Cable Connection When Multiple Controller Enclosures Are Deployed
This section describes how to connect the networks if the storage systems are scaled out (controller expansion).
For details on how to add controllers to a storage system, see the installation guide corresponding to your product model.
Four-Controller Connection
Figure 5-4 uses OceanStor Dorado 3000 V6 four-controller deployment 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 5-4 explains the cable connection principles (using Fibre Channel networking as an example).
