摘要： A tape cartridge for retaining a magnetic tape, the tape cartridge being configured to be selectively positioned substantially within a tape drive, includes a cartridge body and a cartridge hub. The cartridge body includes a cartridge length from a front to a rear of the cartridge body, and a cartridge width from a first side to a second side of the cartridge body. The cartridge hub is positioned within the cartridge body. The cartridge hub is configured so that the magnetic tape is wound around the cartridge hub within the cartridge body. The cartridge hub includes a hub diameter. The cartridge length and the cartridge width provide boundaries for a maximum wound tape diameter as the magnetic tape is wound around the cartridge hub within the cartridge body. A ratio of the maximum wound tape diameter to the hub diameter is at least approximately 3.50:1.

摘要： A magnetic tape device or system can store erasure encoded data that generates a multi-dimensional erasure code corresponding to an erasure encoded object comprising a code-word (CW). The multi-dimensional erasure code enables using a single magnetic tape in response to a random object/file request, and correct for an error within the single magnetic tape without using other tapes. Encoding logic can further utilize other magnetic tapes to generate additional parity tapes that recover data from an error of the single magnetic tape in response to the error satisfying a threshold severity for a reconstruction of the erasure coded object or chunk(s) of the CW. The encoding logic can be controlled, at least in part, by one or more iterative coding processes between multiple erasure code dimensions that are orthogonal to one another.

摘要： The technology disclosed herein enables automatic implementation of a physical barrier to protect access to data on removable storage media. In a particular embodiment, a method provides determining that the item moved into a storage position using an automatic transfer mechanism and determining that a condition for protecting the item is satisfied. Upon determining that the condition is satisfied, the method provides implementing a physical barrier that prevents the automatic transfer mechanism from removing the item from the storage position.

One example apparatus includes a first chunking circuit that generates a set of data chunks from a message, an outer precoding circuit that generates a set of precoded data chunks and a set of parity symbols from the set of data chunks, a second chunking circuit that generates a set of chunked parity symbols from the set of parity symbols, a deduplication circuit that generates a set of deduplicated data chunks by deduplicating the set of precoded chunks or the set of chunked parity symbols, an unequal error protection (UEP) circuit that generates an encoded message from the set of deduplicated data chunks, and a storage circuit that controls the data storage system to store the set of deduplicated data chunks, the set of parity symbols, or the encoded message.

摘要： A tape layout module for determining a tape layout allocation strategy for laying out data on tape, the data being organized into a plurality of fixed-size subdata sets with each of the plurality of subdata sets including a plurality of codeword interleaves, the tape including a plurality of media defect characteristics, includes a tape layout optimization system including a processor that receives information on the plurality of media defect characteristics. The tape layout optimization system determines the tape layout allocation strategy based at least in part on at least one of the plurality of media defect characteristics. Additionally, the tape layout optimization system can determine the tape layout allocation strategy further based on distance spectra between pairs of the plurality of codeword interleaves. Further, the tape layout optimization system can determine the tape layout allocation strategy by selectively utilizing at least one tape layout parameter.

摘要： Methods and apparatus associated with data cold storage are described. Example apparatus include an array of data storage devices arranged in rows and columns. Columns of the array are orthogonal to rows. A row has an associated row-centric power supply, and a column has an associated column-centric local electronics module (LEM) that controls a data storage device in the column independently of other data storage devices in the array. Example apparatus include logics that control a power mode of a data storage device independently of other data storage devices in the array, that control a power mode of an LEM, that adaptively regulate the level of data stored in a buffer, and that determine whether a data object will be stored in the buffer or stored on a data storage device in the array, based on the probability the data object will be accessed within a threshold period of time.

摘要： Methods and apparatus associated with storing data in high or low energy zones are described. Example apparatus include a data storage system (DSS) that protects a message using an erasure code (EC). A location in the DSS may have an energy efficiency rating or a latency. Example apparatus include circuits that produce EC encoded data that has a likelihood of use, that select a location to store the EC encoded data in the DSS based on the energy efficiency rating, the latency, or the likelihood of use, that store the EC encoded data in the location, and that compute an order of retrieval for EC encoded data stored in the location. The order of retrieval may be based on the energy efficiency rating or the latency. The EC encoded data may also have a priority based on the number of erasures for which the EC corrects.

摘要： Methods, apparatus, and other embodiments associated with doubly distributing erasure encoded data in a data storage system are described. One example apparatus includes a set of data storage devices and a set of logics that includes an encoding logic that generates an erasure encoded object that includes code-words, and chunks the code-words into code-word chunks, and a distribution logic that interleaves members of the set of code-word chunks into a plurality of records, and distributes the records across the data storage devices and within individual data storage devices. Example apparatus may include a read logic that reads the plurality of stored records from the data storage devices, and ignores read errors, and a repair logic that monitors the set of data storage devices, replaces or repairs failing data storage devices, generates replacement records, and stores the replacement records on a replacement data storage device.
