• Make sure that each group in a Dual Channel team is connected to a different switch. If both
groups are attached to the same switch, switch redundancy is lost.
• Whenever a Dual Channel team is created with an even number of teamed ports, evenly
distribute the ports between both groups.
• Ensure all ports in the same group are connected to the same switch.

802.3ad Dynamic Dual Channel Load Balancing

802.3ad Dynamic Dual Channel Load Balancing (Dynamic Dual Channel) functions exactly like
Dual Channel. The differences between Dual Channel and Dynamic Dual Channel are in the
configuration of the team. With Dual Channel, teamed ports must be manually assigned to either
Group A or Group B and the switch ports connected to the teamed ports must have Port Trunking
manually enabled. With Dynamic Dual Channel, teamed ports do not need to be manually
assigned to Groups (A or B) and switch configuration is done automatically with 802.3ad Link
Aggregation Control Protocol (LACP). Dynamic Dual Channel uses information learned from
the LACP negotiation process to automatically group the teamed ports from each switch.
NOTE:
Dynamic Dual Channel load balancing is only available on systems running Windows
Server 2003.
All other aspects of Dynamic Dual Channel are identical to Dual Channel. Refer to the Dual
Channel sections for more details.

802.3ad Dynamic Dual Channel Configuration

Dynamic Dual Channel configuration is easier than Dual Channel configuration. Dual Channel
requires the user to separate teamed ports into two groups in the NCU and requires manual
switch configuration on both switches. Dynamic Dual Channel configuration is identical to
802.3ad Dynamic except that two switches are used instead of one.
To create a Dual Channel team, select at least two network ports on the main NCU page and
click the Team icon. Next, select 802.3ad Dynamic Dual Channel Load Balancing from the Team
Type Selection drop-down box on the Teaming Controls tab. Refer to Figure 4-22.
Lastly, confirm that all switch ports connected to Dynamic Dual Channel network adapter ports
have 802.3ad Link Aggregation Control Protocol (LACP) enabled.

Automatic

The Automatic team type is not really a separate team type. Automatic teams decide whether to
operate as a TLB team or as an 802.3ad Dynamic team. If all teamed ports are connected to a
switch that supports the IEEE 802.3ad Link Aggregation Protocol (LACP) and all switch ports
have LACP enabled, the team will operate as an 802.3ad Dynamic team. However, if the switch
doesn't support LACP or if any ports in the team don't have successful LACP communication
with the switch, the team will operate as a TLB team. As network and server configurations
change, the Automatic team type ensures that HP Integrity servers connect to the network in the
most efficient team type possible.
To monitor which team type Automatic mode uses, refer to the Information tab on the Team
Properties page discussed in the section, "Team Properties Page".
