摘要： A method and apparatus is disclosed in which a storage controller cooperable with a host and a plurality of controlled storage is provided to localize an impact of a failure to a target disk in an affected segment. The storage controller includes a host write component to write a data object to a source image storage; a first copy component responsive to a first metadata state to control copying of the data object to a first target storage; a second copy component responsive to a second metadata state to perform either: copying the data object to a second target or causing the first copy component to copy the second target to the first target; and a third copy component to control cascaded copying of the data object to a third target storage. Either the second or the third copy component controls cascaded copying of a delimited data image subsequence responsive to a metadata state indicating currency of a data grain in either the second or the third target.

摘要： A mechanism is provided in a computing system for controlling virtualized storage operable to communicate with a host and with mapped and unmapped storage resource pools. A selection component selects a target for a destructive data storage operation from the mapped storage resource pool. Responsive to the selection of the target, a virtual targeting component creates a virtual target from the unmapped storage resource pool to represent the target. Responsive to the selection of the target, a storage move component moves the target to a protected storage resource pool. Responsive to the creation of the virtual target from the unmapped storage resource pool, storage move component, moves the virtual target to the used storage resource pool. The computing system then performs the destructive data storage operation on the virtual target.

摘要： The present invention provides for a method, system, and computer program product for managing the storage of data. Data is selectively compressed based on a pre-defined compression policy and metadata is stored for physical storage blocks. A stored compression policy identifies at least one criterion for compression, and physical blocks of data meeting the compression policy are identified. A physical block is selected as a source block for data compression, and one or more physical locations are selected as target locations. Data is read from the source block, compressed, and written to the target locations. Metadata is updated to indicate a mapping between the target locations and the virtual blocks previously mapped to the source block. Extra storage capacity can be freed up until more physical storage is ordered and installed, while more important data, such as recently or frequently accessed data, is retained in an uncompressed and accessible state.

摘要： The present invention relates to methods of copying and updating data in a processor memory during program run-time without suspending the program's access to its data in the memory during the data-copying and updating processes. In one aspect, the invention concerns a method of copying data from processor memory to a dump memory during run-time, including determining whether data in a segment of the processor memory is to be updated by a program and copying the data to a corresponding segment in the dump memory prior to the data being updated. According to one embodiment, a data-copying instance is utilized to obtain a point-in-time image of a data content of processor memory while the program is running.
