摘要： The write data is entered from the upper unit into a nonvolatile cache provided in a controller inside of each disk unit through a channel adaptor, a cache shared by each disk, and a disk adaptor. The data from the cache is compressed by the data compressing and restoring device and is written in the disk. At a time, the management information for compressed data is written in the cache and the disk as well. In case of breaking the management information of the cache when a failure takes place in the cache memory, the management information is written for each disk. Hence, the breakage does not have an adverse effect on the other disks. If the management information of the cache is broken, the management information given into the disk may be replaced with the broken information.
摘要翻译： 写入数据通过通道适配器，由每个磁盘共享的高速缓存器和磁盘适配器从上位机输入到每个磁盘单元内的控制器中提供的非易失性缓存。 来自缓存的数据由数据压缩和恢复设备压缩并写入磁盘。 一次，压缩数据的管理信息也被写入高速缓存和磁盘。 在高速缓冲存储器中发生故障时破坏缓存的管理信息的情况下，为每个盘写入管理信息。 因此，破损对其他磁盘没有不利影响。 如果高速缓存的管理信息被破坏，则可以用损坏的信息替换给予该盘的管理信息。
