    • In this invention, when execution of an special function executable only by a second storage control apparatus connected to a first storage control apparatus is requested by a higher-level apparatus, the special function is caused to be executed by a second storage control apparatus, and appropriate load balancing is achieved. An executing apparatus judgment section, upon receiving an execution request from a host, uses a function management section and a state detection section to decide which storage control apparatus should execute the function. An execution instruction section issues an instruction to execute the function to the function execution section of the storage control apparatus determined to be the executing apparatus. By this means, even in the case of an special function executable only by a storage control apparatus, the function can be caused to be executed. Hence a connection source storage control apparatus can appear to have increased functionality, without installing the function on the connection source storage control apparatus.

    • A storage system includes a group of storage devices which include back-up devices configured to assure appropriate response time. When a data request from a host computer arrives, and the number of failed devices has changed as shown by a device state management table, a determination is made regarding the number of devices from which to read data. This determination is made based on an indication of redundancy which indicates how many of the disk devices are allowed to be in a failed state at the time of data reading. Typically, the indication of redundancy is determined by the sum of the number of failed devices and a predetermined number. The determined number of devices are selected in accordance with a selection factor, and a selection result is written into a disk management table. Then, the reading process is executed with respect to the target disk devices.
    • 存储系统包括一组存储设备,其包括被配置为确保适当的响应时间的备份设备。 当来自主计算机的数据请求到达并且设备状态管理表所示的故障设备的数量已经改变时,确定从其读取数据的设备的数量。 该确定是基于指示冗余的指示进行的,其指示在数据读取时允许多少磁盘设备处于故障状态。 通常,冗余的指示由故障设备的数量和预定数量的总和确定。 根据选择因素选择确定的设备数量,并将选择结果写入盘管理表。 然后,相对于目标盘装置执行读取处理。
