2PORT SFP28 25GBE NETWORK EXPANSION CARD LP PCIE GEN4X8 PCIE (QXG25G2SFCX6)

This item is brand-new, factory sealed.

QXG-25G2SF-CX6

Supports SR-IOV and RoCE for Improved Network and VMware Virtualization Environments

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. 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.

Note:

1. SR-IOV is supported by specific QNAP NAS models and should work with SR-IOV compatible adapters.

2. Both the NAS that installs the QXG-25G2SF-CX6 and the receiving-end devices must support RoCE. If the receiving devices do not support RoCE, it will use TCP/IP.Controller
