| 20080313371 | METHOD AND SYSTEM FOR COMPRESSION OF DATA FOR BLOCK MODE ACCESS STORAGE - For use in a storage network comprising a plurality of network elements and operable with a block mode access storage protocol, a method of operating a compression system operatively coupled to at least one computer and to one or more storage devices configured as at least one storage logical unit accommodating data compressed by the compression system, the computer, the storage devices and the compression system are configured as separate network elements. According to the method, the compression system is configured to hold a virtual logical unit, the virtual logical unit is configured to virtually represent in non-compressed form the compressed data stored in the at least one storage logical unit. The size of the virtual logical unit corresponds to an estimated size of raw data which, being compressed, would substantially amount to a size of the storage logical unit. The method includes intercepting one or more data access-related requests from the at least one computer addressed to said storage logical unit, addressing the requests to the virtual logical unit, and facilitating mapping between the compressed data and their virtual representation at the virtual logical unit. | 12-18-2008 |
| 20090307249 | METHOD AND SYSTEM FOR TRANSFORMATION OF LOGICAL DATA OBJECTS FOR STORAGE - A method and system for transforming a logical data object for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimization and restoring thereof. Transforming the logical data object comprises creating in the storage device a transformed logical data object comprising a header and one or more allocated accommodation sections with predefined size; processing one or more sequentially obtained chunks corresponding to the transforming logical data object thus giving rise to the processed data chunks, wherein at least one of said processed data chunks comprises transformed data resulting from said processing; sequentially accommodating the processed data chunks into said accommodation sections in accordance with an order the chunks received, and generating at least one index section constituting a part of the transformed logical data object, said index section comprising one or more entries containing indicators to physical storage location of respective accommodation sections and, with respect to each processed data chunk, one or more records related to said chunk, wherein said records indicate offset and length of data in the logical data object to be read from the respective processed data chunk, and are associated with a time stamp indicating time of creating said record. The method further facilitates reading a data range from the transformed logical object in response to a read request specifying desired point in time to be read. | 12-10-2009 |
| 20090307250 | METHOD AND SYSTEM FOR TRANSFORMATION OF LOGICAL DATA OBJECTS FOR STORAGE - A method and system for transforming a logical data object for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimization and restoring thereof. Transforming the logical data object comprises creating in the storage device a transformed logical data object comprising a header and one or more allocated accommodation sections with predefined size; transforming one or more sequentially obtained chunks of obtained data corresponding to the transforming logical data object thus giving rise to the transformed data chunks; and sequentially accommodating the processed data chunks into said accommodation sections in accordance with an order said chunks received, wherein said accommodation sections serve as atomic elements of transformation/de-transformation operations during input/output transactions on the logical data object. The processing may comprise two or more data transformation techniques coordinated in time, concurrently executing autonomous sets of instructions, and provided in a manner facilitating preserving the sequence of processing and accommodating the processed data chunks. | 12-10-2009 |
| 20090327751 | METHOD AND SYSTEM FOR TRANSFORMATION OF LOGICAL DATA OBJECTS FOR STORAGE - A method and system for encrypting a plaintext logical data object for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimization and restoring thereof. Encrypting the plaintext logical data object comprises creating in the storage device an encrypted logical data object comprising a header and one or more allocated encrypted sections with predefined size; encrypting one or more sequentially obtained chunks of plaintext data corresponding to the plaintext logical data object thus giving rise to the encrypted data chunks; and sequentially accommodating the processed data chunks into said encrypted sections in accordance with an order said chunks received, wherein said encrypted sections serve as atomic elements of encryption/decryption operations during input/output transactions on the logical data object. | 12-31-2009 |
| 20100017423 | METHOD AND SYSTEM FOR TRANSFORMATION OF LOGICAL DATA OBJECTS FOR STORAGE - A method and system for transforming a logical data object for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimization and restoring thereof. Transforming the logical data object comprises creating in the storage device a transformed logical data object comprising a header and one or more allocated accommodation sections with predefined size; sequentially obtaining one or more data chunks corresponding to the transforming logical data object; verifying if obtained data chunks match certain criterion and processing the chunks in accordance with verification results thus giving rise to the processed data chunks, wherein, resulting from said processing, a processed data chunk holds transformed data if the criterion is matched and holds non-transformed data if the criterion is not matches; sequentially accommodating the processed data chunks into said accommodation sections in accordance with an order said chunks received, and facilitating mapping between the data in the logical data object and the data accommodated in the accommodation sections. | 01-21-2010 |
