Management Port

Management is provided by the Intel
connect to the QES desktop of the ES1686dc. The default ES1686dc management website is
169.254.100.100:8080. If the NAS has been configured to use DHCP, you can use the QNAP Qfinder Pro to
check the IP address of the NAS. Make sure the NAS and the computer that runs the QNAP Qfinder Pro are
connected to the same subnet.
The system requires that the management IP addresses are configured on both controllers and that the
controllers' management ports are connected to the management network. This should be a separate LAN
or a VLAN because you should not use the production LAN or VLAN for management network traffic. To
configure the management port IP Address, refer to the QES User Guide. If one storage controller fails, you
can enable takeover function from the High Availability app in QES to manage the system through the
management port of the other storage controller with the same IP address. For more information, see the
QES User Guide.

Multipath I/O Network Configuration

Multipath I/O (MPIO) is a fault-tolerance technique where more than one physical network path is created
between a server and a storage device such as a NAS. If any one network path goes down due to the failure
of a switch, cable, or network card, the server can route I/O through the remaining network paths with no
storage downtime. The ES1686dc supports MPIO on iSCSI connections using standard Ethernet
infrastructure.
The following diagram is an example of how the multipath I/O should be implemented:
