Striping is a scheme that partitions data into blocks and distributes the blocks on different servers in a well defined order and thus could improve system capacity through load balance. In this paper, we propose a parallel VOD server and striping policies for load balancing when extra storage nodes are attached to a parallel VOD server for insufficient disk space in that VOD server. When new video data is stored on the attached storage node, the node may be overloaded. Since it decreases the system bandwidth, appropriate striping policies are required. We therefore present three striping policies that move some block of data o existing nodes into the new node and distribute the new data across all the storage nodes including the new node. Our experiment result shows that FSM bi-direction is the most effective technique.
