摘　　要：服务器故障修复是确保服务器正常稳定运行的关键,为提升服务器可用性,保证服务器故障得到及时、有效修复,引入虚拟化组态软件应用程序,设计一种服务器冗余故障自修复方法。构建服务器冗余故障识别算法,分别识别出由不同赋值引发的两种故障集,完成冗余故障集识别;根据服务器的属性与特点,利用即时性数据库模块、输入输出设备驱动模块等硬件部分,组建虚拟化组态软件;对初始文件均分、聚类,采用极大距离可分码编码处理各聚类中的数据块,经迭代存储获取周期循环码编码结构,依据节点数量奇偶取值情况,挖掘自修复编码规则,结合发生冗余故障时的节点位置状况,制定不同的故障自修复流程。仿真结果表明,所提方法能够满足自修复的时效性与可行性,且优势显著。This paper designs a server redundancy fault self-repair method based on the virtualization configuration software for improving the availability and effective repair of the server. The server redundant fault identification algorithm was founded to identify the two fault sets caused by different assignments, achieving the redundant fault set identification. According to the attributes and characteristics of the server, the virtual configuration software was established by using the hardware parts such as the real-time database module and the input/output device driver module. Meanwhile, the maximum distance separable code was applied to encode the data blocks in each cluster, and the coding structure of periodic cyclic code was obtained through iterative storage. Based on the odd and even values of the number of nodes, the self-healing coding rules were mined. Different fault self-healing processes were designed according to the node location when redundant faults occur. The simulation results show that this method has timeliness and feasibility.
