A multi-level hierarchical storage system (HSS) is able to provide large storage capacityfor multimedia data at a more economical cost than disk only systems. The retrieval ofmultimedia objects from the tertiary storage however imposes substantial performanceconstraints. As many multimedia applications access objects sequentially following apredetermined order, we have designed a concurrent striping method that store coldobjects following this order on the media units. We have carried out simulations to studyits performance, and it is observed that this method can improve the system throughput,stream response time, and disk buffer usage.
