AVAILABILITY EVALUATION DEVICE AND AVAILABILITY EVALUATION METHOD

摘要

Workload is mitigated when customizing adding a state transition resulting from a datacenter operation procedure, to an availability evaluation model of a server infrastructure, provided as a standard library. This involves: storing in a state transition storage unit (STSU) definitions of a plurality of state transitions corresponding to system configurations; storing in an additional STSU definitions of state transitions used in system operation, which are different from the plurality of state transitions; receiving definitions of state transitions and registering the definitions in the additional STSU; analyzing system availability based on the definitions of the state transitions stored in the STSU and the definitions of the state transitions stored in the additional STSU; analyzing common state transition patterns in at least part of definitions of the plurality of state transitions used when operating the system, and stored in the additional STSU; and outputting analysis results on the common state transition patterns.
