Abstract: With the rapid development of computer and network technology, distributed storage based network has became more and more common. The paper designs and implements a network SoftRAID system based dual center-node architecture, which can provide easy-to-use and high-available storage service for systems which need high-capability storage. This paper introduces the architecture, theory and key technology of network SoftRAID system.

Key words: Network SoftRAID; Parallel file subsystem; Data consistency
