Abstract: iSCSI is a network storage protocol based on TCP/IP.It has advantages such as convenience of setting up,high expansibility over long distance,etc.But in practical situation,expensive hardware has to be deployed,e.g.,HBA network interface card,to get high performance.Based on high-performance and common compute,storage and network technology,we designed a iSCSI-oriented software defined storage area network(iSCSI-SDSAN) to improve iSCSI SAN’s access performance without specific hardware.The iSCSI-SDSAN’s architecture,component and algorithm are discussed in the paper.In the end,implementation on Ubuntu using Java shows the IO performance improved largely especially for writing bandwidth with 30% increase.

Key words: iSCSI,Software defined storage,iSCSI performance
