    • Provided is an access right managing method for a resource of a storage system, in which a management computer stores access right definition information of the resource, and resource correspondence information including information on a management program which manages another resource related to the resource managed by the management program. In case of which receiving an updating request of an access right of the resource, the management computer updates an access right based on the updating request of the access right, selects a management program of the resource whose access right is requested to be updated based on the resource correspondence information, transmits an updating request of an access right for a relative resource to a management computer which executes the selected management program, and in case of which the access right updating request of the related resource is received, updates the access right of the relative resource.

    • Groups of volumes having a certain amount of commonality of data are identified within a storage system. For each group, the process defines a base volume, such as the volume containing the most commonality with the other volumes. For each volume in the group, the process extracts differential data between the base volume and each other volume, saves the differential data in a pool volume, and updates a mapping table. Commonality between volumes in the group is managed in the base volume, the pool volume, and the mapping table. Then the original volumes except the base volume and the pool volume may be deleted, and the original volumes are replaced with virtual volumes accessible through the mapping table. As a result, the amount of data in a storage system can be reduced while maintaining data integrity and accessibility.
    • 在存储系统内识别具有一定数量的数据通用性的卷组。 对于每个组,该进程定义基本卷,例如与其他卷最相似的卷。 对于组中的每个卷,该进程提取基本卷和每个卷之间的差异数据,将差异数据保存在池卷中,并更新映射表。 组中的卷之间的通用性在基本卷,池卷和映射表中进行管理。 然后可以删除基本卷和池卷以外的原始卷,并将原始卷替换为可通过映射表访问的虚拟卷。 因此,可以在保持数据完整性和可访问性的同时减少存储系统中的数据量。

    • A method for operating a storage system includes providing a primary storage device and a secondary storage device. Data from a first storage volume is copied to a second storage volume using an internal mirror operation, the first and second storage volumes being provided within the primary storage device. The data received from the first volume is copied from the second storage volume to a third storage volume using a remote copy operation, the third storage volume being provided in the secondary storage device. The second storage volume is used for the remote copying to reduce the IO impact on the first volume. The third storage volume copies the data received from the second volume to a fourth storage volume using an internal mirror operation, the fourth storage volume being provided within the secondary storage device. The secondary storage system includes a fifth storage volume that is made available to a secondary host while the data from the third storage volume is being copied to the fourth storage volume, the secondary host being associated with the secondary storage device.
    • 一种用于操作存储系统的方法包括提供主存储设备和辅助存储设备。 使用内部镜像操作将来自第一存储卷的数据复制到第二存储卷,第一和第二存储卷被提供在主存储设备内。 使用远程复制操作将从第一卷接收到的数据从第二存储卷复制到第三存储卷,第三存储卷被提供在辅助存储设备中。 第二个存储卷用于远程复制,以减少对第一个卷的IO影响。 第三存储卷使用内部镜像操作将从第二卷接收到的数据复制到第四存储卷,在第二存储设备中提供第四存储卷。 辅助存储系统包括第五存储卷,其使第二存储卷可用于来自第三存储卷的数据被复制到第四存储卷,辅助主机与辅助存储设备相关联。

    • A virtualization system is introduced between a host and a storage system. An apparatus, system, and method of migrating replication includes stopping or making dormant applications on a host, or checking whether the applications are stopped or dormant. The statuses of a primary volume and a secondary volume that is a replica of the primary volume are checked to determine whether they have become identical. A primary virtual volume is defined to map to the primary volume and a secondary virtual volume is defined to map to the secondary volume. Replication is defined from the primary virtual volume to the secondary virtual volume. Replication is started with a NOCOPY option, and the applications may be restarted or a message is sent indicating that the applications can be restarted. There is no actual migration of application data, and as result, the time required for migrating replication can be eliminated.
    • 在主机和存储系统之间引入了虚拟化系统。 迁移复制的装置,系统和方法包括在主机上停止或使休眠应用程序,或检查应用程序是停止还是休眠。 检查作为主卷的副本的主卷和辅助卷的状态,以确定它们是否相同。 主虚拟卷被定义为映射到主卷,并且定义辅助虚拟卷以映射到辅助卷。 复制从主虚拟卷定义到辅助虚拟卷。 使用NOCOPY选项启动复制,并且可能会重新启动应用程序或发送指示可以重新启动应用程序的消息。 没有实际迁移应用程序数据,因此可以消除迁移复制所需的时间。
