  • SX are even numbers for device addresses and sub-networks
  • DX are odd numbers for device addresses and sub-networks

Link Aggregation

  1. CentOS 6 Channel Bonding
  2. Bonding interfaces for CentOS
  3. Linux kernel bonding notes

Bonding Evaluation

The Linux bonding driver provides a method for aggregating multiple network interfaces into a single logical "bonded" interface. For testing, we use UDP traffic generator from several computers over a Gigabit Ethernet switch network. The used mode is adaptive load balancing (mode=6). The final throughput was the expected one based on the generated load.

Pro:
  1. Provides load balance and fault tolerance. For testing, we unplug one cable and the system sent the traffic to the available ethernet interface
  2. Simple to setup
  3. Available in Centos 6 (target platform so far)
  4. No special switches or configurations are needed
  5. Supports VLAN.

Contra:
  1. Ethtool support in the base drivers for retrieving the speed of each slave
  2. Base driver support for setting the hardware address of a device while it is open
