ReadyNAS OS 6.0

Configure Bonded Adapters

Creating a bonded adapter is optional. A bonded adapter combines two Ethernet interfaces into a single logical link. Network devices treat the bonded adapter as a single link, which increases fault tolerance and provides load sharing.

Teaming Modes

The ReadyNAS supports several teaming modes. Both the ReadyNAS and the device with which the bonded adapter is linked need to support the same teaming mode. The available teaming modes are described in the following table.

Table 9. Teaming mode descriptions

Teaming Mode

Description

 

 

IEEE 802.3ad LACP

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.

 

 

Active Backup

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.

Transmit Load Balancing

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.

 

 

Adaptive Load

Includes transmit load balancing plus receive load balancing for IPV4 traffic and does

Balancing

not require any special switch support. The receive load balancing is achieved by

 

ARP negotiation.

 

 

Round-Robin

Transmit packets in sequential order from the first available interface to the next. This

 

mode provides load balancing and fault tolerance.

XOR

Transmit based on the default simple transmit hash policy. This mode provides load

 

balancing and fault tolerance.

 

 

Broadcast

Transmit everything on all slave interfaces. This mode provides fault tolerance.
