Description

Overview

The QXG-25G2SF-CX6 features an NVIDIA Mellanox® ConnectX®-6 Lx SmartNIC controller, supports PCIe Gen4 (backwards compatible with Gen3/ Gen2) and provides up to 25 Gbps transfer speeds (supports 10/25Gbps). By using Port Trunking to combine multiple ports, up to 50GbE can be achieved for accelerating file sharing and intensive data transfer. With SR-IOV support, the QXG-25G2SF-CX6 greatly boosts network efficiency and is ideal for I/O-intensive and latency-sensitive virtualization applications and data centers.

High-speed 25GbE Networking
The TS-h3088XU-RP supports 25GbE networking, and can be used with the QXG-25G2SF-CX6 to expand network connectivity. It can also be used with a 25GbE Switch to build a budget-friendly high-speed network environment.

Strengthen Your virtualization Environment with SR-IOV and RoCE
The QXG-25G2SF-CX6 supports SR-IOV, which can allocate bandwidth resources from a physical network card directly to VMs. It ensures reliable VM applications and reduced CPU overheads. The QXG-25G2SF-CX6 also supports RoCE, which can access a network directly in RAM to effectively reduce latency and enhance performance and efficiency for VMware® virtualization environments.

Supports Windows and Linux servers/workstations
Besides QNAP devices, the QXG-25G2SF-CX6 supports many platforms, including Windows® 10, Windows Server®, and Linux® (driver required) which allows you to attain optimal business performance for a wider range of system applications and services. The higher bandwidth density with reduced links helps reduce cabling footprint and operational costs.
