🖥️ Servers & Workstations

Ideal for enterprise servers, data centers, and high-performance workstations requiring reliable dual-port connectivity and link aggregation for increased bandwidth.

☁️ Virtualization Platforms

Perfect for VMware ESXi, Proxmox VE, and Hyper-V environments. Intel 82576 chipset provides excellent virtualization support with minimal CPU overhead.

🌐 Soft Routers & NAS

Excellent choice for pfSense, OPNsense, TrueNAS, and other network appliances. Dual ports enable WAN/LAN separation or network redundancy configurations.

Q1: What chipset does this network card use and how is the performance?

This card uses the Intel 82576 enterprise-grade chipset, specifically designed by Intel for servers and data centers. It supports dual gigabit ports with hardware-level virtualization acceleration, low CPU overhead, and excellent stability and compatibility.

Q2: Which operating systems and virtualization platforms are supported?

Widely compatible with Windows, Linux, VMware ESXi, Proxmox VE, TrueNAS, pfSense, OPNsense, and other mainstream systems. The Intel 82576 chipset has comprehensive driver support and performs exceptionally well in virtualization environments, supporting advanced features like SR-IOV.

Q3: Can the PCIe x1 interface be installed in x4/x8/x16 slots?

Yes. This network card uses a PCIe x1 interface and is backward compatible with x4, x8, and x16 slots. You can flexibly install it in any PCIe slot on your motherboard without slot specification restrictions.

Q4: What can dual ports be used for?

Dual ports have a wide range of applications:

• Link Aggregation: Bond two ports to increase bandwidth to 2Gbps
• Failover: Automatically switch to the other port if one fails, ensuring uninterrupted network connectivity
• WAN/LAN Separation: In soft router applications, one port connects to the external network and one to the internal network
• Network Isolation: Connect to different network segments for network traffic distribution

Q5: What is the power consumption? Does it generate much heat?

Power consumption is only 2.8W, very energy efficient. Heat generation is minimal and no additional cooling is required, making it suitable for servers and NAS environments running 24/7.

Q6: Does it support Jumbo Frames?

Yes, the Intel 82576 chipset supports Jumbo Frames (up to 9KB), which can improve large file transfer efficiency on LANs, especially suitable for NAS and storage server applications.

Q7: How to use in ESXi/Proxmox virtualization environments?

The Intel 82576 is an ideal choice for virtualization environments. It can be directly recognized in ESXi and Proxmox, supports passthrough to virtual machines, and can also create virtual switches for multiple VMs to share. The chipset has built-in virtualization acceleration with minimal performance loss.

Q8: What accessories are included in the package?

Package includes:

• 1 × Dual-Port Gigabit Network Card (Intel 82576)
• 1 × Low-Profile Bracket (for small chassis/servers)

Q9: What are the dimensions? What chassis is it suitable for?

Network card dimensions are 105×64mm, comes with a full-height bracket and includes a low-profile bracket. Suitable for standard ATX chassis, server chassis, and small ITX chassis (using low-profile bracket).

Q10: What application scenarios is it suitable for?
