2.7 Load Balancing, Fail-Over (LBFO) and VLAN
Windows 2012 Microsoft supports load balancing as part of the operating system. plese refer to
Microsoft document “Windows 2012 Link Teaming”. However, in previous operating systems
(Windows 2008, Windows 2008 R2 and Windows 7) we have separate drivers, please see the
below section:
2.7.1 Adapter Teaming
Adapter teaming can group a group of ports inside a network adapters or a number of physical
network adapters into virtual adapters that provide the fault-tolerance and load-balancing func-
tions. Depending on the teaming mode, one or more interfaces can be active. The non active
interfaces in a team are in a standby mode and will take over the network traffic in the event of a
link failure in the active interfaces. All of the active interfaces in a team participate in load-bal-
ancing operations by sending and receiving a portion of the total network traffic.
2.7.1.1 Teaming (Bundle) Modes
1. Fault Tolerance
Provides automatic redundancy for the server’s network connection. If the primary adapter
fails, the secondary adapter (currently in a standby mode) takes over. Fault Tolerance is the
basis for each of the following teaming types and is inherent in all teaming modes.
2. Switch Fault Tolerance
Provides a failover relationship between two adapters when each adapter is connected to a
separate switch.
3. Send Load Balancing
Provides load balancing of transmit traffic and fault tolerance. The load balancing is perform
only on the send port.
4. Load Balancing (Send & Receive)
Provides load balancing of transmit and receive traffic and fault tolerance. The load balancing
splits the transmit and receive traffic statically among the team adapters (without changing
the base of the traffic loading) based on the source/destination MAC and IP addresses.
5. Adaptive Load Balancing
The same functionality as Load Balancing (Send & Receive). In case of traffic load in one of
the adapters, the load balancing channels the traffic between the other team adapter.
6. Dynamic Link Aggregation (802.3ad)
Provides dynamic link aggregation allowing creation of one or more channel groups using
same speed or mixed-speed server adapters.
7. Static Link Aggregation (802.3ad)
Provides increased transmission and reception throughput in a team comprised of two to eight
adapter ports through static configuration.
If the switch connected to the HCA supports 802.3ad the recommended setting is teaming mode
