ABSTRACT:
With a storage system including a drive and a controller, which are connected to each other via cables, and with a method for controlling the storage system, an emergency power supply voltage for a power failure at the drive is multiplexed at the controller with a first signal to be sent to the drive, and the resultant emergency power supply voltage is sent via the cable to the drive. When a power failure occurs at the drive, the drive is powered with the emergency power supply voltage sent from the controller, and specified power failure information is multiplexed at the drive with a second signal to be sent to the controller, and the resultant power failure information is then sent via the cable to the controller; and specified processing is executed at the controller in response to the power failure information sent from the drive via the cable. Accordingly, it is possible to realize a storage system and the controlling method therefor that are adequate for practical applications and can sufficiently cope with drive power failures without the need for complication and upsizing of the entire system configuration.
