Paper Abstract

Although emerging mass storage devices, including robotic tape libraries, optical jukeboxes, and redundant array of inexpensive disks (RAID) systems, enable large softcopy image archives, timely dissemination of any image from the archive is not possible with popular hierarchical storage techniques. Significant delays occur for images located on slower storage devices such as robotic tape libraries. We developed a prototype, predictor of requested imagery and migration engine (PRIME), to provide more timely dissemination. PRIME reduces analysts' wait time by predicting the image requests and migrating the most likely of these images from slower to faster archive devices before analysts make these requests. PRIME uses a fuzzy logic expert system both to make the prediction and to perform the migration. We describe the PRIME environment, including the prediction and migration issues, and a description of the prototype.
