摘要： An information processing apparatus includes a controller, a plurality of electric power supply units and a backup electric power supply unit that supply electric power to the controller. The controller detects a malfunction occurring in the plurality of electric power supply units, stops electric power supply from the plurality of electric power supply units, starts electric power supply from the backup electric power supply unit when a malfunction is detected, identifies an electric power supply unit having a malfunction from the plurality of electric power supply units, disconnects the identified electric power supply unit, resumes electric power supply from an electric power supply unit determined to function normally and stops the electric power supply from the backup electric power supply unit when the electric power supply unit having the malfunction is disconnected.

摘要： According to an aspect of the embodiment, a cache controller sets, when power supply capacity information is acquired at an update period, a size of a permitted area in which the writing of dirty data is permitted and a size of an inhibited area in which the writing of the dirty data is inhibited in a cache memory, according to the power supply capacity information. The cache controller stores the dirty data or read data read out from a disk array in the permitted area, or stores only the read data in the inhibited area.
