[Huawei Storage Documentation-FAQs] How to Set the Working Mode of the SmartIO Interface Module

• The SmartIO interface module supports 8 Gbit/s, 10 Gbit/s and 16 Gbit/s optical modules.

• The SmartIO interface module can provide 8 or 10 Gbit/s Fibre Channel ports, 10 Gbit/s iSCSI ports and 10 Gbit/s FCoE ports.

• The mode of the SmartIO port can be set to FCoE or FC.

• The SmartIO interface module supports three working modes: FC, FCoE/iSCSI, and Cluster. The FC and FCoE/iSCSI modes are used for host service connections, and the Cluster mode is used for multi-controller scale-out connections.

• If the mode of the SmartIO interface module is set to FCoE/iSCSI and the host uses the FCoE protocol, the module must connect to FCoE switches for networking and a 10 Gbit/s optical module is required.

• If the mode of the SmartIO interface module is set to FCoE/iSCSI and the host uses the iSCSI protocol, the MTU value of the SmartIO port must be the same as that of the host.

• If the working mode does not match the installed optical modules, a system alarm will be generated, asking you to replace optical modules or change the working mode.

a. Log in DeviceManager, and click "system".

b. Click the SmartIO interface module or onboard interface. The Interface Module dialog box is displayed.

c. Click Modify and select mode in the Working Mode text box. The new working mode will take effect 5s after the modification.

• If the mode of the SmartIO port is set to FCoE/iSCSI or Cluster on the software interface, the port indicator is in ETH mode and a 10 Gbit/s optical module is required. A 10 Gbit/s optical transceiver does not support GE/10GE autonegotiation.

• If the mode of the SmartIO port is set to FC on the software interface, the port indicator is in FC mode, and an 8 Gbit/s or 16 Gbit/s optical module is required.
