Abstract: Video on demand (VOD) server requires a large storage capacity and rapid video retrieval from this storage to quickly stream these videos to users. The hybrid storage system, which combines HDDs and SSD in the server, has become popular because of such requirements. The combination of both storage modes is relatively weak in terms of optimising fast access prior and in supporting the production of a high number of simultaneous streams. This paper presents an enhanced hybrid storage system (EHSS)-based VOD server to improve the performance of the VOD server. The design of the EHSS and its streaming management scheme produce high performance and satisfy the performance requirements of a VOD server in terms of I/O throughput and access latency. The experimental results show that the proposed work provides better performance than the VOD server-based FADM because it enhances the average response times for the various scales of intensive workload by 69.89%.
