    摘要: Various embodiments for storing a logical object are provided. In one such embodiment, by way of example only, incoming data is divided corresponding to a logical data object into a plurality of independent streams, associating each data chunk of a plurality of obtained data chunks with a corresponding stream among the plurality of independent streams. At least one of the obtained data chunks and derivatives thereof is sequentially accommodated in accordance with an order the obtained chunks are received, while keeping the association with the corresponding streams. A global index is generated as a single meta-data stream accommodated in the logical data object and comprising information common to the plurality of independent streams and related to mapping between data in the logical data object and the obtained data chunks.

    摘要: Systems capable of transformation of logical data objects for storage and methods of operating thereof are provided. One method includes identifying among a plurality of requests addressed to the storage device two or more “write” requests addressed to the same logical data object, deriving data chunks corresponding to identified “write” requests and transforming the derived data chunks, grouping the transformed data chunks in accordance with the order the requests have been received and in accordance with a predefined criteria, generating a grouped “write” request to the storage device, and providing mapping in a manner facilitating one-to-one relationship between the data in the obtained data chunks and the data to be read from the transformed logical object. The method further includes obtaining an acknowledging response from the storage device, multiplying the obtained acknowledging response, and sending respective acknowledgements to each source that initiated each respective “write” request.

    摘要: For on-line separation of data chunks for compression, unrelated data chunks are classified based on various attributes. The classified data chunks are sent to at least one available compression contexts. The classified data chunks are related. The classified data chunks are encoded by at least one the compression operations. A compression ratio is achieved and included as feedback.

    摘要: For efficiently storing and retrieving data and metadata in phases, in a first phase, metadata tokens, which are assigned to most active metadata-emitting entities, are used for storing the data and the metadata together in a single input/output operation while piggybacking the metadata of least active metadata-emitting entities onto one of the most active metadata-emitting entities having one of the metadata tokens. In a second phase, the metadata is re-written to a metadata delta journal for reclaiming the metadata tokens. In a third phase, the metadata journal is applied to a metadata structure containing the metadata of the storage system, the metadata delta journal is then cleared after successfully updating the main metadata structure with the metadata of the metadata journal. The metadata journal is swapped with an empty metadata journal for concurrently adding metadata while retaining the metadata journal until applying the metadata delta journal to the metadata structure.

    摘要: A compression system configured to compress logical data objects into one or more accommodation blocks with a predefined size, and a method of operating thereof are provided. The compression system includes a compression engine capable of compressing input data with the help of sequential encoding one or more input strings and a counter operatively coupled to the compression engine. The counter is configured to keep its ongoing value indicative of a number of input bytes in one or more strings successfully encoded into a given accommodation block; and, responsive to unsuccessful compression of a string into the given accommodation block, to provide the compression engine with information indicative of starting point in the input stream for encoding into the next accommodation block, thus giving rise to a “start indication.”

    摘要: Various embodiments for transforming a logical data object for storage in a storage device operable with at least one storage protocol are provided. In one such embodiment, the logical data object into one or more segments are divided with each segment characterized by respective start and end offsets. One or more obtained variable size data chunks are processed corresponding to the logical data object to obtain processed data chunks, wherein at least one of the processed data chunks comprises transformed data resulting from the processing. Each of the variable size data chunks is associated with a respective segment of the logical data object. The processed data chunks are sequentially accommodated in accordance with an order of chunks received while keeping the association with the respective segments
