This dual-port QXG-25G2SF-E810 25GbE network expansion card with Intel® Ethernet Controller E810-XXVAM2 supports PCIe Gen4 (backwards compatible with Gen3) and provides up to 25Gbps transfer speeds (10/25Gbps supported). By using SMB Multichannel to aggregate multiplied network connections, you maximize available bandwidth and can achieve up to 50Gb/s for accelerating file sharing and intensive data transfer.

With Network Offload support, the QXG-25G2SF-E810 greatly boosts network efficiency and is ideal for I/O-intensive and latency-sensitive virtualization applications, data centers, and multimedia transmission/real-time video editing.

Compatible with NAS and PC
QNAP Network Expansion Cards support NAS operating systems (QTS and QuTS hero), Windows® 11, Windows Server® and Linux®, allowing you to expand the performance potential of all your networked devices.

Supports Windows and Linux servers/workstations
Besides QNAP devices, the QXG-25G2SF-E810 supports many platforms (including Windows 11, Windows Server® 2022 and Ubuntu® 20.04 LTS) allowing you to attain optimal business performance for a wider range of system applications and services. The higher bandwidth density with reduction in links helps reduce cabling and operational costs.
