10Gb PCI-E NIC Dual SFP+ Network Card - Server Virtualization Ready

In this review the 10Gb PCI-E NIC dual SFP+ network card is judged on raw throughput, server compatibility and real-world installation. It is best suited for users who need reliable 10Gb/1Gb connectivity on commodity servers or workstations and want the stability of an Intel X710 chipset. The single biggest reason to consider this card is its X710 controller, which delivers consistent performance for virtualization and multi-core systems while supporting FCoE for converged storage and network deployments.

Key Features

• Intel X710 chipset: provides stable, enterprise-grade Ethernet offload and broad driver support for Windows, Linux and VMware environments.
• Dual SFP+ ports: allow flexible use of 10GBASE-SR, 10GBASE-LR transceivers or SFP+ DAC/AOC cabling for short or long runs.
• PCIe v3.0 x8/x16 interface: delivers full 10Gb throughput with modern motherboards and supports installation in either x8 or x16 slots.
• FCoE support: enables Fibre Channel over Ethernet to simplify storage and network convergence for servers that require it.
• Standard and low-profile brackets: included brackets make the card easy to mount in a variety of desktop and rack server chassis.

Who It's For

This card is aimed at IT professionals, home lab builders and small business servers that need dependable 10Gb or 1Gb NIC connections, especially where virtualization or multi-core processing is in use. The included Linux, Windows and VMware driver support makes it a practical choice for mixed OS environments and for those who run virtual machines or storage over Ethernet.

Users who need multi-speed auto-negotiation to 2.5Gb or 5Gb or who expect native Wi-Fi features should look elsewhere. Also, those without available PCIe x8/x16 slots or who require built-in RJ45 copper ports will need a different adapter.

Pros & Cons

Pros

• Enterprise-grade Intel X710 controller delivers consistent performance and wide OS support.
• Dual SFP+ ports provide cabling flexibility with SR/LR transceivers or DAC/AOC cables.
• Includes both standard and low-profile brackets for versatile chassis installation.

Cons

• Does not support 2.5Gb or 5Gb rates, so intermediate speeds are unavailable.

Specifications

Our Verdict

The dual SFP+ 10Gb PCI-E NIC is a solid, cost-effective choice for anyone who needs reliable 10Gb or 1Gb connectivity with broad OS and virtualization support. Its Intel X710 foundation and FCoE capability make it particularly useful in small server or home lab setups where converged networking is desired, provided the lack of 2.5G/5G support is acceptable.

Frequently Asked Questions

Will this card work in a standard PCIe x16 slot?
Yes, it is compatible with PCIe v3.0 x8 or x16 slots and will operate at full performance when installed in either.

Can I use RJ45 copper cables with this card?
No, this card uses SFP+ ports and requires appropriate transceivers or DAC/AOC cabling for copper or fiber connections.

Does it support intermediate 2.5Gb or 5Gb Ethernet rates?
No, the supported Ethernet speeds are 10Gb and 1Gb only; 2.5Gb and 5Gb are not supported.
