Abstract

Video server needs a storage system with large bandwidth in order to provide concurrently more users with the real time retrieval requests for video streams. So, the storage system generally has the structure of disk array, which consists of multiple disks. When the storage system serves multiple video stream requests, it's bottlenecks come from the seeking delay caused by the random movement of disk head and from unbalanced disk access due to disk load unbalance among multiple disks. This paper presents a novel placement and retrieval policy. The new policyretrieves the requested data through sequential movement of disk heads andmaintaining disk load balance so that it can diminish the bottlenecks on retrieving and can provide the concurrent real time retrieval services for more users simultaneously. In addition, the novel policy reduces the startuplatency for the requests. The correctness of the novel placement and retrieval policy is analyzed with theoretical views. Performance analysis of thenovel placement and retrieval policy is provided with simulations.
