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： A method for migrating data between heterogeneous data storage devices within a storage area network is disclosed. A first virtualizer presents stored data as a first virtual disk, and then communicates a managed disk representation of the first virtual disk to a second virtualizer. After receiving the managed disk representation, the second virtualizer virtualizes the stored data from the managed disk representation as a second virtual disk. At such point, the stored data can be progressively migrated from the first virtualizer to the second virtualizer.
