摘要： Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data are provided. Undeduplicated data is stored with a first cyclic redundancy check (CRC) seed. A stub pointing to the parent copy of the deduplicated data is stored with a second CRC seed. Subsequent to reading the deduplicated data, the first CRC seed is associated with the undeduplicated data, and the second CRC seed is associated with the stub. A CRC check is performed using one of the first and second CRC seeds. If the CRC check is positive, an I/O operation is allowed to proceed. If the CRC check is negative, an additional CRC check is performed using another one of the first and second CRC seeds.
摘要翻译：提供了用于区分指向重复数据删除数据的父副本的数据和存根之间的各种实施例。未经复制的数据与第一循环冗余校验（CRC）种子一起存储。指向重复数据删除数据的父副本的存根与第二个CRC种子一起存储。在读取重复数据删除的数据之后，第一个CRC种子与未被复制的数据相关联，第二个CRC种子与存根相关联。使用第一和第二CRC种子之一执行CRC校验。如果CRC校验为正，则允许进行I / O操作。如果CRC校验是否定的，则使用第一和第二CRC种子中的另一个来执行附加的CRC校验。

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： An apparatus, system, and method are disclosed for hard disk drive redundancy. A demarcation module demarks a parity data block in each set of a specified number of data blocks on a hard disk drive. An association module associates a PBA of each un-demarked data block with a LBA. A write module writes the data to the un-demarked data blocks. A parity module calculates parity data for the data written to the un-demarked data blocks and the write module writes the parity data to the parity data block.

The velocity calculator further employs a velocity estimating module for generating a higher-order current servo frame velocity signal indicative of a second or higher order velocity calculation of the current servo frame velocity including a higher-order current servo frame error term based on the first-order preceding servo frame velocity signal and the first-order current servo frame velocity signal.
