Claim One:
1. A resource management method targeting multiple instances having a logical server, the method comprising: retaining one or more performance patterns that include a characteristic quantity extracted from a performance information of the resource in association with a bottleneck factor; detecting deterioration of performance of one or more resources assigned to a first instance, where the one or more resources include a first virtual volume associated with the first instance; extracting the first instance sharing a particular resource exhibiting the performance deterioration; calculating a mutual similarity by comparing a performance tendency showing properties and characteristics of performance of the first instance and each of the one or more performance patterns; estimating a bottleneck factor for a particular performance pattern from the one or more performance patterns having a maximum mutual similarity; selecting an optimal candidate configuration from a plurality of potential configuration candidates based on the bottleneck factor, wherein each of the plurality of potential configuration candidates includes one or more candidate resources, and the one or more candidate resources include a second virtual volume; and automatically migrating the first virtual volume to the second virtual volume based on the optimal candidate configuration, wherein: one of the performance patterns is a characteristics of timing in which a threshold for determining deterioration of performance of the resource is exceeded in time series; and the similarity is calculated based on a correlation between one of the performance patterns and a time-series fluctuation of performance of at least one of the one or more resources of the first instance.
