CAUTION:
Before using trunking or LACP, the gigabit switch must support either trunking or LACP.
Otherwise, host cannot connect the link with storage device.
Dual Controllers
Dual controllers of the same type for redundancy are supported. Controller 1 (CTRL 1) is the master
controller and controller 2 (CTRL 2) is the slave by default.
CAUTION:
If you try to increase the system memory and running in dual controller
mode,
please make sure both controllers have the same DIMM on each corresponding
memory slot. Failing to do so will result in controller malfunction, which will not
be covered by warranty.
Be aware that when the LED of the Controller Health is in RED, please DO NOT
unplug the controller from the system or turn off the power suddenly. This may
cause unrecoverable damage, which will not be covered by warranty.
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
