Port Configuration Options
The RDX QuikStation has two Gigabit Ethernet ports to provide failover
protection and high availability network connectivity. In network
environments, it is a common practice to configure two or more external ports
as a single, logical, bonded port using an industry standard feature called Link
Aggregation, also known as port bonding or port trunking.
The behavior of the logically-bonded ports depends upon the mode. For the
RDX QuikStation, you can configure port bonding for either active
backup/failover or adaptive load balancing.
The following table describes the two port bonding modes that are available in
the RDX QuikStation.

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 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-disk environment
that has multiple iSCSI host connections. You might
consider using this option if you have configured
your RDX QuikStation as eight RDX drives, and you
are using most or all of the eight iSCSI disk targets.
