    摘要： Exemplary method, system, and computer program product embodiments for real-time selection of compression operations are provided. In one embodiment, by way of example only, available compression operations are initialized according to an assigned success factor. The available compression operations are tested for determining if at least one of the compression operations yields a compression ratio greater than a minimal compression ratio. The available compression operations selected in real time for compressing at least one of the data blocks is applied. Additional system and computer program product embodiments are disclosed and provide related advantages.

    摘要： There are provided a method of transforming a non-transformed stored logical data object (LO) device into a transformed LO and system thereof. The method comprises: a) in response to a respective transformation request, logically dividing the non-transformed LO in a first segment and one or more non-transformed subsequent segments, the segments having predefined size; b) generating a header for the respective transformed LO; c) processing said first segment; d) overwriting said first segment by said generated header and said transformed first segment; e) indexing said first transformed segment and said one or more non-transformed subsequent segments as constituting a part of said transformed LO; f) generating at least one index section; and g) updating the indication in the header to point that the non-transformed LO has been transformed in the transformed LO comprising said generated header, said first transformed segment, said one or more subsequent segments comprising data in non-transformed form and said at least one index section.

    摘要： In a storage system, using a pool of encryption processing cores, the encryption processing cores are assigned to process either encryption operations, decryption operations, and decryption and encryption operations, that are scheduled for processing. A maximum number of the encryption processing cores are set for processing only the decryption operations, thereby lowering a decryption latency. A minimal number of the encryption processing cores are allocated for processing the encryption operations, thereby increasing encryption latency. Upon reaching a throughput limit for the encryption operations that causes the minimal number of the plurality of encryption processing cores to reach a busy status, the minimal number of the plurality of encryption processing cores for processing the encryption operations is increased.
