2PORT SFP28 25GBE NETWORK EXPANSION CARD LP PCIE GEN4X8 PCIE

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.

Ensure reliable data transfer with Forward Error Correction (FEC)

The QXG-25G2SF-CX6 supports FEC to overcome packet loss - a potentially common occurrence in fast, long-distance networks. FEC helps the receiving side detect and recover lost data to correct bit errors, thus ensuring reliable data transmission over "noisy" communication channels. With three FEC modes, you can use a suitable cable and switch to build an optimal network environment.

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.
