    摘要: A data storage subsystem in a distributed storage system having a plurality of predictive failure analyzing data storage devices. The subsystem furthermore has a circuit that is responsive to a predicted failure indication by a data storage device in relation to predetermined rules stored in memory for deterministically initiating a preventive recovery either by a data recovery procedure in the data storage device or by a fault tolerance storage arrangement in the subsystem.

    摘要: A method and a system is provided for increasing reliability of data stored in storage segments by increasing redundancy data and by permitting user data to fit around defective locations in the storage segment. User data is compressed and reserved for a portion of a storage segment having a data size corresponding to an uncompressed size of the user data. The compressed user data is written to the reserved portion of the storage segment and a pad byte pattern is written to any remaining portion of the reserved portion of the storage segment. The remaining portion of the reserved portion of the storage segment is designated as unused.

    摘要: A multi-dimensional recording (MDR) system may include a group based coding circuit (GBCC) which can implement error correcting codes via outer codes. The GBCC can implement outer codes, including interleaving outer codes, in MDR systems where inner codewords include multiple memory groupings. The multiple memory groupings may be across different structural divisions within a data storage medium; or could be across multiple different data storage mediums.

    摘要: A unified debug system with multiple user-configurable trace volumes is disclosed, including embodiments as a system, a method, and a computer-readable medium. Embodiments of the present invention provide more robust and flexible solutions for introducing configurable trace volumes to firmware, allowing a user to specify firmware system configurations for trace buffers, trace frames, and trace volumes, and offer other advantages over the prior art. One embodiment of the present invention pertains to a system that includes a firmware component comprising firmware, and a firmware interface communicatively connected to the firmware component. The firmware includes a plurality of trace volumes for storing a plurality of trace entries. The trace volumes are user-configurable through the firmware interface. The plurality of trace volumes includes first, second and third trace volumes. The first trace volume includes storing at least some of the trace entries to a trace buffer in a first volatile memory component. The second trace volume includes storing at least some of the trace entries to one or more trace buffers in one or more trace frames in a second volatile memory component. The third trace volume includes storing at least some of the trace entries to one or more trace buffers in one or more trace frames in a non-volatile memory component.
