    • A disk array apparatus where, when a failure occurs at a part of a cache memory, a memory area of an I/O processing controller other than the memory area where the failure has occurred is utilized without taking over the whole I/O processing to an I/O processing controller of other system is provided, so that influence of performance degradation can be minimized. In a disk array apparatus including dual cache memories, when a failure occurs at a part of the cache memory, only a memory area where the failure has occurred is closed, and reallocation thereof to another memory area of the same cache memory is conducted to continue an I/O processing.
    • 一种磁盘阵列装置,其中,当高速缓冲存储器的一部分发生故障时,利用除了发生故障的存储区域之外的I / O处理控制器的存储器区域,而不用将整个I / O处理过渡到 提供了其他系统的I / O处理控制器,从而可以使性能下降的影响最小化。 在包括双高速缓冲存储器的磁盘阵列装置中,当在高速缓冲存储器的一部分发生故障时,仅关闭发生故障的存储区域,并且重新分配到同一高速缓冲存储器的另一个存储区域以继续 一个I / O处理。
