摘要： A magnetic storage media includes a magnetic south-north servo band section and a magnetic north-south servo band section. The magnetic south-north servo band section includes a magnetic south-pole polarity initialized servo track segment and a magnetic north-pole polarity servo pattern recorded on the magnetic south-pole polarity initialized servo track segment. The magnetic north-south servo band section includes a magnetic north-pole polarity initialized servo track segment, and a magnetic south-pole polarity servo pattern recorded on the magnetic north-pole polarity initialized servo track segment. The magnetic south-north servo band section and the magnetic north-south servo band section are recorded relative to each other on a servo track to represent magnetic polarity encoded servo position information based on the magnetic north-pole polarity servo pattern and the magnetic south-pole polarity servo pattern.

摘要： A method for deduplicating and managing data blocks within a file system includes adding a deduplication identifier to each pointer pointing to a data block to indicate whether the data block is deduplicated, detecting duplicate data blocks, determining whether one of the duplicate data blocks has been deduplicated, when detected, determining that one duplicate data block is a master copy when it is determined that one duplicate data block has been deduplicated, selecting one of the duplicate data blocks to be a master copy when it is determined that the duplicate data blocks have not been deduplicated, and setting the deduplication identifier of the selected duplicate data block to indicate deduplication, and determining that the other duplicate data block is a new duplicate data block and setting the deduplication identifier of the other duplicate data block to indicate deduplication and directing the respective pointer to the master copy.

摘要： A Redundant Array of Independent Devices uses convolution encoding to provide redundancy of the striped data written to the devices. No parity is utilized in the convolution encoding process. Trellis decoding is used for both reading the data from the RAID and for rebuilding missing encoded data from one or more failed devices, based on a minimal, and preferably zero, Hamming distance for selecting the connected path through the trellis diagram.

摘要： A storage management application determines that a source virtual tape requires reclamation, identifies all block addresses for active data of a source virtual tape and sorts the block addresses in an ascending order, identifies a target virtual tape which has sufficient free capacity to store the active data of said source virtual tape and the last written block address on said target virtual tape, and sends a command to the VTL-system instructing it to perform reclamation including information about said source and said target virtual tape, the sorted list of block addresses denoting active data on the source virtual tape and the starting block address on the target virtual tape. The reclamation logic references the active data host blocks of said source volume to said target virtual tape starting at said starting block address by just updating the host block to disk block mapping table.
