Abstract

In the Storage Area Network (SAN), the mature network technology is used to substitute for the IO bus. Usually, the common switch is used in the storage network especially in the iSCSI storage system. Because the common switches are not aware of the environment it is used in, it can not make optimization for the storage network. In this paper, an optimization of storage network is presented which can greatly improve the performance and resource utilization of the whole storage system. In this optimization, the IO acknowledgment commands passing through the switch which is used in storage network are transferred in highest priority. This optimization of SAN has been certified by the simulation experiments.
