....[5, 6] Multimedia objects can either be staged or pipelined from tertiary storage devices. In the staging method, a stream waits for the entire object to be retrieved before it starts to display. In the pipelining methods, a stream starts to display after the first slice of data is retrieved [7 10]. Pipelining methods reduce stream response time of single stream for low end tertiary drives, but they cannot be applied to concurrent streams for high end drives. The traditional striping methods [11 16] the time slice scheduling [17] and multiple readout algorithm [4] may reduce the stream ....

....and its application in a video management system are discussed in Section 6. Finally, we give our concluding remarks in 4 Section 7. 2 Conventional Pipelining We first review the concept of pipelining, and summarize some analyses relevant to this paper. Interested readers are referred to [6, 7] for more detail. A video file is logically divided into a sequence of data segments (S 0 ; S 1 ; S n Gamma1 ; S n ) where the playback duration of S i Gamma1 must eclipse the time required to materialize (download) S i , 8i; 1 i n. After the first data segment, S 0 , has been ....

....[9] performance study was carried out on a robotic storage system. In [4, 5] a novel storage structure known as the staggered striping technique was proposed as an efficient way for the delivery of multiple video or audio objects with different bandwidth demands to multiple display stations. In [8], a hierarchical storage server was proposed to support a continuous display of audio and video objects for a personal computer. In [11] the authors proposed a cost model for data placement on storage devices. Finally, a prototype of a continuous media disk storage server was described in [12] ....

....be stored on tertiary storage. This follows immediately considering that typical annual requirements for hospital information systems have been found to approximate one half of a Terabyte; while the required storage for a single 100 minute MPEG encoded video is in the range of a few Gigabytes. [15, 10, 27]. 5 Thus, even in this case, the available bandwidth of the disk array becomes the key to overall system performance, justifying our focus on optimizing the disk array performance. In our system model each object is divided into blocks of S bits. The disk array receives access requests for ....

....The model we develop is simple and allows us to address many performance and design issues of a video server of such kind. Previous work on hierarchical storage systems has been on justifying its cost advantage [54, 53, 55] or studying the possible operational procedures and their performance [56, 57, 58, 59, 60]. Our work differs in addressing how the system parameters in a hierarchical storage system can be dimensioned so as to satisfy a certain user delay requirement. We have developed a simple model which can be used to solve many design issues related to a hierarchical storage system. This chapter is ....

.... in terms of hit probability, the no release policy performs the best, and the random replacement policy performs the worst (their hit probabilities differ by about 10 in their examples) A pipelining mechanism to stage video file from the tertiary level to the secondary level is discussed in [58, 59] as a means to reduce user s start up delay. In such a system, video files can be displayed while being staged onto the secondary level. Three data flow sequences are examined in terms of their buffer requirements, the disk space requirements, and the conditions for continuity: i) sequential data ....

....While Won and Srivastava, and Bianchi et al. study the replacement algorithms for a hierarchical storage system [30] 31] we focus more on parameter dimensioning than the operational procedures. The use of pipelining in video staging to reduce user s startup delay files has been discussed in [32], 33] 34] Their schemes, however, do not offer interactive capability to the users.
