    摘要： This invention intends to provide the computer system equalizing the storage capacity immediately and appropriately to multiple real logical areas dynamically providing storage capacity to virtual logical areas. This invention is the computer system which, in the process of performing the dynamic allocation of storage areas to virtual volumes in response to accesses from the higher-level device, when adding pool volumes to the pool, migrates storage areas among multiple logical areas, and maintains the balance of the storage capacity.

    摘要： The present invention comprises a virtual volume 50, which is a virtual storage area comprising multiple virtual page groups, a pool 60, which is a storage area comprising multiple pool page groups having different access performance, and a controller 13, which comprises a corresponding relationship between the virtual page and the pool page, and accesses the pool page corresponding to the virtual page based on accesses to the virtual page from other apparatuses, and the controller 13, based on an access load trend with respect to each virtual page in each time slot, executes processing for deciding an ideal pool page allocation destination for each virtual page in each time slot, and reallocating a virtual page to the ideal pool page at a time, which is prior to a start time, so that the ideal pool page can be allocated to each virtual page by the start time of each time slot.

    摘要： A storage system comprises a storage medium including a plurality of physical storage areas. The storage system controls a host computer to recognize a logical volume having a plurality of virtual storage areas, reads the data from the physical storage area assigned to the virtual storage area of the logical volume, determines whether or not the read data includes only the specific pattern data, and cancels the assignment of the physical storage area to the virtual storage area if the read data includes only the specific pattern data.

    摘要： A virtualization system, upon judging that a write operation from a higher-level device is an operation to write in the format of the virtual volume, even when the write position of the write operation is in a virtual area different from a virtual area to which an allocated actual area has been allocated, if there is an unused area in the allocated actual area, writes management information to the unused area according to the write operation, and if there is no unused area in the allocated actual area, newly allocates an unallocated actual area, and writes management information to the newly allocated actual area according to the write operation.

    摘要翻译： 虚拟化系统在判断来自较高级设备的写入操作是以虚拟卷的格式写入的操作时，即使当写入操作的写入位置在与虚拟区域不同的虚拟区域中时， 如果分配的实际区域中存在未使用区域，则根据写入操作将管理信息写入未使用区域，并且如果在所分配的实际区域中没有未使用区域，则新分配未分配的实际区域 实际区域，并根据写入操作将管理信息写入新分配的实际区域。
