Q: What chipset does this network card use, and how does it perform?
A: This network card features the Intel 82576 enterprise-grade chipset, designed for servers and data centers. It supports dual Gigabit ports with hardware-level virtualization acceleration, low CPU overhead, and outstanding stability and compatibility.
Q: Which operating systems and virtualization platforms are supported?
A: Broadly 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 excellently in virtualized environments, including advanced features like SR-IOV.
Q: Can a PCIe x1 card be installed in x4/x8/x16 slots?
A: Yes. This card uses a PCIe x1 interface and is backward compatible with x4, x8, and x16 slots. It can be flexibly installed in any PCIe slot on your motherboard without slot size restrictions.
Q: What can I do with the dual ports?
A: The dual ports support a wide range of use cases:
- Link Aggregation: Bond both ports together to achieve up to 2Gbps bandwidth
- Failover: Automatically switch to the other port if one fails, ensuring uninterrupted network connectivity
- WAN/LAN Separation: In soft router setups, use one port for WAN and the other for LAN
- Network Isolation: Connect to different network segments for traffic segmentation
Q: What is the power consumption? Does it run hot?
A: Power consumption is only 2.8W, making it extremely energy-efficient. Heat generation is minimal with no additional cooling required, making it ideal for 24/7 environments such as servers and NAS systems.
Q: Does it support Jumbo Frames?
A: Yes. The Intel 82576 chipset supports Jumbo Frames up to 9KB, improving large file transfer efficiency on local networks — especially beneficial for NAS and storage server applications.
Q: How do I use it in ESXi/Proxmox virtualization environments?
A: The Intel 82576 is an ideal choice for virtualization. It is natively recognized in both ESXi and Proxmox, supports PCIe passthrough to virtual machines, and can be used to create virtual switches shared among multiple VMs. The built-in virtualization acceleration results in minimal performance overhead.
Q: What is included in the package?
A: The package includes:
- 1 × Dual-Port Gigabit Network Card (Intel 82576)
- 1 × Low-Profile Bracket (for compact chassis/servers)
Q: What are the dimensions? What chassis does it fit?
A: The card measures 105×64mm. It comes with a full-height bracket and includes a low-profile bracket. Compatible with standard ATX cases, server chassis, and compact ITX cases (using the low-profile bracket).
Q: What are the main application scenarios?
A: Key use cases include:
- Enterprise Servers/Workstations: Dual-port redundancy or link aggregation
- Virtualization Platforms: ESXi, Proxmox, Hyper-V, etc.
- Soft Routers: pfSense, OPNsense, iKuai, etc.
- NAS Storage: TrueNAS, Unraid, Synology, etc.
- Data Centers: Mission-critical applications requiring reliable network connectivity
