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
The dual LAN configuration is of two types as described below:
Adapter Fault Tolerance (AFT)
Adapter Fault Tolerance (AFT) is a feature that places more than one LAN controller on the
same LAN (same segment), and automatically switches the process of the primary controller to
the backup controller when any trouble occurred on the primary.
Adaptive Load Balancing (ALB)
Adaptive Load Balancing (ALB) 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 receiving
throughput is enhanced.
