Abstract :
The paper introduces an IP-based high-available storage network (for short HASN), featured by the following advantages: firstly, it integrates multi-NAS and SAN with OSD through a global multi-protocol file system (for short GMPFS), with greater capacity and better scalability than each of them; secondly, it simultaneously serves both the file I/O and the block I/O by an iSCSI module, with all the advantages of a NAS and a SAN; thirdly, with a storage agency (for short SA), the HASN I/O performance is improved and server bottlenecks are reduced; fourthly, high availability is attained by way of a high-available file system. In addition, in the experiment concerned, the HASN has proved to be a network storage system with great capacity producing an ultra-high-throughput for both the file I/O and the block I/O.
