Provided is a wind power generation apparatus to which general purpose inverters are applicable. An inverter in a constant-voltage mode is used. While a wind power generator is generating electricity, switching circuits are turned on and off at a controlled duty cycles to intermittently short-circuit an armature winding, boosting the voltage and controlling the rotational speed of a windmill rotating blade, with the result that the voltage applied to the inverter is made constant. At the activation, in order to prevent an excessive voltage from being generated while an inverter is changing from the stand-by state to the activated state, ON/OFF control of a switching circuit is performed to switch between the output voltage of a rectifier and the voltage generated at a resistor, with the result that the voltage is controlled and maintained at an appropriate value.

In storage subsystems, due to the significant increase in HDD capacity, the time for executing online verification is elongated, affecting accesses from the host computer. By comprehending the status of accesses to the HDD, the sections where error has occurred and the status of restoration thereof, it becomes possible to detect defective or error sections efficiently at an early stage, according to which the reliability and access performance of the storage subsystem can be improved. The present storage subsystem executes one or more of the following processes: (M1) intensive verification of a circumference of an error LBA, (M2) an area-based prioritized verification, and (M3) continuous verification performed for a long period of time to (V1) an area in which error has occurred via IO access, (V2) a highly accessed area, and (V3) during a period of time when IO access is low.

Storage subsystem and method for controlling the same

Times at which requests for a data read or data write from/to a logical volume are received are stored in memory as access times of a RAID group making up the logical volume. When a predetermined time has elapsed after the access time, a number of the hard disk drives according to the redundancy of the RAID group are set to a power saving mode. Assume there are first hard disk drives and second hard disk drives having shorter lifes and the RAID group exceeds a predetermined time after the access time. When the RAID group consists of only the first drives, a number of the first drives according to the redundancy of the RAID group are set to a power saving mode and when it consists of only the second drives, an arbitrary number of second drives are set to a power saving mode.
