Abstract

To work out a network storage system with a large capacity, a high I/O speed, availability and scalability, a iSCSI-based NAS cluster (iNASC) has been designed. Firstly, the iNASC integrates multi-NAS with the storage virtualization and redundancy technologies, which can provide a greater capacity, higher availability and scalability; secondly, the iNASC simultaneously serves for both the file I/O and the block I/O with an iSCSI module, which has the advantages of NAS and SAN; thirdly, the parallel file I/O performance is improved by a parallel FTP module; finally, the iNASC can provide higher I/O speed by a high speed IP channel which implements the direct data transfer between the NAS and client. In the experiments, the iNASC has ultra-high-throughput for the file I/O and block I/O requests.
