摘要： A method and a system for implementing the method are disclosed relating to archival storage of information in large numbers of disk units. The reliability of the stored information is checked periodically using data verification operations whose results are saved. These results establish the veracity of the data and enable compliance with various regulatory requirements. The techniques described enable the use of low cost disk drive technology, yet provide high assurance of data veracity. In a typical system, management information storage is provided in which data entries are associated with each of the disk drives to provide information with respect to the condition of the data on that drive and its last verification. The data verification operations are performed on the data during time periods when I/O accesses are not required.

摘要： 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.

摘要： 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.

摘要： 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.
