10Gbps SFP+ Ethernet Adapter LinksTek X520-DA1

Description

Product Overview

The LinksTek X520-DA1 is a 10Gbps SFP+ Ethernet adapter built around the Intel 82599EN controller, delivering up to 10 GbE or 1 GbE speeds depending on the transceiver used. Housed in a compact 4.53 x 0.73 x 4.72 in metal chassis, it weighs only 3 oz, making it suitable for dense server racks. The PCIe 2.0 x4 interface provides 20 Gbps of bandwidth, ensuring the card can fully utilize the 10 GbE link without bottlenecks. It supports Intel virtualization technologies such as VMDq, SR‑IOV and on‑chip QoS for efficient multi‑tenant environments.

Usage

Designed for data centers, network‑attached storage, high‑performance computing clusters and enterprise workstations, the X520-DA1 excels in environments that demand low latency and high throughput. It is compatible with Windows Server 2012‑2022, Windows 7‑11 and major Linux distributions (RHEL, SLES, Ubuntu) using the IXGBE driver. Whether you are consolidating storage traffic, building a high‑speed LAN, or provisioning virtual machines, this adapter provides the reliable backbone you need.

FAQ

What type of transceiver does the X520-DA1 require?

The adapter uses standard SFP+ transceivers for both 10 GbE and 1 GbE connections. For direct‑attach copper (DAC) cables, it operates at 10 GbE only.

Is the card compatible with virtualized environments?

Yes, it supports Intel virtualization technologies including VMDq, SR‑IOV and on‑chip QoS, making it ideal for VM workloads.

Can I use this card in a PCIe x8 or x16 slot?

Absolutely. The X520-DA1 is backward compatible and will function in PCIe x8 or x16 slots, utilizing only the required x4 lanes.

Do I need additional drivers for Windows 11?

Windows 11 requires the latest IXGBE driver from Intel, which is provided on the LinksTek support page.

What is the warranty period?

LinksTek offers a standard one‑year limited warranty covering manufacturing defects.
