A new distributed storage scheme for cluster video server

Xiaofei Liao, Hai Jin
2005 Journal of systems architecture  
For cluster video servers, it is very important to design a good distributed storage system with high performance.  ...  We have designed a new multimedia data storage scheme for cluster video server. In the new system, a novel multimedia file splitting scheme, named Owl, and a clips striping scheme have been proposed.  ...  Another problem of distributed video servers is fault tolerance. If some storage nodes failed, many movie playing paths will crash and normal playback requests are cut down.  ...

Achieving Reliable Parallel Performance in a VoD Storage Server Using Randomization and Replication

Yung Ryn Choe, Vijay S. Pai
2007 2007 IEEE International Parallel and Distributed Processing Symposium  
This paper investigates randomization and replication as strategies to achieve reliable performance in disk arrays targeted for video-on-demand (VoD) workloads.  ...  The results indicate that combining randomization and replication allows RDA to effectively tolerate both workload hotspots and fail-stutter faults better than previous schemes.  ...  Since a modern 500 GB commodity disk can hold more than 100 DVD-quality (4.7 GB) multimedia streams, a single 2U video-on-demand server could hold 800 movies.  ...
