10/100Mbps Server Card DFE-580TX DFE-580TX Fast Ethernet server card with 4 10/100Mps auto-sensing ports 4-port Fast Ethernet Server Card The DFE-580TX is a high-performance, versatile server card designed for very fast server connection. Outfit with 4 Fast Ethernet ports, the card gives you a 4-port trunk link from a server to a Fast Ethernet switch, providing load-sharing aggregated bandwidth and redundant backup links, allowing you to cost-effectively run bandwidth-intensive and mission- critical applications in client-server Windows and Unix environments. 4 Fast Ethernet Ports Fail-over Redundant Backups With 4 twisted-pair ports running capable of running at full- An alternative is to configure the card with 2 redundant duplex, the DFE-580TX provides connection at near Gigabit backed-up load-sharing trunks. One trunk is active, the other speed for servers on your existing Cat. 5 or lower grade trunk in the stand-by mode. In case if one trunk fails, the other network cable. All 4 ports support 10/100Mbps auto-sensing, trunk will provide the backup link. This configuration can be and can be combined into a high-speed trunk transferring data applied for mission-critical situations, or more common at up to 800Mbps full-duplex. applications such as video-conference and IP telephony. Reliable High Performance Priority Queues Support for Quality of Service The card operates at the PCI Bus Master mode with clock With packet prioritization capability, the card allows traffic to speed support at up 33/66MHz. It is equipped with 4 be queued as critical and non-critical, permitting your server to independent MAC controllers, allowing each of the 4 ports to run voice over IP, video-conference and multimedia establish an independent full bandwidth segment with the applications where packets are delivered at best-effort speeds. attached switch. In the unlikely event where one MAC fails, the remaining controllers will continue to operate, Flow Control to Minimize Packet Loss guaranteeing uninterrupted server connection. The card's embedded flow control provides a means to protect against possible data loss during transmission on the network. Load-sharing Aggregated Bandwidth When connected to a Fast Ethernet switch that supports flow You can configure all 4 ports to operate at the load-sharing control, the card receives signals from the switch regarding mode. In this configuration, the ports share the traffic load to buffer overrun during peak usage periods. The card then and from the switch, while the card ensures a balanced load delays transmission until the switch is ready again to accept for each of the ports. This mode guarantees that bottlenecks new data. are eliminated at peak traffic time.
