Scalable network servers are increasingly identified as a critical component in the exponential growth of the Internet. We focus on media servers for variable bit rate streams and study the scalability of alternative disk striping policies, previously known and new. In contrast to results of previous studies, we show that the highest sustained number of streams that can be supported increases almost linearly with the number of disks. We believe that important role for our conclusion play the performance evaluation method that we use and a new disk space allocation technique that we introduce. Also, with reasonable technological projections, our arguments remain valid into the foreseeable future.
