Preferred Primary Adapter With multiple adapters installed, you can specify one as the Preferred Primary adapter. For example if you have a server with an Intel® PRO/1000 Server Adapter as the primary adapter and an Intel® PRO/100+ Server Adapter as the secondary, you could configure the PRO/1000 Server Adapter to be the preferred primary. In this scenario, if the PRO/1000 Server Adapter fails, the PRO/100+ Server Adapter takes over. Then when the PRO/1000 Server Adapter is replaced, it automatically reverts to being the primary adapter in the team. If a Preferred Primary is not selected, Intel® PROset will attempt to select the best adapter, based on adapter model and speed. Adaptive Load Balancing Adaptive Load Balancing (ALB) is a simple and efficient way to increase your server's transmit throughput. With ALB you group server adapters in teams to provide an increased transmit rate (up to 8 Gbps) using a maximum of eight adapters. The ALB software continuously analyzes transmit loading on each adapter and balances the rate across the adapters as needed. Adapter teams configured for ALB also provide the benefits of AFT. Receive rates remain at 100 Mbps or 1 Gbps depending on the primary adapter's capability. To use ALB, you must have two to eight server adapters installed in your server and linked to the same network switch. Cisco† Fast EtherChannel Fast EtherChannel (FEC) is a performance technology developed by Cisco to increase your server's throughput. Unlike ALB, FEC can be configured to increase both transmission and reception channels between your server and switch. FEC works only with FEC-enabled switches, such as the Catalyst 5000 series. With FEC, as you add adapters to your server, you can group them in teams to provide up to 18 Gbps at full duplex, with a maximum of eight server adapters. The FEC software continuously analyzes loading on each adapter and balances network traffic across the adapters as needed. Adapter teams configured for FEC also provide the benefits of AFT. To use FEC, you must have two, four, or eight server adapters installed in your server and linked to the same FEC-enabled Cisco switch. 144 Intel SPSH4 Server Platform Product Guide
