Abstract
In an embodiment, a storage system includes pools each of which includes storage resources and is separated into tiers different in access performance. A management system monitors access performance of the pools to detect a risky pool expected to become unable to satisfy predetermined access performance requirements. The management system estimates access performance of each of one or more candidate pools in the pools in the case where a storage resource migrates from the candidate pool to the risky pool, by simulation based on variations in data arrangement in the pool caused by evacuating data held in the storage resource in the same pool for the migration of the storage resource. The management system determines that a storage resource migrates from a source pool of which the estimated access performance satisfies predetermined performance requirements to the risky pool.
