RTM-ATCA-SXXX Overview

4.8Link aggregation and bonding

The ATCA-S201 supports 802.3ad link aggregation also known as “bonding”. Bonding allows you to aggregate multiple Ethernet ports into a single group, effectively combining the bandwidth into a single connection. For example, you can aggregate the ATCA base channel ports (1 Gb/s each) into a trunk group, providing 2Gb/s cumulative bandwidth, fault tolerance and load balancing.

Base channel bonding			Base channel
example	Switch 1		bonding
Eth0	Switch 1	Eth0	Host
Eth0		Eth0	Host
Bond0			Bond0
Eth1	Switch 2	Eth1

The Linux bonding driver provides the ability to group ports, detect link failures and reroute traffic to the surviving ports in a manner transparent to the storage participants.
