541-1206 - Sun x4 PCI Express Dual Gigabit Ethernet MMF ExpressModule

Description

The Sun x4 541-1206 is a network interface card (NIC) specifically designed to provide high-speed network connectivity for Sun Microsystems servers. It features two Gigabit Ethernet ports, each capable of transmitting data at speeds up to 1 Gbps. This dual-port configuration allows for increased network bandwidth, redundancy, or the ability to connect to separate networks simultaneously, which is crucial for demanding server workloads. The network ports utilize multimode fiber (MMF) optic transceivers, indicated by the MMF designation. Fiber optic connections are preferred in server environments for their ability to transmit data over longer distances and their immunity to electromagnetic interference compared to copper cabling. The use of MMF suggests compatibility with standard multimode fiber infrastructure, typically used for backbone connections or within data centers. This adapter connects to the server's motherboard via a PCI Express (PCIe) bus. The PCIe interface provides a high-bandwidth connection, ensuring that the network adapter can operate at its full Gigabit Ethernet speeds without being limited by the bus. The 'ExpressModule' designation indicates a specific form factor or connector type often found in Sun's modular server designs, suggesting it might be an add-in card designed for a particular Sun server chassis. This card is essential for servers requiring robust, high-performance, and reliable network connectivity.
