General Configuration Notes 1. Windows NT versions prior to 4.0 don't support Adapter Teaming options. 2. Adapter Teaming options require NT 4.0 with Service Pack 4.0 or Service Pack 3.0 and Hotfix. 3. In Windows NT, teaming options cannot be implemented on adapters that have been configured for VLANs. NetWare can support teaming options and VLANs on the same adapters. Adapter Fault Tolerance Adapter Fault Tolerance (AFT) is a simple, effective, and fail-safe approach to increase the reliability of server connections. AFT gives you the ability to set up link recovery to the server adapter in case of a cable, port, or network interface card failure. By assigning two PRO/100 Intelligent Server adapters as a team, AFT enables you to maintain uninterrupted network performance. AFT is implemented with two PRO/100 Intelligent Server adapters: a primary adapter and a backup, or secondary, adapter. During normal operation, the backup will have transmit disabled. If the link to the primary adapter fails, the link to the backup adapter automatically takes over. Preferred Primary Adapter With multiple adapters installed, you can specify one as the Preferred Primary adapter. For example if you have a server with a PRO/100 Intelligent Server adapter as the primary adapter and a PRO/100+ adapter as the secondary, you would want the PRO/100 Intelligent Server adapter to be the preferred primary. In this scenario, if the PRO/100 Intelligent Server adapter fails, the PRO/100+ will take over. Then when the PRO/100 Intelligent Server adapter is replaced, it will automatically revert to being the primary adapter in the team. If a Preferred Primary is not selected, PROSet will attempt to select the best adapter, based on adapter model and speed. Mixed Adapter Teaming AFT supports up to four PRO/1000 or PRO/100 adapters per team, in any mix. Adaptive Load Balancing Adaptive Load Balancing (ALB) is a simple and efficient way to increase your server's transmit throughput. With ALB you group PRO/100 Intelligent Server adapters in teams to provide an increased transmit rate (up to 400 Mbps) using a maximum of four 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. To use ALB, you must have two, three, or four PRO/100 Intelligent Server adapters installed in your server or workstation and linked to the same network switch. 14 Intel Server Board STL2 Product Guide
