SMUGDESK 6Port 2.5 Gigabit PCIe x4 Network Card

Six 2.5 Gigabit ports on PCIe x4

The SMUGDESK card adds six independent 2500Mbps RJ45 ports to a single PCIe x4 slot. Each port autonegotiates at 2500, 1000 or 100Mbps for flexible multiLAN expansion. The x4 interface supplies enough bandwidth to keep all ports running at full speed simultaneously. It targets builders expanding a soft router, firewall, NAS or monitoring platform.

Suits multiport servers, not single-link upgrades

This adapter fits administrators who need six concurrent 2.5G links for VLANs, WAN aggregation or storage networks. It works with Windows, Windows Server, Linux and VMware ESXi on mainstream motherboards. Buyers needing only one extra 2.5G connection or a 10G uplink should consider a single-port card instead. The bracket occupies one full-height slot.

Six ports share x4 bandwidth headroom

Each port delivers up to 2500Mbps and the x4 link provides aggregate headroom for heavy simultaneous traffic. Under full six-port load the interface sustains wire-speed forwarding without bottlenecks. The design supports long-term continuous operation in industrial or server environments. Performance scales linearly until the PCIe x4 ceiling is reached.
