在采用层次化存储的并行VOD系统中,若将视频文件进行拆分并把它打散存储在各个存储单元,将获得更高的磁盘利用率.在我们提出的集群式并行视频服务器结构中,数据节点的独立性很强,为提高数据的并发度、负载平衡及容错性,本文提出了一种类似RAID5结构的独立冗余数据节点阵列RAIDN,并讨论了它的容错机制.

In the hierarchical parallel VOD system, video program are always striped across disks/nodes to acquire high availability of disk. In the clustered system, the data nodes have strong independency. In order to improve the concurrency, we put forward a sort of Redundant Array Of Independent Data Node ( RAIDN) , which is similar to RAID 5...
