BCM5709C Dual Port Gigabit Ethernet PCIe Server Network Card, Low Profile LP PCIe x4 NIC with 2×RJ45 10/100/1000Mbps for Server, NAS, Workstation

This dual-port gigabit PCIe network adapter adopts mature Broadcom BCM5709C controller chip, specially designed for enterprise servers, NAS storage devices and industrial workstations. Equipped with two independent RJ45 gigabit ports, it supports 10/100/1000BASE-T auto-adaptive rate, enabling link aggregation, network redundancy and multi-network segment deployment to meet enterprise high-reliability network demands.

It adopts PCIe 2.0 x4 high-speed bus interface, providing sufficient bandwidth for large file transmission, virtual machine migration and real-time data backup. Integrated TCP Offload Engine (TOE) offloads TCP/IP computing tasks from host CPU, drastically lowering CPU resource consumption during long-time high-traffic network transmission, improving overall server running efficiency.

Comes with standard low-profile (LP) half-height bracket, perfectly compatible with slim 1U rack servers, small chassis workstations and mini storage hosts that cannot fit full-height network cards. The integrated metal heat sink effectively dissipates chip heat to maintain stable long-term 24/7 operation without overheating downtime.

This NIC features ultra-wide system compatibility, fully matching Windows Server series, mainstream Linux distributions, VMware ESXi and other virtualization platforms, plug-and-play with official driver support. It is widely applied in file servers, monitoring storage, virtual host clusters and small enterprise network transformation, a cost-effective enterprise-level gigabit network expansion solution.
