A new storage scheme for streaming media server cluster

We report on the design, implementation of a non equal scheme in streaming media data storage. According to the characteristics of the streaming media and considering the human beings usage, our scheme combines n-way mirroring and erasure-coding together to storage streaming media data. It is make good tradeoffs between system fault tolerance and sufficient quality of service streams. The system has the optimal storage efficiency and the remarkably fault-tolerant capability. At last the design of the non-equal streaming media data cluster storage system is introduced in detail, and an intensive performance evaluation study on it is performed.
