Abstract: A channel device equipped with a data buffer unit storing data transferred between a storage device and an input-output device, a transfer controller transferring continuous data between the storage device and the data buffer unit using channel startup information. The storage device transfer controller transfers first data between the storage device and the data buffer unit using first transfer information stored in the address list and transfers the second data using second transfer information and total transfer amount information stored in the address list after the first data is transferred and an input-output device transfer controller transfers the continuous data between the data buffer unit and the input-output device.

Abstract: A CPU obtains the component information of the hardware resources for each partition when dividing a system board and IO unit which are the hardware resources of a computer server, provided by the system manager, into a plurality of partitions and assigning them to the plurality of partitions, and sets a switching hub, based on the component information of these hardware resources.

Abstract: An information processing apparatus connected with an IO device, having a processing unit, a channel device transferring data between the information processing apparatus and the IO device having a activation controller activating the channel device, a storage device having a predetermined area storing a result operation executed by the channel device, an interrupt controller controlling an interrupt required by the channel device to the processing unit, a channel device controller controlling the channel device and a driver writing a request for a first interrupt in the area of the storage device through the channel device and requiring the first interrupt to the processing unit by using the interrupt controller, wherein the processing unit executes driver commands for reading information stored in the area and requesting the first interrupt when the processing unit detects the request for the first interrupt.

Abstract: A server includes a plurality of information processing units that respectively have a central processing unit and a memory, and that perform respective information processings in parallel; a setting-information receiving unit that receives setting information that indicates whether data communication can be performed among the information processing units; and a communication controlling unit that controls the data communication among the information processing units based on the setting information.

Abstract: A first address conversion table stores first address data corresponding to a receiving buffer in a main memory from among address data stored in a page table. A second address conversion table stores second address data corresponding to an area other than the receiving buffer area in the main memory from among the address data stored in the page table. An address-conversion-request determining unit determines whether an address conversion request is for the receiving buffer area. An address converting unit converts the address based on a result of determination by the address-conversion-request determining unit.
