    Abstract: An optical disk RAID set is described that essentially comprises a plurality of optical recording disks including at least one full capacity disk and a plurality of less than full capacity disks. The full capacity disk possessing a rated storage capacity set by an original manufacturer. The less than full capacity disks, which are generally considered reject disks, do not meet the rated storage capacity due to surface flaws or other manufacturing defects. The less than full capacity disks are reserved for user data. Parity is generated from the user data on the less than full capacity disks. The parity data is stored to the full capacity disk.

    Abstract: Apparatus and associated method contemplating sending a bulk request to a first archive storage controller to transfer application data from a server at a target transfer rate, the first archive storage controller residing within a complex of archive storage controllers; identifying two or more archive storage controllers in the complex collectively forming a speed matching buffer set capable of parallel streaming the application data at a data transfer rate that is at least the target transfer rate; and as a result of the identifying step, apportioning the application data to the speed matching buffer set.

    Abstract: A magazine-based data storage library is described that essentially provides a first tape cartridge adapted to retain first data and first metadata, a second tape cartridge adapted to retain second data and second metadata, a random access storage memory, such as a hard disk drive, whereon parity of the first data and the second data along with the first metadata and second metadata is retained. It is not required that the first data and the second data be written in parallel. The parity data on the random access storage memory is transferred to a parity tape, which can be used to reconstruct any data lost from either the first tape cartridge or the second tape cartridge.

    Abstract: Apparatus and associated method contemplating: operating a storage server having access to a plurality of storage devices, at least a first storage device of the plurality of storage devices defining a first bank and at least a second storage device of the plurality of storage devices defining a second bank; during a first time interval, energizing the first bank to enable data transfer, and de-energizing the second bank to disable data transfer; during the first time interval, mapping data received from the storage server to the first bank; during a second time interval that begins before a storage capacity of the first bank is full, de-energizing the first bank to disable data transfer, and energizing the second bank to enable data transfer; and during the second time interval, mapping the data received from the storage server to the second bank.
