    • PROBLEM TO BE SOLVED: To suppress competition of processing.SOLUTION: A storage device 1 comprises a plurality of first storage media 4a and 4b that store data redundantly; and a control device 3 that is connected to the first storage media 4a and 4b with a communication line and controls information writing to the first storage media 4a and 4b. The control device 3 includes: a format processing section 3a that performs format processing to each of the first storage media 4a and 4b; a detection section 3b that detects a failure generated in the first storage media 4a and 4b; a control section 3c that makes the format processing 3a stop the format processing according to the failure detection by the detection section 3b and gives an instruction to rebuild the data stored in the failure-causing first storage medium 4b in a second storage medium 4c other than the first storage media 4a and 4b; and a rebuilding processing section 3d that rebuilds the data stored in the first storage medium 4a in the second storage medium 4c according to the instruction by the control section 3c.
    • 要解决的问题:抑制加工的竞争。 解决方案:存储设备1包括冗余地存储数据的多个第一存储介质4a和4b; 以及通过通信线路连接到第一存储介质4a和4b并控制向第一存储介质4a和4b写入信息的控制装置3。 控制装置3包括:对第一存储介质4a和4b中的每一个执行格式处理的格式处理部分3a; 检测部分3b,其检测在第一存储介质4a和4b中产生的故障; 使格式化处理3a根据检测部3b的故障检测停止格式化处理的控制部3c,并且在除第二存储介质4c之外的第二存储介质4c中给出重建存储在故障的第一存储介质4b中的数据的指令 第一存储介质4a和4b; 以及根据控制部分3c的指令重建存储在第二存储介质4c中的第一存储介质4a中的数据的重建处理部分3d。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To reduce the number of writings into a storage medium.SOLUTION: A controller 3 is a device to control the writing of information into storage media 4a to 4d which are connected with a communication line. A cache memory 3a temporarily stores first information D1 written in the storage media 4a to 4d. A reception part 3b receives second information D2 which takes the first information D1 written in the storage media 4a t 4d as an object of update. In the case that the first information D1 does not exist in the cache memory 3a when the second information D2 received by the reception part 3b is written in the storage media 4a to 4d, a writing control part 3c determines matching between the first information D1 and the second information D2 using comparison information read from the storage media 4a to 4d so as to compare the first information D1 and the second information D2, and when it is determined that the second information D2 matches the first information D1, avoids the writing into the storage media 4a to 4d of the second information D2 determined to match the first information D1.
    • 要解决的问题:减少写入存储介质的数量。 解决方案:控制器3是用于控制与通信线路连接的存储介质4a至4d中的信息写入的装置。 高速缓存存储器3a临时存储写入存储介质4a至4d中的第一信息D1。 接收部分3b接收将写入存储介质4a t 4d中的第一信息D1作为更新对象的第二信息D2。 在由接收部3b接收到的第二信息D2写入存储介质4a〜4d的情况下,在高速缓存存储器3a中不存在第一信息D1的情况下,写入控制部3c确定第一信息D1和 第二信息D2使用从存储介质4a至4d读取的比较信息,以便比较第一信息D1和第二信息D2,并且当确定第二信息D2与第一信息D1匹配时,避免写入 被确定为匹配第一信息D1的第二信息D2的存储介质4a至4d。 版权所有(C)2012,JPO&INPIT
