5.7.3 Teaming

Teaming types
Teaming has the following types.
• Adapter Fault Tolerance (AFT)
Adapter Fault Tolerance (AFT) is a technology to make the link between the server and switches
redundant by using multiple LAN ports. When a failure occurs in the link being used (Primary Link),
the communication continues by switching the process to the standby link (Secondary Link) without
interrupting. For AFT, all ports in the team must be connected to the same switch.
• Adaptive Load Balancing (ALB)
Adaptive Load Balancing (ALB) is a technology that distributes the sending and receiving data to
multiple LAN ports to improve the performance in addition to redundancy function of AFT (When
"Receive Load Balancing (RLB)" in Advanced setting is set to "Disabled", the reception is done only
in the Primary Link). For ALB, all ports in the team must be connected to the same switch as well as
AFT.
• Switch Fault Tolerance (SFT)
Switch Fault Tolerance (SFT) is a redundancy function equal in configuration to AFT when LAN
ports are connected to a separate switch. SFT switches the link to be used between LAN ports and
switches that are connected to the LAN ports when a failure occurs. However, a failure in links
outside of the switches (←, ↓, and → in the figure below) cannot be detected.
PRIMERGY
• Static link aggregation
Select this mode when connecting a team to a Cisco FEC/GEC compliant switch or a switch that
supports IEEE802.3ad-Draft Static. Switch settings are also necessary. All ports in the team must be
connected to the same switch.
• IEEE802.3ad dynamic link aggregation (only for Windows Server 2008)
Select this mode when connecting a team to a switch which supports IEEE802.3ad compliant Link
Aggregation Control Protocol (LACP).
In this mode, all adapters must run at the same speed, and all ports in the team must be connected to
the same switch.
Also, this mode is only available for Teaming on the LAN card.
