    • A disk array system has a disk storage group, an array controller reading/writing data of the group, a disk interface connecting unit having a plurality of ports for connection with the controller and the group, and a disk interface connection changing unit. In an array configuration information memory, information indicating a relation between the controller and the group is stored. An array configuration changing portion changes the array configuration information in response to a user's request. A connection changing interface informs the changing unit of a connection change based on the changed array configuration information. The changing unit sends instruction information on setting up the connection status among the ports to the connecting unit to establish the configuration indicated by the array configuration information. The connecting unit changes the port connection according to the instruction information sent from the changing unit.
    • 磁盘阵列系统具有磁盘存储组,阵列控制器读/写组的数据,具有用于与控制器和组连接的多个端口的磁盘接口连接单元和磁盘接口连接改变单元。 在阵列配置信息存储器中,存储表示控制器与组之间的关系的信息。 阵列配置改变部分响应于用户的请求改变阵列配置信息。 连接改变接口基于改变的阵列配置信息通知改变单元的连接改变。 更改单元向连接单元发送关于设置端口之间的连接状态的指令信息,以建立由阵列配置信息指示的配置。 连接单元根据从更换单元发送的指令信息更改端口连接。
