    • A first storage system is connected to a second storage system, and an external device within the first storage system is provided to a host as a device of the second storage system. The second storage system includes a cache control section having cache adaptors, each controlling a disk and a cache, a protocol conversion section including protocol adaptors that switch requests from the host to appropriate ones of the cache adaptors, a management adaptor, and an internal network that mutually connects the cache adaptors, the protocol adaptors and the management adaptor. The first storage system being connected to any of the protocol adaptors is connected to the second storage system. The second storage system executes a processing for the external device by the cache control section, or connects to the first storage system through the protocol conversion section without the cache control section executing processing for the external device.
    • 第一存储系统连接到第二存储系统,并且第一存储系统内的外部设备作为第二存储系统的设备被提供给主机。 第二存储系统包括具有高速缓存适配器的高速缓存控制部分,每个高速缓存适配器各自控制磁盘和高速缓存,协议转换部分包括协议适配器,其将来自主机的请求切换到适当的缓存适配器,管理适配器和内部网络 相互连接缓存适配器,协议适配器和管理适配器。 连接到任何协议适配器的第一存储系统连接到第二存储系统。 第二存储系统由高速缓存控制部分执行对外部设备的处理,或者通过协议转换部分连接到第一存储系统,而没有高速缓存控制部分执行用于外部设备的处理。
