In the example, Gateway 1 is connected to Port A on each Array, and Gateway 2 is
connected to Port B on each Array.
Note: It is important that the Gateways be cabled to the Arrays using identical slots
for HA pairs. That is, if PCIe Slot 1 on Gateway 1 is connected to Port A on Array
1, then PCIe Slot 1 on Gateway 2 must be connected to Port B on Array 1.
The Gigabit interfaces on each Gateway, eth1 and eth2, are configured as a bonded
interface, eth0. HA configurations require that the management traffic and cluster
traffic both share the same physical links. A bonded network interface provides
port/cable redundancy. There are many types of bonding modes available, some of
which require changing network switch settings. See Network Bond Commands on
page 150 for more information on these modes.
