Abstract

iSCSI is an emerging communication protocol enabling block data transport over TCP/IP network. This paper uses a storage architecture allowing parallel processing of iSCSI commands and presents two novel techniques for improving the performance of iSCSI protocol - the first is the elimination technique for reducing latency caused by redundant overwrites and second technique reduces the latency caused due to multiple reads to same storage sector. The theoretical performance analysis shows that use of operation semantics has the potential to improve performance as compared to the existing iSCSI protocol.
