1.3.3 Teaming Function
Broadcom Advanced Server Program (BSAP) Overview
Broadcom Advanced Server Program (BASP) is the Broadcom teaming software for Windows
Server 2003 and Windows 2000 Server operating systems. BASP runs within the Broadcom
Advanced Control Suite 2 (BACS2) utility.
BASP supports four types of teams for Layer 2 teaming:
• Smart Load Balancing and Failover
• Link Aggregation (802.3ad)
• Generic Trunking (FEC/GEC)/802.3ad-Draft Static
• Smart Load Balancing (Auto-Fallback Disable)
` Enabling Windows Server 2003 built-in bridging is not advisable when you are using
teaming software.
For more information on network adapter teaming concepts, refer to "4.3 Teaming Concepts"
(
Jpg.121).
Load Balancing and Fault Tolerance
Teaming provides traffic load balancing and fault tolerance (redundant adapter operation in the event
that a network connection fails). When multiple Gigabit Ethernet network adapters are installed in the
same system, they can be grouped into teams, creating a virtual adapter.
A team can consist of two to eight network interfaces, and each interface can be designated as a
primary interface or a standby interface (standby interfaces can be used only in a Smart Load
Balancing™ and Failover type of team, and only one standby interface can be designated per SLB
team). If traffic is not identified on any of the adapter team member connections due to failure of the
adapter, cable, switch port, or switch (where the teamed adapters are attached to separate switches),
the load distribution is reevaluated and reassigned among the remaining team members. In the event
that all of the primary adapters are down, the hot standby adapter becomes active. Existing sessions
are maintained and there is no impact on the user.
Types of Teams
The available types of teams for the Windows Server 2003/Windows 2000 Server operating systems
are:
• Smart Load Balancing and Failover
