摘要:
It is an object of the present invention to provide an engine control apparatus for detecting a voltage abnormality caused in a power supply thereof at low cost. An engine control apparatus for controlling an engine, includes: power supply voltage detecting unit for detecting a power supply voltage of a battery mounted on a vehicle as a power supply, which supplies the engine control apparatus with power; backup power supply voltage detecting unit for detecting a backup power supply voltage of a backup power supply, which supplies the engine control apparatus with power from the battery via a different path; voltage difference calculating unit for calculating a voltage difference between the power supply voltage and the backup power supply voltage; and power supply voltage abnormality determining unit for determining that there is an abnormality in the power supply voltage when the voltage difference is not within a predetermined range.

To provide a file transfer method and system capable of making backups in a unified manner at backup sites and MSP (Management Service Provider) operating under an around-the-clock system with high reliability equipment. When data to be transferred such as backup is transferred between SAN (Storage Area Network) storing units to back up the data stored in the SAN, a data transfer instruction is sent to the transfer source and transfer destination of the data transfer via a network which is different from the SAN.

An assigning system and an assigning method are provided for assigning a storage device or a unitary logical unit of the storage device. A VLU-LU correspondence table is provided which shows a correspondence between virtual logical units (VLU) virtually set in a host computer and logical units (LU) of a plurality of storage devices connected to a network. This table stores evaluation items of each storage device such as a delay time and an access frequency. An evaluation unit calculates an evaluation value of each evaluation item in the table, and a unitary logical unit of the storage is assigned in accordance with the evaluation value.
