Fault isolation and recovery method for eight-path rack-mounted server

The invention discloses a fault isolation and recovery method for an eight-path rack-mounted server. The fault isolation is divided into physical fault isolation, control information isolation and data isolation. The fault isolation recovery method comprises the following steps: step 1, constructing a five-dimensional fault isolation recovery model; step 2, constructing evaluation indexes; step 3, normalizing the time indexes; 4, establishing a recovery capability evaluation model; and 5, judging a recovery condition according to an evaluation result. According to the method, an operation and maintenance object recovery evaluation model including a host, a system, a network, a database, middleware and the like is constructed, an intelligent five-dimensional model is formed, multiple dimensions of services, transactions, topologies, physical links and infrastructures are covered, services and software and hardware resources are throughout, guarantee key points and fault recovery capability of a data center are
