摘要： The present invention achieves data relocation in accordance with a user's policies, in an environment where a plurality of storage devices coexist. The volumes belonging to storage devices A-D are managed virtually integrally. A host recognizes a plurality of storage devices A-D as a single virtual storage device. The user is able to group arbitrarily each volume belonging to the storage system, as a plurality of storage layers 1-3. For example, storage layer 1 can be defined as a high-reliability layer, storage layer 2, as a low-cost layer, and storage layer 3, as an archive layer. Each storage layer is constituted by a group of volumes corresponding to respective policies (high reliability, low cost, archiving). The user designates volumes V1 and V2 to be moved, in group units, and indicates a storage layer forming a movement destination, whereby the data is relocated.

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： In a computer system an object of this invention is to reduce physical resource contentions during the parallel migration of volumes. The computer system of this invention has the host computers, the storage systems and the storage management server. When parallelly migrating two or more volumes of data in the storage systems to the same number of other volumes, the storage management server selects volumes having few physical conflicts of the controllers or storage devices in the storage systems and executes the parallel migration operation.

摘要： In a fluid dynamic bearing apparatus, an oil buffer is defined between a thrust gap and a pumping gap. The oil buffer has an axial dimension greater than that of the thrust gap, and/or has a radial dimension greater than that of the pumping gap. An air bubble generated in the thrust gap due to cavitation, for example, when a fluid dynamic bearing apparatus experiences a vibration can be dissolved in lubricating oil provided within the oil buffer. This prevents leakage of the lubricating oil due to the air bubble residing in the fluid dynamic bearing apparatus.
摘要翻译：在流体动力轴承装置中，在推力间隙和泵送间隙之间限定油缓冲器。油缓冲器的轴向尺寸大于推力间隙的轴向尺寸，和/或具有大于泵送间隙的径向尺寸的径向尺寸。例如当流体动力轴承装置发生振动时，在推力间隙产生的推力间隙中产生的气泡可以溶解在设置在油缓冲器内的润滑油中。这样可以防止润滑油由于存在于流体动力轴承装置中的气泡而泄漏。
