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.

解决方案：用于将数据保存在RAID控制器上的高速缓冲存储器中的外部共享高速缓冲存储器连接到每个RAID控制器上的IOP。在其中一个RAID控制器上的高速缓存存储器运行时，相同的数据被写入RAID控制器和外部共享高速缓冲存储器上的高速缓存中。当RAID控制器1发生故障并且RAID控制器1需要切换到RAID控制器2时，RAID控制器2上的IOP将外部共享高速缓冲存储器中的数据复制到RAID控制器2的高速缓冲存储器上，以及然后操作开始。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem of shortage in rewriting resistance that is caused when caching data whose read-access frequency is low and rewriting frequency is high to elevate a cache hit ratio while using a nonvolatile memory having a low rewriting resistance for read caching.SOLUTION: A nonvolatile memory having a high writing resistance is arranged between a volatile memory and a nonvolatile memory having a low resistance capability in a read caching structure. Read-access frequencies to data in the superior volatile memory and the intermediate nonvolatile memory having the high rewriting resistance are monitored. The data storage areas of the superior volatile memory, the intermediate nonvolatile memory having the high rewriting resistance and the interior nonvolatile memory having the low rewriting resistance are controlled in a stepwise manner according to the level of each read access frequency.

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 attain improvement of working rate in a SCSI connected system for SCSI connecting plural targets to an initiator. SOLUTION: In a SCSI connection system for connecting plural target devices 320 to 32n and a host initiator 31 by way of a SCSI bus 33, a transfer rate is automatically set in mediating with regard to the transfer between the initiator 31, the target 320 and so on at the time of activation and a user is notified of this set transfer rate. Also, when some fault occurs during operation of a main system, a transfer rate control part 312 has the target concerned change the transfer speed and tries continuation of the transfer. Moreover, when a phenomenon is not improved even if the transfer rate changed, it is finally judged to be a fatal fault and the user is notified of stop of the transfer and this state of fault.
