Lenovo ThinkSystem NVIDIA ConnectX-7 NDR 400GbE Adapter | PCIe Gen5 x16

Keep latency-sensitive workloads fed with a Lenovo ThinkSystem adapter built around NVIDIA ConnectX-7 silicon. This 1-port card uses OSFP400 connectivity and a PCIe Gen5 x16 host interface to deliver NDR-class performance for InfiniBand environments where throughput, determinism, and port efficiency matter. The design is aimed at infrastructure teams building AI clusters, HPC fabrics, and storage networks that cannot afford bottlenecks at the server edge. A single high-speed port simplifies cabling and switch planning while preserving the bandwidth required for distributed training, parallel compute, and data movement at scale. PCIe Gen5 x16 provides the host-side bandwidth needed to keep the adapter from becoming the limiting factor, while the OSFP400 interface supports modern high-density fabric design. For organizations standardizing on ThinkSystem platforms, this adapter offers a strong fit when the network must keep pace with accelerated compute rather than trail behind it.
