4.8 Link 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.

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.
