Abstract: The key structure of the remote fiber storage network in Tianjin Port of China was developed. The expansibility and data transport protocols were analyzed. The link power budget formula was presented in the long distance optical fiber at the data speed of 10 Gbit per second. It is concluded that the method of merging iSCSI and FC SAN is feasible in designing and implementing remote fiber storage network, which keep the performance steady and decrease the cost. The practical system was implemented successfully.
