Experience a new level of networking performance in your Lenovo ThinkServer with the ThinkServer X520-DA2. This PCIe 10 Gb Ethernet adapter from Intel delivers dual-port SFP+ connectivity designed to accelerate scalable data center workloads, support heavy virtualization, and empower high-speed storage and backup operations. Built for reliability in demanding enterprise environments, the X520-DA2 combines robust hardware, proven drivers, and flexible I/O options to help your server infrastructure scale with confidence. Whether you’re consolidating virtual machines, optimizing traffic between servers and storage, or enabling fast failover in a clustered environment, this adapter is engineered to keep your network moving at the speed of business.

  • Ultra-fast dual-port 10 GbE performance: Each SFP+ port delivers up to 10 gigabits per second of full-duplex bandwidth, enabling high-throughput data transfers, rapid VM live migrations, and ultra-responsive applications. The aggregated capacity supports bandwidth-hungry workloads such as virtualization, database clustering, and high-performance computing without bottlenecks.
  • Intel reliability and enterprise-grade efficiency: Built on Intel’s industry-leading X520/82599 family architecture, the X520-DA2 is known for stable performance, advanced offloads, and broad compatibility with optical transceivers and DAC cables. This reliability translates into lower CPU overhead, predictable latency, and long-term driver support across major operating systems.
  • Advanced virtualization features for modern data centers: The adapter supports key virtualization technologies such as SR-IOV, VMDq, and VMQ, which help isolate and accelerate network traffic for virtual machines. By offloading networking tasks from the CPU, the X520-DA2 improves VM density, reduces host CPU utilization, and enhances overall virtualization performance in private clouds and hypervisor environments.
  • Flexible deployment for diverse networks: Designed to work across Lenovo ThinkServer platforms and other enterprise servers, this card accepts standard 10 GbE SFP+ optics or direct-attach copper (DAC) cables. That flexibility makes it suitable for data centers with evolving fiber infrastructure or mixed environments where different switch topologies are in use.
  • Ease of integration and ongoing manageability: The X520-DA2 is conceived for simple deployment, seamless driver integration, and reliable ongoing operation. It integrates with common server and network management workflows, supports Windows Server and Linux distributions, and benefits from Lenovo and Intel driver updates that keep performance optimized over time.

How to install Lenovo ThinkServer X520-DA2

  • Power down the server, unplug from power, and remove the chassis cover to access the PCIe slots.
  • Identify an available PCIe x4 (or higher) slot that meets the server’s expansion requirements, and prepare the slot by removing the bracket if necessary.
  • Insert the X520-DA2 card firmly into the slot until it is fully seated and secured by the slot bracket.
  • Attach appropriate SFP+ optics or Direct Attach Copper (DAC) cables to each port, selecting optics that match your network switch requirements and distance needs.
  • Replace the chassis cover and power on the server. If required, enter BIOS/UEFI to confirm the adapter is detected and enabled in the PCIe device list.
  • Install and update the proper drivers from Intel or Lenovo for your operating system (Windows Server or Linux). Reboot if prompted and configure basic networking (IP, VLANs, and 10 GbE bonding or teaming as needed) within your OS and any virtualization platform.

Excellent stand
Size: Dual, Style: Glass Free Stand
I love the functionality of this stand! It is very durable and stable. It does not require any form of anchoring to hold monitors. I have two 27 inch monitors attached to my stand with no problems. The stand can be moved in various direction with little effort. Excellent stand if you are looking to enhance your office space.

nice stand, quick easy setup
Size: Quad, Style: Glass Free Stand
nice stand, easy setup, I like that you mount the bracket to the monitor first and then hook it onto the stand. This makes for a quick and easy setup. You do have to wrench down on the screws to keep the monitors from moving. Also you may want to have 4 of the exact same monitors so they all are at same height. I have two that are the same and two others that are different so they dont all mount at same level. I plan on ordering monitors to match.

Fantastic upgrade from my original stand. Base is a little bulky, but stand is versatile and sturdy.
Size: Single, Style: Free-Standing, Size: Single, Style: Free-Standing
Amazing value for this stand. I needed a stand with more degrees of freedom than the original one that came with my monitor, and this stand (which was inexpensive relative to the cost of the monitor) was a great purchase. The base of the stand is a little bulky/high, and the soft material on the bottom of it can rub off very easily if you let the stand catch the back edge of your desk. Otherwise though, the stand is extremely easy to install, and it provides far more degrees of freedom for rotation and translation than the original stand for my monitor. Now my monitor is sitting at a comfortable viewing angle closer to my desk tilted slightly upwards toward me. Just keep in mind that you have to tighten down the height and tilt adjustments (the things that would be affected by gravity). So, if you want to adjust those frequently, this stand might not be a great fit for you. That said, it does provide a hidden but easy-to-access spot to store the keys needed to loosen it up to make those adjustments. So, if you need to make those adjustments, you'll always have quick access to the necessary tools. Highly recommended for its price in particular.
