Hyperscsi : Design and development of a new protocol for storage networking

Abstract

In this thesis, we propose a new storage networking protocol, called HyperSCSI, to provide transmission of SCSI commands and data across generic network with the design optimization on Ethernet. We present the details of design and development of HyperSCSI protocol on various platform ranging from corporate Ethernet SAN to home wireless storage network and optical long distance network. We show that HyperSCSI has more design focus on data transportation, which removes TCP/IP protocol stack in order to efficiently utilize the network bandwidth. We propose to use integrated layer processing mechanism to guarantee the data delivery reliability and provide new flow control method for storage data traffic on high speed network. Comprehensive experiments and real applications benchmark measurements have been conducted with the comparison against two leading network storage protocols, FC and iSCSI. The results show that HyperSCSI can achieve significant performance improvement with great reduction of complexity and cost.
