Step 5: Set Dual LAN Configuration
The NEC Express5800/ft series builds a dual LAN configuration by using "Intel(R) PRO/1000 MT
Dual Port Network Connection" and extended PCI slot "Intel(R) PRO/1000 MT Server Adapter,”
“Intel(R) PRO/1000 MF Server Adapter” mounted as standard on the CPU/IO module.
Overview
There are two kinds of Dual LAN configurations below.
z Adapter Fault Tolerance (AFT)
Adapter Fault Tolerance is a feature to switch to the backup controller immediately and
continue the operation if the primary controller fails, by placing more than one LAN controllers
on the same LAN (same segment).
z Adaptive Load Balancing (ALB)
Adaptive Load Balancing (ARB) is a feature that connects more than one LAN controller to the
same hub, and enhances the throughput by operating packet transmission from the server.
Receive Load Balancing (RLB) is enabled by default. When RLB is enabled, the receive
throughput is enhanced.
