    • A device control apparatus includes a processor that operates according to software, a storage unit that stores privileged software which manages an interrupt to the processor from a device included in the device control apparatus, an OS storage unit that stores an Operation System for calling the privileged software from the storage unit when an interrupt from the device is detected during an execution of the software, a detecting unit that detects an interrupt to the Operation System from the device while the Operation System is operating on the processor, a judging unit that judges whether the Operation System has called the privileged software from the storage unit in a first predetermined time from detection of the interrupt to the Operation System from the device, and a resetting unit that resets the processor when the judging unit judges that the Operation System has not called the privileged software from the storage unit.

    • There are two classes of scheduling policy: a first class in which a completion of data transfer requested by a data transfer request within a deadline for completing the requested data transfer, specified for the request, is a primary key factor in determining an order of processing, and a second class in which a reduction of amounts of mechanical actions of a storage device required in carrying out the data transfer requested by the request is a primary key factor in determining the order of processing. Data transfer requests with respect to the storage device are sequentially accepted. Each data transfer request is classified into the second class while the current time has not yet exceeded a time earlier by a certain time than the deadline. Each data transfer request is classified into the first class after the current time has already exceeded the time.
    • 有两类调度策略:在完成请求数据传输的期限内由数据传输请求完成数据传输的第一类是为请求指定的,是确定处理顺序的主要关键因素 以及第二类,其中在执行由请求请求的数据传送所需的存储设备的机械动作的量的减少是确定处理顺序的主要因素。 依次接受关于存储设备的数据传输请求。 每个数据传输请求被分类为第二类,而当前时间还没有比截止日期早一段时间超过一段时间。 在当前时间已经超过时间之后,每个数据传输请求被分类为第一类。

    • A continuous data server capable of reducing a cost for issuing control commands from a central control device to data memory control devices and communication control devices. The central control device issues a control command for each data memory control device and a control command for each communication control device collectively as a single control command set. Alternatively, the central control device issues control commands for the data memory control devices collectively as a single first control command set, and control commands for the communication control devices collectively as a single second control command set, through separately provided communication paths. When the continuous data are striped over data memory devices, the central control device can issue a common control command for all the data memory control devices.
    • 一种连续的数据服务器,其能够降低从中央控制装置向数据存储器控制装置和通信控制装置发出控制命令的成本。 中央控制装置将每个数据存储器控制装置的控制命令和每个通信控制装置的控制命令一起作为单个控制命令集发出。 或者,中央控制装置通过单独提供的通信路径,将数据存储器控制装置的控制命令统一地发送为单个第一控制命令集,以及将通信控制装置的控制命令集体地统一为单个第二控制命令集。 当连续数据在数据存储设备上分条时,中央控制设备可以为所有的数据存储器控制设备发出一个共同的控制命令。

    • A information processing apparatus includes, upon instructing for writing back stored contents of a main memory unit to the stored contents of the main memory unit at the time of previous modification in a sequence number that is used for identifying whether write back to the main memory unit is needed, from a backup data stored in a backup memory unit, the sequence number stored in a sequence number memory unit. The information processing apparatus selects the backup data including an integrity verification data indicating that writing is carried out completely. The information processing apparatus extracts an original data and a write destination address included in the selected backup data and writes the original data, for each original data and the write address extracted from the backup data, to a storage area, of the main memory unit, indicated by the write destination address.
