More Information
Summary:A method, system, apparatus and computer program product for determining an optimal file operational time in a data storage system for use with a tape media storing data in a serpentine pattern on tape media is provided. The operational time is optimized based on a "sequence on tape" algorithm, a "minimum reversal of direction on tape" algorithm, or a "minimum delay to next data" algorithm. A model is used to determine the predicted performance of each of the algorithms, and the algorithm that provides the minimum overall operational time is chosen and applied for carrying out an operational process on the tape media.
