DUAL LAN CONFIGURATION
The NovaScale/ft Server 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.
