In realtime multimedia storage servers, it is very important to find the optimal values for the round length and the striping unit size since they have strong relation with the throughput. In getting the optimal values, we should not overlook any factor of multimedia servers since this may produce the wrong values far from the optimal. If we use a wrong value, then we may suffer from 2 or 3 times performace degradation. We present a new scheme which considers all possible factors in multimedia servers such as disk properties, buffer space, the characteristics of multimedia objects, and users' trends of requesting. Since we donot use simple peak data rate but the maximux segment data rate which is much smaller than the peak data rate, we can use the resources very effectively and still guarantees no starvation and no overflow.
