Efficient disk-to-disk copy through long-distance high-speed networks with background traffic

Abstract

We propose “ICDC – InterContinental Disk Copy”, a data sharing facility between distant places. ICDC aims to transfer huge amount of data files easily on Long Fat-pipe Networks with some background traffic. ICDC consists of commodity PCs and Solid State Drives and we apply Inter Packet Gap tuning technique to it. Using “ICDC-1 Gbps model”, we transferred data between Tokyo and Cadarache via New York. We attained about 860 Mbps, i.e., 86% usage of the network bottleneck bandwidth.
