摘要： An apparatus or method for operating a mirrored disk storage system, comprises a detector component operable to detect that a failure has left read stability in doubt, a determiner component for determining a repair characteristic of a pair of mirrored disks, a comparator for comparing the repair characteristic of a first of the pair with the repair characteristic of a second of the pair, and a selector for selecting one of the first or the second of the pair having a preferred repair characteristic to be used as a synchronization source disk. The preferred repair characteristic comprises the characteristic that no repair is required for the one of the first or the second of the pair, or that a least repair time is required for the one of the first or the second of the pair.

摘要： A targeting storage component selects a target virtual disk for one of a full copy or an incremental copy of first data. A periodic backup component triggers a periodic point-in-time copy of the first data to a virtual disk in the cascade. A testing component tests a status of the full copy, the incremental copy and the periodic point-in-time copy. Responsive to the status, a cascade splitting component splits the cascade to remove a dependency relationship of at least one of the fully copy, the incremental copy and the periodic point-in-time copy on the first data.

摘要： Provided are techniques for maintaining instant virtual copies. A request to perform an instant virtual copy operation to create an instant virtual copy from a first volume to a new volume is received. It is determined that the first volume has not been modified since a last instant virtual copy operation has been performed. It is determined whether an intermediate volume and an intermediate map have already been created. In response to determining that the intermediate volume and the intermediate map have not already been created, the intermediate volume and the intermediate map are created, the intermediate volume is made dependent on the first volume in a dependency chain based on the intermediate map, and the new volume is made dependent on the intermediate volume in the dependency chain.

摘要： A data storage system comprises a controller, a first lower performance storage medium and a second higher performance storage medium. The controller is connected to the storage mediums and is arranged to control Input/Output (IO) access to the storage mediums. In operation, the controller is arranged to store an image on the first storage medium, initiate a copy function from the first storage medium to the second storage medium, direct all IO access for the image to the second storage medium, and periodically age data from the second storage medium to the first storage medium.
