Enterprise-Level Network Performance

Experience Next-Generation Networking with QXG-25G2SF-E810

The QNAP QXG-25G2SF-E810 is a dual-port 25GbE network expansion card that brings enterprise-level network performance to your NAS and PC. Equipped with the Intel® Ethernet Controller E810-XXVAM2 and supporting PCIe Gen4 (backward compatible with Gen3), this card is designed to handle intensive data transfer and high-speed file sharing, making it ideal for data centers, virtualization applications, and real-time video editing.

Key Features

High-Speed 25GbE Connectivity

• Delivers up to 25Gbps transfer speeds (10/25Gbps supported), enabling ultra-fast network performance.

Bandwidth Aggregation with SMB Multichannel

• By aggregating multiple network connections, achieve up to 50Gb/s bandwidth for accelerated file sharing and data transfer.

Network Offload Support

• Enhances network efficiency, particularly beneficial for I/O-intensive and latency-sensitive applications.

Broad Compatibility

• Supports NAS operating systems (QTS and QuTS hero), Windows® 11, Windows Server®, and Linux®, offering versatile performance expansion for various networked devices.

Build High-Speed 25GbE Networks

• Ideal for creating ultra-high-speed and scalable network environments when paired with QNAP NAS and 25GbE network switches.

Forward Error Correction (FEC) for Reliable Data Transfer

• Supports FEC to detect and recover lost data, ensuring reliable transmission over long distances and noisy channels. Offers three FEC modes for different latency and distance requirements.

FEC Modes for Different Network Environments

• NO FEC: Lowest latency, suitable for shortest distances.
• BASE-R FEC (Firecode): Approximately 80ns latency, ideal for middle distances.
• RS-FEC (Reed Solomon): Approximately 260ns latency, best for the longest distances.

Notes for Optimal Setup

1. Matching FEC Modes: Ensure both the source and receiver use the same FEC mode for compatibility.
2. Switch Compatibility: Check if your switch's firmware supports FEC. If not, disable the FEC function on the NIC through the NAS or computer operating system.

Summary

The QNAP QXG-25G2SF-E810 network expansion card is a powerful solution for users seeking to upgrade their network infrastructure to 25GbE. Its combination of high-speed connectivity, bandwidth aggregation, and FEC support makes it an ideal choice for demanding network environments, ensuring fast, efficient, and reliable data transfer.
