The iSCSI protocol is becoming increasingly important as a convenient and cost-effective means of constructing Storage Area Networks (SANs). This paper details a comprehensive overview of performance issues pertaining to the iSCSI protocol with specific focus on latency. In particular, we investigate the performance of iSCSI for sequential accesses in high-latency high-throughput networks. Our performance evaluation demonstrates that the performance of iSCSI degrades with increase in network latency. Moreover, we observe behaviors pertinent to sequential accesses and find evidence of the degradation.
