1. Genuine Intel® X550-AT2 Controller Powered by the industry-leading Intel X550-AT2 chipset, this network adapter delivers enterprise-class performance and rock-solid stability. It supports advanced features like SR-IOV, iSCSI, and FCoE, making it the perfect choice for virtualization, high-end servers, and storage networking. 2. Dual 10Gbps Multi-Gigabit Connectivity Equipped with two 10G Base-T RJ45 ports, this card supports NBASE-T technology (10G/5G/2.5G/1G/100M auto-negotiation). It allows you to reach 10Gbps speeds using your existing CAT6A copper cabling, providing a seamless and cost-effective high-bandwidth upgrade. 3. High-Bandwidth PCIe 3.0 x4 Interface Utilizing a PCI Express 3.0 x4 bus interface (physically compatible with x8 and x16 slots), the card ensures maximum throughput for both ports. With a 8GT/s per lane transfer rate, it eliminates performance bottlenecks for data-heavy workflows and high-speed backups. 4. Advanced Thermal Management Features a large-area black aluminum alloy heatsink designed for superior heat dissipation. This ensures the Intel controller stays cool even under sustained full load, preventing thermal throttling and guaranteeing 24/7 stable operation in high-density rackmount servers. 5. Plug-and-Play NAS & Server Ready Engineered for ultimate compatibility. It is a “plug-and-play” solution for Windows Server, Linux, VMware, and Proxmox. It is highly recommended for Synology, QNAP, and Unraid users looking to double their 10GbE network capacity effortlessly. 6. Versatile Mounting Options The package includes both Full-Height and Half-Height (Low Profile) brackets. This flexible design ensures the card fits perfectly into standard 4U chassis as well as compact small-form-factor (SFF) workstations or 2U rack servers.
