    • A storage system includes a network adapter, a channel adapter, a shared memory, a cache memory, a disk adapter, a switch and a storage device. The storage device stores data. The network adapter includes a port connected to a local area network, and a NAS processor and an I/O processor. The NAS processor receives a file access request via the port, and gives instructions to access the data stored in the storage device as well as instructions to back up the data stored in the storage device. The I/O processor transfers access to the data stored in the storage device to the cache memory, and transfers backup instructions for the data stored in the storage device to the shared memory. The channel adapter includes a port and an I/O processor. The I/O processor sends out data stored in the storage device to the device storing backup data, in response to a backup instruction from the network adapter.
    • 存储系统包括网络适配器,信道适配器,共享存储器,高速缓冲存储器,磁盘适配器,交换机和存储设备。 存储设备存储数据。 网络适​​配器包括连接到局域网的端口,以及NAS处理器和I / O处理器。 NAS处理器通过端口接收文件访问请求,并且给出访问存储在存储设备中的数据的指令以及备份存储在存储设备中的数据的指令。 I / O处理器将存储在存储设备中的数据的访问转移到高速缓冲存储器,并将存储在存储设备中的数据的备份指令传送到共享存储器。 通道适配器包括端口和I / O处理器。 响应于来自网络适配器的备份指令,I / O处理器将存储在存储设备中的数据发送到存储备份数据的设备。
