CAUTION:
If you change the host card type in the same slot, the system needs to

be reset to factory default to make the host card change effective. If
you want to learn more about how to reset your system to factory,
please refer to the chapter 6.5.5, Rest to Factory Default section in the
XCubeSAN SANOS 4.0 User's
All dual controller XCubeSAN series models must have installed the

same type of host cards into the same slot number to keep the
optimized system performance.
INFORMATION:
 Due to the total bandwidth of slot 2 is 20Gb. It CAN NOT satisfy four
ports of 10GbE iSCSI with full speed, we strongly recommend
combining two ports by enabling link aggregation for failover. Such as
combining port 1 and port 2 as LAG (Link Aggregation Group) 1, port 3
and port4 as LAG 2. If you want to learn more about how to setup link
aggregation, please refer to the chapter 7.3.1, Configure iSCSI Ports
section in the
