ReadyNAS Teaming and Failover Support

The ReadyNAS network teaming provides a way to aggregate the two network interfaces into a single logical teamed, or bonded, interface.  The teamed interface allows for failover support and can provide for enhanced aggregate performance over a single virtual interface.

The following teaming/bonding options are available.  Note that the option you select may affect the ReadyNAS network performance.  On systems supporting both 1GbE and 10GbE interfaces, avoid mixing different speeds within a team to prevent performance fluctuation.

Round-Robin

Transmit packets in sequential order from the first available interface to the next. This mode provides load balancing and fault tolerance.

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.

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.

IEEE 802.3ad LACP

Creates aggregation groups that share the same speed and duplex settings. Utilizes all interfaces in the active aggregator according to the 802.3ad specification.  You will need a switch that supports IEEE 802.3ad Dynamic link aggregation.

Transmit Load Balancing

Channel 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 Balancing

Includes Transmit Load Balancing plus Receive Load Balancing for IPV4 traffic, and does not require any special switch support. The receive load balancing is achieved by ARP negotiation.
