Caution 

Before using trunking or LACP, he gigabit switch must support trunking or 

LACP and enabled. Otherwise, host can not connect the link with storage 

device.

Dual controllers (only for DSN-6410 with 

DSN-640) 

 

5.10.1

 

Perform I/O 

 

Please refer to the following topology and have all the connections ready. To perform I/O 

on dual controllers, server/host should setup MPIO. MPIO policy will keep I/O running and 

prevent fail connection with single controller failure.
