Bonding is available only on ReadyNAS systems with two or more Ethernet interfaces.Note:
Teaming Modes
The ReadyNAS supports several teaming modes. Both the ReadyNAS and the device with which the
bonded adapter is linked must support the same teaming mode.The available teaming modes are described
in the following table.
Table 22.Teaming mode descriptions
DescriptionTeaming Mode
Creates aggregation groups that use the same speed and duplex settings. Utilizes all
interfaces in the active aggregator according to the 802.3ad specification.You need a
switch that supports IEEE 802.3ad dynamic link aggregation.
IEEE 802.3ad LACP
Only one interface in the bond is active. A different interface becomes active if, and
only if, the active interface fails.The bond’s MAC address is externally visible on only
one port to avoid confusing the switch.You can decide which interface is active by
default.
Active Backup
Adapter bonding that does not require any special switch support.The outgoing traffic
is distributed according to the current load (computed relative to the speed) on each
interface. Incoming traffic is received by the current interface. If the receiving interface
fails, another interface takes over the MAC address of the failed receiving interface.
Transmit Load Balancing
Includes transmit load balancing plus receive load balancing for IPV4 traffic and does
not require any special switch support.The receive load balancing is achieved by ARP
negotiation.
Adaptive Load Balancing
Transmit packets in sequential order from the first available interface to the next.This
mode provides load balancing and fault tolerance.
Round-Robin
Transmit based on the default simple transmit hash policy.This mode provides load
balancing and fault tolerance.
XOR
Transmit everything on all slave interfaces.This mode provides fault tolerance.Broadcast
Hash Types
If you select the IEEE 802.3ad LACP or the XOR teaming mode, you must select which hash type option
you want to use:
•Layer 2
•Layer 2+3 (uses Layer 2 and Layer 3 hash types simultaneously)
•Layer 3+4 (uses Layer 3 and Layer 4 hash types simultaneously)
Each hash type is described in the following table.
