtobusResource Allocation Manager(GRAM)等,着重分析了资源发现及触发系统——Monitoring and Discovery Service的实现原理及方法。
建设校园存储网格首先要解决资源监测与资源触发问题。资源监测为其他的网格中间件提供必要的与资源有关的性能数据,是资源发现和任务分配的基础。资源触发功能的强弱直接决定了存储网格的使用效率。
本文在对网格研究的基础上,提出了建设存储网格应注意的问题,着重研究了资源监测与触发基本理论和相关技术,提出了资源监测与触发的方法,结合校园存储网格本身的特点,给出了建设校园计算网格应实现的功能,分析了资源监测与触发服务在校园计算网格模型中的地位,最后设计实现了校园存储网格资源监测与触发服务。
The Grid has become the third popular technologic wave after the traditional internet and web. It is called the third generation application of internet. Actually Grid computing has emerged as a new important technology upon the internet. It is orientated to coordinated resource sharing in dynamic and multi-institutional virtual organizations.In this paper,we introduce some basic knowledge of Grid computing,such as what Grid is.And the important component in Globus Project are:Grid Security infrastructure(GSI),Globus Resource Allocation Manager (GRAM),especially the Monitoring and Discovery Service (MDS)in Globus Project.
Resource monitoring and trigger is the base of the Campus Store Grid since it will offer the necessary resource information to other grid middleware.The power of resource monitoring and trigger system will strongly and directly affect the degree of the grid usage efficiency.
Based on the research of grid,the attentive problems are brought forward.This paper introduced the basic principle and also related techniques and methods of resource monitoring and trigger.Based on the characteristics of campus store grid,there is a discussion about important functions of campus store grid which should be realized and,analysis of the position of the resource monitoring and discovery service in the store grid.Fanally,the services of campus store grid's resource monitoring and trigger have been realized.
