Patent ID: 8117386

Claim:
A method of managing a performance history in a system including at least one storage device and a management server for managing the storage device, wherein data stored in a volume of the storage device is transferred to another volume for a data rearrangement, the method comprising the steps of: acquiring performance information of the volume of the storage device and managing by registering the performance information in a memory unit as time-series storage performance history information; acquiring, from the storage device, data rearrangement history information providing a history of data transfer between volumes of the storage device for the data rearrangement; and managing, by registering in a memory unit, a performance history of a transferer volume of predetermined data and a performance history of a transferee volume in correspondence with each other, based on the storage performance history information and the data rearrangement history information, wherein data is transferred from the transferer volume to the transferee volume for the data rearrangement; and generating data-oriented performance history, based on the performance history of the transferer volume and the performance history of the transferee volume, wherein the data-oriented performance history is generated in correspondence with a life cycle of the predetermined data, the life cycle including a new assignment of the volume of the storage device, the transfer of the predetermined data stored in the volume to another volume, and the period before cancellation of an assignment of the transferee volume, for management of the performance history of the predetermined data.
