摘要

视频点播(VOD)服务器需要存储数百个电影标题，并支持数千个并发访问。我们将“访问配置文件”定义为VOD服务器应该支持的每个电影标题的并发访问数。当前的高端磁盘阵列只能支持数十个MPEG-2并发访问，并且需要在多个磁盘阵列上复制和/或分条热门电影文件。如何在最少数量的磁盘阵列上复制、分条和放置电影文件，从而支持给定的访问配置文件是一个重要的问题。本文提出并解决了这一问题。研究结果可应用于视频点播服务器存储子系统的设计，以经济地降低成本或使磁盘阵列的利用率最大化。

Video file allocation over disk arrays for video-on-demand

A video-on-demand (VOD) server needs to store hundreds of movie titles and to support thousands of concurrent accesses. We define the 'access profile' as the number of concurrent accesses to each movie title that should be supported by a VOD server. A current high-end magnetic disk array can only support tens of MPEG-2 concurrent accesses, and it is necessary to replicate and/or stripe the hot movie files over multiple disk arrays. How to replicate, stripe and place the movie files over a minimum number of magnetic disk arrays such that a given access profile can be supported is an important problem. In this paper, we formulate and solve this problem. The result of this study can be applied to the design of the storage subsystem of a VOD server to economically minimize the cost or to maximize the utilization of disk arrays.
