Abstract

The data striping technique has been successfully applied on disks to reduce the time to access objects from the disks as shown in Chapter VI. Similarly, the striping technique has been investigated to reduce the time to access objects from the tape libraries. Similar to the striping on disks, the objective of the parallel striping method is to reduce the time to access objects from the tape libraries. The parallel tape striping directly applies the striping technique to place data stripes on tapes. The triangular placement method changes the order in which data stripes are stored on tapes to further enhance the performance. In the next section, the parallel tape striping method will be described. The performance of the parallel tape striping follows. After that, the triangular placement method is explained, and it is followed by the performance of the triangular placement method.
