COMMUNICATION SYSTEM, CONTROLLER, SWITCH, STORAGE MANAGEMENT DEVICE, AND COMMUNICATION METHOD

摘要

A communication system includes a server apparatus having an iSCSI initiator, a storage having an iSCSI target, a storage managing apparatus, an open flow controller and open flow switches. The storage managing apparatus stores route data of an iSCSI communication packet for every management ID determined based on an iSCSI initiator name and an iSCSI target name. The server apparatus transmits the iSCSI communication packet in which a management ID is stored in a destination port number. The open flow switch transfers the packet according to the entry. The open flow controller generates and distributes the entry to transfer the iSCSI communication packet to the open flow switch. A communication method is provided in which the flow control is carried out based on the iSCSI data without imposing a high load of the packet processing in the open flow switch by the communication system having the above-mentioned configuration.
