Research on Online Storage Subsystem in VoD
Sun Song-lin · Beijing Youdian Xueyuan xuebao · 2005
Based on the real-time constrain of the multimedia stream and the disk data stream model, the relationship between the performances and the online storage subsystem in video on demand was presented quantitatively with the analysis of memory and interface bus. The experiment shows that the system performance, the maximal throughput and concurrent stream number, are influenced by the combination of disk performance, the redundant arrays of inexpensive disk scheduler, the memory capacity and the bandwidth of interface bus.
