Patent ID: 8225041

Claim:
A method of managing a performance history in a system including at least one storage device, a storage virtualization device for setting a real volume providing a real area of the storage device, a virtual volume, the real volume and the virtual volume being in correspondence with each other, and a management server for managing the storage and the storage virtualization device, wherein data stored in the volume of the storage device is transferred to another volume for a data arrangement, 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 virtualization device, data rearrangement history information providing a history of data transfer between virtual volumes of the storage virtualization device for the data arrangement; acquiring, from the storage virtualization device, virtual volume management information providing information on a correspondence between the virtual volume of the storage virtualization device and the real volume stored in the storage; generating and registering in the memory unit the data rearrangement history information of the real volume indicated by the real volume based on the data rearrangement history information and the virtual volume management information; managing by registering in the 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 of the real volume, 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 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.
