Patent ID: 8205014

Claim:
An information apparatus that generates a tuning plan for a configuration of a resource of a storage system, comprising: a configuration information acquiring unit that acquires configuration information of the resource of the storage system; a performance data acquiring unit that acquires performance data of a reference value exceeding resource being the resource having a utilization rate exceeding a preset reference value, and performance data of an analysis target resource, which is a different type of a resource from the reference value exceeding resource, being the resource having a certain relationship with the reference value exceeding resource; a correlation degree calculating unit that obtains a correlation degree between the reference value exceeding resource and the analysis target resources based on the performance data of the reference value exceeding resource and the performance data of the analysis target resources; and a tuning plan generating unit that selects a correlated analysis target resource by referring the correlation degree, the correlated analysis target resource is included in the analysis target resource and having correlation with the reference value exceeding resource, calculates a first average resource utilization rate of a first resource group including the selected correlated analysis target resource and a resource of a same type as the selected correlated analysis target resource accessed by the reference value exceeding resource, calculates a second average resource utilization rate of a second resource group including the selected correlated analysis target resource and a resource of a same type as the selected correlated analysis target resource configuring a fail over cluster with the selected correlated analysis target resource, calculate a third average resource utilization rate of a third resource group including the selected correlated analysis target resource and a resource of a same type as the selected correlated analysis target resource belonging to a same storage apparatus, and generates a tuning plan for the configuration of the resources of the storage system by adding a resource of a same type as the correlated analysis target resource, if the first average resource utilization rate exceeds a first threshold or the second average resource utilization rate exceeds a second threshold or the third average resource utilization rate exceeds a third threshold.
