Linux Bond
~~~~~~~~~~
-Bonding is a technique for binding multiple NIC's to a single network
-device. It is possible to achieve different goals, like make the
-network fault-tolerant, increase the performance or both
-together.
+Bonding (also called NIC teaming or Link Aggregation) is a technique
+for binding multiple NIC's to a single network device. It is possible
+to achieve different goals, like make the network fault-tolerant,
+increase the performance or both together.
+
+High-speed hardware like Fibre Channel and the associated switching
+hardware can be quite expensive. By doing link aggregation, two NICs
+can appear as one logical interface, resulting in double speed. This
+is a native Linux kernel feature that is supported by most
+switches. If your nodes have multiple Ethernet ports, you can
+distribute your points of failure by running network cables to
+different switches and the bonded connection will failover to one
+cable or the other in case of network trouble.
+
+Aggregated links can improve live-migration delays and improve the
+speed of replication of data between Proxmox VE Cluster nodes.
There are 7 modes for bonding:
For the most setups the active-backup are the best choice or if your
switch support LACP "IEEE 802.3ad" this mode should be preferred.
+The following bond configuration can be used as distributed/shared
+storage network. The benefit would be that you get more speed and the
+network will be fault-tolerant.

.Example: Use bond with fixed IP address

-.Example: Use a bond with a bridge
+
+Another possibility it to use the bond directly as bridge port.
+This can be used to make the guest network fault-tolerant.
