对基于通用信息模型(CIM)面向NxM结构的容灾系统进行了扩展与裁剪,建立了容灾系统信息模型DTCIM。在分析CIM基础之上,详细说明了该模型的体系结构和模型内容,在Linux下基于Pegasus实现了这个信息模型,并验证了其可行性,为容灾系统的资源信息表示与管理提供了一种统一的方式,给出了容灾系统的信息模型表示方法,为进一步深入研究容灾系统打下了良好基础。
Based on common information model (CIM) for N×M structure of the disaster tolerance system, a new disaster recovery system information model DTCIM is presented by expanding and cutting the CIM. With the basic of analyzing CIM, the architecture and content model is illustrated. At the same time, the implement of DTCIM based on Pegasus is given under Linux environment. At last, its feasibility for the disaster tolerance system is tested in prototype system. A uniform method is provided to describe the disaster tolerance system resource information and manage, and deals with information model represent for further study which has laid a good foundation.
