Adding Controllers with More Than One Ethernet Port
When your has more than one port, consider these cabling guidelines:
Use one Ethernet port from each controller to connect to your storage array. Use the other Ethernet port from each controller
to connect to an externally accessible network, which allows the Customer and Technical Support representative to access the
storage array. This configuration permits the Customer and Technical Support representative to assist you with troubleshooting
and upgrading your storage array without having access to your data.
When configuring the Ethernet ports, make sure that the port configured for the Customer and Technical Support representative
is on a separate from the storage array port. Configuring both ports with the same subnet causes a “Hardware Ethernet Conflict” error.
When cabling your controllers, be consistent about selecting which port will connect to which network. For example, the Ethernet
ports are labeled 1 and 2 on each controller. Choose port 1 from Controller A and port 1 from Controller B to use to manage
your storage array. Choose port 2 from Controller A and port 2 from Controller B to provide external access for the Customer
and Technical Support representative.
