Bonded Network Configuration
The behavior of the logically-bonded ports depends upon the mode. For the RDX QuikStation,
you can configure port bonding for active backup/failover, adaptive load balancing, or dynamic
link aggregation.
The following table describes the port bonding modes that are available in the RDX
QuikStation.
Split Network Configuration
When there is more than one Ethernet interface available to the host, each available interface
is configured separately. Configuration of each separate interface is similar to the
configuration of a single bonded interface above with a few exceptions:
•
An unbonded interface dialog has no bonding mode settings.
•
IP address must be different for all interfaces.
•
Only one default interface can have gateway address set.
•
If one interface is set in DHCP mode, it is considered a default interface.
•
You can configure DNS and search domain only for interface with static configuration,
which has gateway address set.
•
At least one interface must be enabled in a split setup.
NOTE: A split Ethernet port configuration should be used if ports are connected to the different
networks. If ports are connected to the same network setup, use a bonded port configuration.
You may also want to use split Ethernet connection if you choose to allow the Multiple Host
Connections option. See
“Options for RDX QuikStation” on page 55

Port bonding mode
Description
Active-backup (failover)
The Active-backup or failover mode is the default
configuration for the RDX QuikStation. This mode uses one
port (adapter) and is limited by that port’s throughput. It will
only switch to the other port if the active port fails.
Adaptive load balancing
(balance-alb)
Adaptive Load Balancing provides load balancing of transmit
and receive traffic. It also provides automatic failover if one
cable fails. This option works with any switch and is best used
in a multi-cartridge environment that has multiple iSCSI host
connections. This mode can provide a maximum performance
for multiple iSCSI sessions from the different IP addresses.
You might consider using this option if you have configured
your RDX QuikStation as the maximum number of RDX docks,
and you are using most or all of the iSCSI targets.
Dynamic link aggregation
(802.3ad)
Creates aggregation groups that share the same speed and
duplex settings. Utilizes all slave network interfaces in the
active aggregate group according to the IEEE 802.3ad
specification.
Requires 802.3ad support in Ethernet switch and host
computer (iSCSI initiator). This mode can be utilized as point-
to-point between RDX QS 4 and the initiator host.This mode
can provide a maximum performance for a multiple iSCSI
session from the same IP address.
If the network is not configured properly, using this port
bonding mode can disrupt the entire network.
