Both the requirement of the application and the development of the technology invoke the research of the new networking technology in network storage, currently the IP -based SAN has become the new focus. The main networking technology used in the IP -based SAN is: iSCSI, FCIP, iFCP, mFCP. These protocols all implement the transmitting of SCSI block I/O over the TCP/IP. To understand the protocols deeply, this paper analyzes and compares the protocols intensively.

With the advances in storage subsystems, compression and network technology, video-on- demand (VOD)is increasingly becoming an important services, the investigation to improve the performance of VOD servers has be-come a major focus. In this paper, we propose two rearrangements of data block and a request scheduling *** this approach, the data blocks with comparable access frequency are kept closer to each other, so as to reducethe moving distance of disk head and the seeking time. The simulation result demonstrates that the strategy and algo-rithms can effectively reduce disk access time and response latency respectively.
