## Summary description

The QNAP QXG-100G2SF-E810 is an internal fiber network card designed for high-speed data transfer with a maximum rate of 100000 Mbit/s. It utilizes PCI Express for connectivity, ensuring reliable wired connections for demanding applications. Ideal for data centers and high-performance computing environments.

## Long description

The QNAP QXG-100G2SF-E810 is a dual-port 100 GbE internal fiber network expansion card using the Intel® Ethernet Controller E810 and a PCIe 4.0 host interface. Designed for high-bandwidth environments, it delivers up to 100 Gbps to address performance bottlenecks in virtualization, data centers, and all-flash NVMe storage systems. The card supports iWARP/RDMA and will offer SR-IOV, making it suitable for I/O-intensive and latency-sensitive workloads, and it is compatible with Windows and Linux platforms.
Advantages
The QXG-100G2SF-E810 provides high throughput and low latency over a PCIe 4.0 connection and supports Forward Error Correction (FEC) to mitigate packet loss on long or noisy links. It can connect via QSFP28 or QSFP28-to-(4) SFP28 cabling and supports network redundancy for failover. When paired with high-performance NVMe all-flash storage and appropriate switches, the card helps eliminate network bottlenecks and maximizes storage and server performance.
Suitable for
Data center servers and storage arrays
Virtualization hosts and latency-sensitive workloads
All-flash NVMe systems requiring 100Gbps connectivity
High-performance computing and cloud infrastructure
Key specifications
Model: QNAP QXG-100G2SF-E810
Controller: Intel® Ethernet Controller E810
Ports: Dual QSFP28 (100 GbE)
Interface: PCIe 4.0 (x16 capable)
Maximum data rate: 100000 Mbit/s (100 Gbps)
Connectivity: Wired fiber (QSFP28 / QSFP28 to 4× SFP28)
Supported features: iWARP/RDMA, Forward Error Correction (FEC), SR-IOV (coming soon)

How to use
Install the QXG-100G2SF-E810 into an available PCIe 4.0 x16 (or compatible) slot on a compatible server or workstation. Connect to a QSFP28-capable switch using a QSFP28 cable or use a QSFP28-to-(4) SFP28 breakout cable to link to SFP28 ports. Enable FEC in the switch and host settings if your cabling and topology require error correction. Install the appropriate drivers for your operating system (Windows or Linux) and, if needed, configure iWARP/RDMA and SR-IOV according to your virtualization and network requirements.
Usage recommendations
Use QSFP28 cables and compatible switches to achieve full 100Gbps throughput; enable FEC for long-distance or noisy links and configure network redundancy on the switch for high availability. Pair the card with PCIe Gen4-capable hosts and NVMe all-flash storage, such as QNAP TS-h2490FU, to minimize bottlenecks in I/O-intensive applications.
