Lenovo ThinkSystem DM Series 40Gb 2-Port Ethernet Card | Fiber Adapter

Increase network capacity without consuming extra chassis space. The Lenovo ThinkSystem DM Series 40 Gb 2-Port Ethernet Card is built for server environments where bandwidth, port density, and predictable integration all matter. With two 40 GbE ports, it gives infrastructure teams more aggregate throughput for storage traffic, virtualization, and clustered applications. This is the kind of adapter that earns its place in a premium server build. Instead of adding more lower-speed interfaces, it concentrates performance into a compact footprint that helps simplify cabling and reduce switch-port pressure. For teams running Lenovo ThinkSystem DM Series systems, it aligns with the platform’s storage and networking demands while supporting the kind of throughput that keeps busy workloads moving. Use it when the network is part of the application path, not just a utility layer. In those environments, a 40 GbE dual-port card can make the difference between a server that keeps up and one that becomes the constraint.
