Cable Connection When One Controller Enclosure Is Deployed
Connect the cables for the host-to-storage network, HyperMetro replication network, quorum network, and management network.
Dual-Controller Connection
Figure 5-2 uses OceanStor Dorado 3000 V6 as an example to show how switches, controller enclosures, and application hosts are connected in and across DCs.
- The numbered ports are connections within a DC and the lettered ports are connections across DCs.
- For connections within a DC, connect the ports with the same numbers; for connections across DCs, connect the ports with the same letters.
- For details about cable connections between disk enclosures and controller enclosures, see "Connecting Disk Enclosures" in the installation guide corresponding to your product model.
Four-Controller Connection
Figure 5-3 uses OceanStor Dorado 8000 V6 as an example to show how switches, controller enclosures, and application hosts are connected in and across DCs.
- The numbered ports are connections within a DC and the lettered ports are connections across DCs.
- For connections within a DC, connect the ports with the same numbers; for connections across DCs, connect the ports with the same letters.
- For details about cable connections between disk enclosures and controller enclosures, see "Connecting Disk Enclosures" in the installation guide corresponding to your product model.
Table 5-3 explains the cable connection principles (using Fibre Channel networking as an example).

An Ethernet switch is used for management. The management network ports of the hosts and storage controllers are connected to one Ethernet switch of the DC. |
