Lenovo ConnectX-4 LX ML2 1x25GbE SFP28 Ethernet Adapter

The Lenovo 00MN990 is a ConnectX-4 LX ML2 Ethernet adapter that gives a server a single 25 Gigabit Ethernet link through an SFP28 port. It is purpose-built for Lenovo systems that accept the mezzanine LAN-on-Motherboard form factor, so it installs neatly without occupying a full PCIe slot or adding extra cabling complexity.

With a sustained data rate of up to 25 Gbps, the adapter moves large volumes of traffic quickly, making it a strong match for cloud infrastructure, Big Data analytics, and modern web services that place heavy demands on bandwidth. Workloads such as distributed databases, virtual machine migration, and high-performance computing clusters benefit from the low latency and high throughput that the card delivers.

Because the adapter weighs only 0.54 pounds, it introduces minimal additional load on the server chassis. This lean profile helps maintain efficient airflow and contributes to reliable thermal management in dense rack environments. Enterprises that are expanding or refreshing network capacity can use the Lenovo 00MN990 to scale performance while leaving space for additional storage or compute upgrades.

Data center administrators will appreciate the straightforward integration. The ML2 design allows firmware and management tools already in the Lenovo ecosystem to recognize and configure the card quickly, reducing deployment time and helping teams keep critical services online with minimal interruption.
