Granary是一个Internet存储服务系统.和其他已有类似系统相比,Granary具有如下两个特点:①面向对象的数据管理,支持属性级的数据查询,这一点极大地方便了上层应用系统的开发;②对于系统环境的自适应性,无论在怎样的系统规模下,组成结点的动态性如何,也无论这些结点的能力分布如何,Granary都可以自动调节,取得当前系统环境下的最优性能.阐述了Granary的体系结构及主要模块的设计方法.Granary的系统实现已经完成,并在实验室范围内投入使用.计划将融入ChinaGrid提供广域存储服务.
Granary is an Internet storage service system.Compared with other similar systems, Granary has the following two features: ① object-oriented data management, support for attribute-level data query, which greatly facilitates the development of the upper application system; ② For the adaptability of the system environment, no matter what the system size, the dynamic composition of the node how, and regardless of the ability of these nodes distributed, Granary can automatically adjust to get the best performance under the current system environment Describes the architecture of Granary and the design method of the main modules.Granary’s system implementation has been completed and put into operation in the laboratory.It is planned to integrate ChinaGrid to provide wide area storage service.
