【摘要】：随着现代网络存储技术的不断深入发展与广泛应用,网络集群服务与主机多路径技术成为信息系统容灾与安全解决方案中的两种重要核心技术。本研究课题将利用微软MPIO多路径框架将这两者进行整合,即在网络集群服务环境下研究MPIO主机多路径及其相关应用,进而从系统服务器与物理传输路径两个方面进行系统容灾与故障处理的分析研究。论文对基于Hyper-V和WSFC集群的主机多路径网络存储架构整合方案进行了研究；然后,对MPIO的核心部件—DSM设备子系统进行了详细的分析、设计与开发,其主要任务包括：智能选择最优路径、磁盘设备管理、网络集群服务以及I/O错误和异常处理。论文首先对课题研究的背景、现状及相关理论进行了阐述；然后在第三章对网络集群环境下的MPIO多路径进行了分析与研究,主要包括MPIO框架及其功能分析、网络集群服务与主机多路径的整合方案研究；论文的第四章主要对MPIO框架的DSM设备子系统进行了分析与设计,包括基于MPIO框架的DSM设备子系统分析以及各模块的架构设计,其中,在智能选路模块中,提出并设计了一种智能选择选路算法的策略,进而解决了手动设置选路算法的盲目性问题,在设备相关与错误和异常处理模块中,解决了MPIO的“假路径”问题；最后根据各个模块的详细设计对DSM设备子系统进行实现与验证分析,实验表明,DSM设备子系统能够正常工作,智能选择选路算法具有较好的I/O性能。
[Abstract]:With the continuous development and wide application of modern network storage technology, network cluster service and host multipath technology have become two important core technologies in information system disaster recovery and security solutions. This research will use Microsoft MPIO multipath framework to integrate the two, that is, in the network cluster service environment, we will study the MPIO host multipath and its related applications. Then the system disaster recovery and fault processing are analyzed and studied from two aspects of system server and physical transmission path. In this paper, the integration scheme of host multipath network storage architecture based on Hyper-V and WSFC cluster is studied, and then, a detailed analysis, design and development of the DSM device subsystem, the core component of MPIO, is given. Its main tasks include: intelligent selection of optimal paths, disk device management, network cluster services, and I / O error and exception handling. Firstly, the background, current situation and related theories of the research are described, and then in the third chapter, the MPIO multipath in the network cluster environment is analyzed and studied, including the MPIO framework and its function analysis. The fourth chapter analyzes and designs the DSM device subsystem of the MPIO framework, including the DSM device subsystem analysis based on the MPIO framework and the architecture design of each module. Among them, in the intelligent routing module, a strategy of intelligent routing algorithm is proposed and designed, which solves the blindness problem of manually setting routing algorithm. In the module of device correlation and error and exception handling, Finally, according to the detailed design of each module, the implementation and verification analysis of the DSM equipment subsystem are carried out. The experiments show that the DSM device subsystem can work normally, and the intelligent routing algorithm has better I / O performance.
