In a scalable server that supports the retrieval and display of continuous media, both the number of simultaneous displays and the expected startup latency of a display increases as a function of additional disk bandwidth. Based on a striping technique and around-robin placement of data, this paper describes object replication and request migration as two alternative techniques to minimize startup latency. In addition to developing analytical models for these two techniques, we report on their implementation using a scalable server. The results obtained from both the analytical models and the experimental system demonstrate the effectiveness of the proposed techniques.
