摘要： There is provided a data migrating method including the steps of: calculating, in a case where data stored in a volume is migrated to another volume, a required period of time for migrating the data based on a size of data to be migrated and volume configuration information on the volume in which the migrated data is stored and the volume to which the data is to be migrated; determining a start time at which the data migration starts to generate a volume migration plan; setting a priority of the generated volume migration plan; prioritizing, in a case where a periods of time during which the generated volume migration plan is executed and a period of time during which an existing volume migration plan is executed are overlapped with each other, and changing the start time of at least one of those volume migration plans having a lower priority.

摘要： When a volume belonging to a first storage tier is relocated to a second storage tier, in the event that an empty volume satisfying capacity conditions is not present in the second storage tier, an empty volume satisfying the capacity conditions within volumes belonging to a third storage tier is virtually allocated to the second storage tier, a further virtual empty volume is formed, and the volume is virtually relocated to the further virtual empty volume.

摘要： In a system comprising a first storage system providing plural first logical volumes including real logical volume and a virtual logical volume with a host, a second storage system having a second logical volume, and a management computer, when the first storage system receives an access request to the virtual logical volume, it accesses a second logical volume associated with the virtual logical volume. In this system, when the management computer receives a request to guard one of the plural first logical volumes, it checks whether a target first logical volume of the request is a real logical volume or a virtual logical volume, in case of the virtual logical volume, generates and provides a possible at least one option to guard the virtual logical volume by considering a program for volume guard, which each of the first storage system and the second storage system has.

摘要： A management computer monitors an allocated capacity of a source virtual volume and an allocated capacity of a virtual pool having a storage area allocated to a destination virtual volume in a storage, judges whether the allocated capacity of the source virtual volume can be covered in the virtual pool or not, and informs the user of a result that data migration fails when the allocated capacity of the source virtual volume cannot be covered. When the allocated capacity of the source virtual volume cannot be covered, the management computer uses another storage area to increase the capacity of the virtual pool. Accordingly, when data migration is performed between the virtual volumes, capacities of physical areas allocated to the source virtual volume and the destination virtual volume can be grasped so that the data migration can be performed accurately between the source virtual volume and the destination virtual volume.

摘要： A fluid dynamic pressure bearing includes a shaft arranged along a central axis, an annular member fixed to the shaft, a sleeve, a lubricant, and a lubricating film. A stepped surface is provided on the outer circumferential surface of the shaft. The annular member preferably includes a lower surface extending radially with respect to the central axis and arranged to make contact with the stepped surface in the inner edge portion of the lower surface. The sleeve preferably includes an upper surface axially opposed to the lower surface of the annular member. The lubricant is provided between the shaft and the sleeve and between the annular member and the sleeve. The lubricating film is provided on the lower surface of the annular member at least over a region lying radially outwardly of the inner edge portion of the lower surface.
