摘要： A direct memory access (DMA) controlled system which performs DMA data transfer between a main memory, a cache memory, and disk memories while exchanging DMA transfer requests and acknowledgements among disk control units, a memory-to-memory transfer control unit, and a common DMA control unit. The data transfer speed between the main memory and the cache memory is variable according to the load condition of the DMA control unit for the disk memories, enabling the transfer capability of the DMA control unit to be kept at a continually high level.

摘要： A system performs the power supply control of a plurality of information processing apparatuses at a low cost without relation to the intrinsic function of the information processing apparatus and the existence of a network facility. The power supply control apparatus of the present invention can be connected to at least one information processing apparatus. The power supply control apparatus comprises a power supply circuit that supplies electrical power to the information processing apparatus, a network connecting unit that connects a network with an administration apparatus for detecting a failure in operating conditions of the information processing apparatus, and a power supply control unit that controls power supply of the supply circuit on the basis of a power supply on/off instruction received from the administration apparatus via the network connecting unit.
