摘要

针对面向企业的数据网格应用

给出了平民数据网

格DGHB的概念

并提出了针对DGHB网格的一种基于存储联盟的双层动态副本创建策略—SADDRES.通过在数据网格模拟工具OptorSim中的模拟

分析、比较了SADDRES策略与基于缓存的副本创建策略、基于经济模型的副本创建策略等多种策略的性能.实验结果表明

SADDRES策略在面向企业的数据网格应用中具有更好的系统性能.

Abstract

Data Replication technologies have been widely applied in data grid systems to improve the performance of grid applications

and replica creation strategy is one of the key technologies of Data Replication.A new concept Data Grid of Humble Birth (DGHB) is proposed for enterprise-oriented data grid applications.And a replica creation strategy - Storage Alliance based Double-layer Dynamic Replica crEation Strategy (SADDRES) is also proposed.The simulation results on OptorSim prove that the SADDRES is more efficient than other replica creation strategies for enterprise-oriented data grid applications.
