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.
摘要翻译：提供了用于存储逻辑对象的各种实施例。在一个这样的实施例中，仅作为示例，将对应于逻辑数据对象的输入数据划分成多个独立流，将多个获得的数据块中的每个数据块与多个独立流中的对应流相关联。所获得的数据块及其派生中的至少一个按照所获取的块被接收的顺序顺序地被容纳，同时保持与相应流的关联。全局索引被生成为容纳在逻辑数据对象中的单个元数据流，并且包括与多个独立流共同的信息，并且涉及逻辑数据对象中的数据与获得的数据块之间的映射。

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 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.
摘要翻译：为了分阶段地有效地存储和检索数据和元数据，在第一阶段中，分配给最活跃的元数据发射实体的元数据令牌被用于将数据和元数据一起存储在单个输入/输出操作中，同时将最不活跃的元数据发射实体的元数据发送到具有元数据令牌之一的最活跃的元数据发射实体之一上。在第二阶段，将元数据重新写入到元数据增量杂志中以回收元数据令牌。在第三阶段，元数据日记应用于包含存储系统的元数据的元数据结构，然后在使用元数据日志的元数据成功更新主元数据结构之后，元数据增量日志将被清除。元数据日志与一个空的元数据日志交换，用于同时添加元数据，同时保留元数据日志，直到将元数据增量日志应用到元数据结构。

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
