摘要： A queue number acquiring unit acquires a command queuing number that is the upper limit of the number of process-waiting instructions that can be stored in each of storages that make up a virtual disk for each storage. A minimum queue number selecting unit selects the minimum value of the command queuing numbers of the storages that make up the virtual disk as a minimum queue number. A queue number setting unit sets the selected minimum queue number as the command queuing number of the virtual disk that includes the storage device of which the command queuing number is selected as the minimum queue number for each virtual disk.

摘要： A node according to the present invention, in a node which is to be instructed by a master node and communicates with an electronic device, performs an activation query notification to the master node. If it is determined that a response from the master node has not been made, the electronic device is allowed to communicate without an instruction from the master node, and it is also determined whether any other node is connected or not. If it is determined that some other new node is connected, the node instructs the other new node to communicate with the electronic device.

摘要： Relay devices each include a port connected to a communication channel that is used to transfer and receive an access request to and from another relay device; a first virtual area section that is set as a virtual memory area that receives an access request; and a second virtual area section set as a virtual memory area for receiving an access request transferred from another relay device. The relay device sends, if a channel to a storage device is in operation, the access request that is sent to the first virtual area section and the access request that is sent to the second virtual area section, to the storage device via the channel. The relay device transfers, if the channel is not in operation, the access request sent to the first virtual area section, to another relay device via the communication channel connected to the port.
