Abstract

Given the present cost of memories and the very large storage and bandwidth requirements of large-scale multimedia databases, hierarchical storage servers, consisting of RAM, disk storage, and robot-based tertiary libraries, are becoming increasingly popular. However, related research is scarce and employs tertiary storage for storage augmentation purposes only. This work, exploiting the ever-increasing performance offered by (particularly) modern tape library products, aims to utilize tertiary storage in order to augment the system's performance. We consider the issue of elevating continuous data from its permanent place in tertiary for display purposes. Our primary goals are to save on the secondary storage bandwidth that traditional techniques require for this process and require no additional RAM buffer space. To this end we develop algorithms where the playback is shared between the secondary and tertiary devices and for placing the blocks of continous objects on tapes, and show how our goals are met. We study these issues for products of different bandwidth and in environments with and without the multiplexing of tape libraries.
