摘要： An information processing system includes a data processing apparatus and multiple storage apparatuses. The data processing apparatus stores, into a memory, write data to be written to a first storage apparatus, and sends, to the first storage apparatus, a first transfer request containing information of a storing location of the write data in the memory. The first storage apparatus executes a transfer process to read the write data from the storing location, and writes the write data to a first storage area in the first storage apparatus; sends, to a second storage apparatus, a second transfer request instructing a transfer of the write data from the memory to the second storage apparatus; and sends, to a third storage apparatus, a third transfer request instructing a transfer of the write data from the first storage area to the third storage apparatus.

摘要： An apparatus calculates, from information included in a packet, a first value that is used to select a path through which the packet is to be transmitted to a destination apparatus. When the packet is a detection packet used to detect a fault in a communication path to the destination apparatus, the apparatus obtains a second value by performing calculation on the first value and a variable value that is changed each time the detection packet is transmitted, and adds an outer header including the second value to the packet. The apparatus adds an outer header including the first value to the packet when the packet is not a detection packet. The apparatus transmit the packet to which the outer header has been added, to the destination apparatus.

摘要： A plurality of internal queues that receives and stores therein packets and that outputs each of the stored packets is included. Then, a transmission side meter counter and a reception side meter counter acquire transmission/reception information on the packets that are stored in each of the internal queues. A control unit creates, on the basis of the transmission/reception information, flow groups to each of which one or a plurality of flows belongs and allocates the internal queues to the flow groups. A scheduler determines, on the basis of the transmission/reception information and previously determined priority of the internal queues, the order in which each of the internal queues is output.

摘要： An information processing device is configured to store pieces of identification information for identifying a same object, in a case where devices in which the object is to be stored is specified from among information processing devices including the information processing device by calculation using each of the pieces of identification information. The pieces of identification information satisfy that combinations of the devices are the same, the information processing device is included as one of the devices, and primary devices serving as read sources of the object among the devices are different from one another. When one piece of identification information is specified to use the information processing device as the primary device from among the pieces of identification information, and a task arranged by control of a management device is executed to read the object, the primary device is specified based on the one piece of identification information.
