摘要:
A magazine-based data storage library in connection with a disk drive-based archive storage system is described that essentially generates parity data for tape formatted data streams (stored to tape cartridges) that do not align by way of data blocks or file marks. Data streams intended for tape storage sent to tape cartridges are also sent to a disk drive storage system via an encoder where parity of the data streams can be generated. More specifically, the encoder digitally formats tape blocks and tape marks (as well as other tape formatted structure) in a digital stream of data that can be added to other encoded digital streams of data to generate parity. To reconstruct a specific tape cartridge from a tape set, the encoded data from each of the tapes in the tape set are subtracted from the parity data and the remaining encoded data is decoded and sent to a designated tape cartridge.

Provided is a system and method for a robotic storage system. The system includes at least a first and second portable data element and at least a first and second data read/write device, structured and arranged to read portable data storage elements. A repository is structured and arranged to store the first and second portable data storage elements. At least one robot is structured and arranged to move a selected data storage element between the repository and a selected data read/write device. The system includes a history of prior commands, each prior command executed by a prior path selected from a group of optional paths. A receiver is structured and arranged to receive a current command for the robotic storage system, and a director is structured and arranged to direct the robotic storage system based on the current command and the history. An associated method is also provided.

Apparatus and associated methodology contemplating a data storage system having a memory that includes a first addressable storage space and a second differently addressable storage space. A controller selectively accesses stored instructions that when executed transfer some user data sets with the first addressable storage space in accordance with a dense allocation of the first addressable storage space, and transfer other user data sets with the second addressable storage space in accordance with a sparse allocation of the second addressable storage space that allocates a predefined reserved storage capacity between adjacent stored non-sequential user data sets.

An apparatus and associated methodology for a data storage system having a data storage space operably transferring user data via input/output (I/O) commands between the data storage system and another device. The data storage space includes a first memory device operably storing location information for a selected user data set corresponding to one of the I/O commands. The first memory also operably stores a first amount of the selected user data set. The data storage space also includes a second memory device different than the first memory device and operably storing a different second amount of the selected user data set. The data storage system has a controller that interleaves an entirety of the selected user data set from the first and second memory devices during execution of another of the I/O commands.
