摘要： In a system which manages path information and status of network with respect to a path being used for access to a storage apparatus and has a redundant path, when a fault occurs in the network, whether or not the path can be recovered by rerouting in network apparatuses is discriminated, thereby performing proper path switching. Construction information and the path information of the network are managed as information of the path which is being used for a storage access by a management server. Further, when the access path is made redundant, the management server obtains fault information in the network and information showing whether or not the path is being reconstructed from the network apparatuses, thereby discriminating the necessity of the path switching. If the path switching is necessary, the management server notifies a host computer and the storage apparatus of it and each apparatus executes a switching process.

A host computer accepts the specification of the device identifier, that is an identifier of the network storage device in the host protocol which positions in a higher hierarchy than the network communication protocol, and a volume identifier, that is an identifier of the volume. Then based on the specified device identifier, the host computer specifies the network identifier, that is an identifier of the network storage device in the network communication protocol. And continuity is confirmed in the network communication protocol in which the specified network identifier is the destination. Also continuity is confirmed in the host protocol in which the device identifier is the destination. And the volume specified by the volume identifier is accessed.

摘要： Storage groups are generated using group information previously set to a switch 3. In a group information acquisition step, group information, which is previously set to the switch 3 and relates to computers 4 and storage devices 5, is acquired from the switch 3, and the acquired group information is stored in a storing means 16. In a node information acquisition step, node information required for connecting to a network is acquired from each of the computers 4 and the storage devices 5, and acquired node information is stored in the storing means 16. In a group generation step, the storage groups are generated based on the group information stored in the storing means 16. And, in a registration step, the generated storage groups and the node information stored in the storing means 16 are registered at a storage name solving server 2.

摘要： A control condition is automatically generated by using a discovery domain managed by an iSNS server as a network communication quality control unit and set in a network device. Thus, it is possible to realize communication whose quality is effectively controlled in storage data transmission. A network configuration server automatically acquires discovery domain information which groups a host and a storage apparatus managed by a name management server. The network configuration server sets a flow identification condition so as to identify the flow per discovery domain according to the information acquired, assigns a service class performing a control of quality of communication service to the flow, and sets transmission rule for the service class to routers.

摘要： The band controller 500 included in the computer system 1000 regularly acquires map information and IF information, etc. from the work server 100, the storage device 200, and the routers 300 and 400, and based on these pieces of information, detects iSCSI sessions for which the communication band is insufficient. When an iSCSI session with insufficient band is detected, the band controller 500 selects another iSCSI session to perform band allocation based on the iSCSI session importance level or the circuit use-rate. The band controller 500 allocates at least part of the communication band of the network route used by the iSCSI session selected in this way to the iSCSI session with insufficient band. The computer system 1000 performs efficient data transfer in storage area networks on which many variations of communication band exist.
