    摘要: A method executable on one or more processors for modeling a test space is provided. The method may include defining a coverage model including a set of variables. The method may also include selecting one or more variables within at least one subset of a plurality of subsets of the set of variables. The selection may be according to an interaction level requirement defined for at least one or more of the subsets, whereby the interaction level corresponds to a coverage of the test space that covers a plurality of possible combinations of the one or more variables at multiple levels. Furthermore, respective values for the one or more selected variables within the subset of the set of variables may be assigned. The method may also include one or more definitions for value combinations for said variables with assigned values.

    摘要: A computer implemented method is disclosed for obtaining file-level information from block level information of files stored on a storage medium. The method includes accessing the storage medium to obtain metadata available in block level on the storage medium and building an inverse block-to-file map of the files stored on the storage medium. The method also includes listening online to incoming block-level commands communicated from a host to the storage medium, parsing the incoming block-level commands, inferring file-level information from the parsed block level commands; and updating the inverse file-level map. Also disclosed are corresponding computer program product and processing system.

    摘要: A novel and useful method of implementing a full coverage low power mode in a storage system comprised of one or more memory storage devices storing replicated data items. A subset of the memory storage devices is chosen whose replicated data items require the least amount of storage. If the chosen subset stores uncovered data items, these data items are copied to an auxiliary memory storage device. The storage system can enter a full coverage low power mode by powering down the chosen subset of memory storage devices.
