Table 4

provides a feature comparison across the team types supported by Dell. Use this table to determine the best type of

team for your application. The teaming software supports up to eight ports in a single team and up to 16 teams in a single
system. These teams can be any combination of the supported teaming types, but each team must be on a separate network
or subnet.

Selecting a Team Type

The following flow chart provides the decision flow when planning for Layer 2 teaming. For TOE teaming, only Smart Load
Balancing™ and Failover type team is supported. The primary rationale for teaming is the need for additional network
bandwidth and fault tolerance. Teaming offers link aggregation and fault tolerance to meet both of these requirements.
Preference teaming should be selected in the following order: Link Aggregation as the first choice, Generic Trunking as the
second choice, and SLB teaming as the third choice when using unmanaged switches or switches that do not support the first
two options. if switch fault tolerance is a requirement, then SLB is the only choice (see

Figure 1

).
