    摘要： Provided is a method, system, and an article of manufacture for maintaining data accessible by a host in two storage devices, wherein the data is comprised of a plurality of data sets. A determination is made of a percentage of uncopied data at the first storage device, wherein uncopied data comprises data sets to be copied from the first storage device to the second storage device. If the calculated percentage is greater than a threshold amount, a rate at which uncopied data sets are transferred from the first storage device to the second storage device is increased.

    摘要： Disclosed is a system, method, and an article of manufacture for preferentially keeping an uncopied data set in one of two storage devices in a peer-to-peer environment when data needs to be removed from the storage devices. Each time a data set is modified or newly created, flags are used to denote whether the data set needs to be copied from one storage device to the other. The preferred embodiments modify the timestamp for each uncopied data set by adding a period of time, and thus give preference to the uncopied data set when the data from the storage device is removed based on the least recently used as denoted by timestamp of each data set. Once the data set is copied, the timestamp is set back to normal by subtracting the same period of time added on when the data set was flagged as needing to be copied.

    摘要： A data storage system provides a method and apparatus for preserving consistency between a database back-up and a set of storage volumes. The system includes a storage manager, or storage controller, interconnected to a plurality of storage volumes, a drive, and a database storage. The storage manager receives data files from an attached data processing unit. The storage manager directs the data files such that the files are written to a selected storage volume loaded into the drive. The storage manager maintains reference information and storage volume location information for each data file in the database storage. The storage manager detects a volume full condition when the storage media approaches a predetermined position prior to the physical end of the volume. The storage manager generates a back-up copy of the current database, transfers the database back-up to the drive, and directs the drive to write the database back-up onto the selected storage volume. Thus, each selected storage volume contains a database back-up which remains consistent with the data files currently stored on the selected storage volume and previously stored on previously selected storage volumes.

    摘要： Upgrades are made to the available capacity of cache disk storage without adding drawer(s) or blade(s) when the upgrade is requested. A cache control is configured to respond to a requested capacity upgrade, establishing a capacity restriction applicable to a filesystem providing active perceived available capacity spanning the disk drive subunits, such as drawers, blades or disk drives. The active perceived available data storage capacity and unused capacity of the filesystem are spread across the disk drive subunits. The capacity restriction is related to the requested upgrade adjustment, and the capacity restriction controls rates of data transfer with respect to the filesystem. The capacity restriction may comprise a freespace threshold for throttling of a fill rate of resident data pending premigration from the cache disk storage filesystem, and a premigration threshold for increasing drain rate of premigration data from the cache disk storage filesystem.

    摘要： Provided are a method, system, and program for managing data in storage units. Storage pool information indicates an assignment of a plurality of storage units to a plurality of storage pools, wherein each pool is assigned zero or more storage units, wherein data associated with one storage pool is stored in a storage unit assigned to the storage pool, wherein the storage pool information for each pool indicates a threshold and target storage pool, and wherein the target storage pool is capable of being different from the storage pool. One storage unit associated with a source storage pool is selected and a determination is made of the threshold from the storage pool information for the source storage pool. A determination is made of whether the selected storage unit satisfies the determined threshold and if the selected storage unit satisfies the determined threshold, then a target storage unit in the target storage pool is selected if the storage pool information for the source storage pool indicates a target storage pool different from the source storage pool. Data from the selected storage unit is copied to the selected target storage unit.
