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
SANOS 4.0 Software Manual.
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
SANOS 4.0 Software Manual.
