Striping in Multi disk Video Servers

A challenging task when designing a video server is to support the performance criteria of its target application i e both its desired number of simultaneous displays and the waiting tolerance of a display With a multi disk video server the placement of data has a signi cant impact on the overall performance of a system This study quanti es the tradeo s associated with alternative organization of data across multiple disks We describe a planner that con gures a system to support the performance criteria of an application and minimize the cost of a system The experimental results demonstrate the superiority and exibility of using the planner to con gure a system
