摘要： PROBLEM TO BE SOLVED: To take over data in a cache memory at the time of switching operation in an RAID controller group with redundancy having n levels.SOLUTION: An external shared cache memory for holding data in cache memories on RAID controllers is connected to an IOP on each RAID controller. At the time of operation with the cache memory on one of the RAID controllers active, identical data is written onto the cache memory on the RAID controller and the external shared cache memory. When failure occurs in an RAID controller 1 and the RAID controller 1 needs to be switched to the RAID controller 2, the IOP on the RAID controller 2 duplicates the data in the external shared cache memory onto the cache memory of the RAID controller 2, and then operation starts.

摘要： PROBLEM TO BE SOLVED: To reduce vibration by selecting rotational speed of a disk inside a hard disk device based on a vibration detection means or a rotational speed setting means mounted on the hard disk device without depending on a host device, a host OS or an application program for disk rotation control.
SOLUTION: The hard disk drive device is equipped with a disk shape recording medium 214 for reading or writing information, a motor 213 capable of rotationally driving the disk shape recording medium at multiple rotational speeds and a rotational speed selection part 203 for setting up one rotational speed among the multiple rotational speeds. A vibration sensor 202 is mounted on the hard disk device itself, the rotational speed selection part sets up one rotational speed by the output from the vibration sensor (204). By this setup, the vibration of the chassis for covering an information processing device including the hard disk device is reduced.

摘要： PROBLEM TO BE SOLVED: To hold disk array configuration information in a hard disk device with high reliability without changing a disk array controller and a standard such as SCSI or ATA for exchanging data signal between the disk array controller and the hard disk device.
SOLUTION: A read/write address determination means 105 includes a threshold for determining whether data transferred from a host interface control part 103 is disk array configuration information or not from a write or read address of the data, and accesses a nonvolatile memory 106, when the data is disk array configuration information, to read/write disk array configuration information 110. For making the disk array configuration information redundant, the disk array configuration information is held in both the nonvolatile memory 105 and a magnetic disk 109.

摘要： PROBLEM TO BE SOLVED: To easily identify the causes of the occurrence of events by holding an event, such as trouble occurring in a hard disk device, on a disk-like recording medium in the hard disk device along with current time of the occurrence.
SOLUTION: Current time data is transmitted from a disk array controller device to a current time recording part mounted on the hard disk device. When an event, such as trouble, occurs in the hard disk device, current time data is added to time counted by a timer in a microcomputer since power-on of the hard disk device and current time when the event has occurred is calculated and is recorded at the event information recording part on the disk-like recording medium along with the event information.
