Lenovo ThinkSystem NVIDIA ConnectX-7 NDR 400GbE 1-Port | PCIe Gen5

Keep distributed workloads moving with a 400 GbE adapter designed for dense, high-bandwidth infrastructure. The ThinkSystem NVIDIA ConnectX-7 NDR OSFP400 1-port InfiniBand adapter pairs a single high-speed port with PCIe Gen5 x16 host connectivity, giving Lenovo ThinkSystem platforms the bandwidth headroom needed for AI training, HPC fabrics, and storage-heavy clusters. This adapter is built for environments where oversubscription is not acceptable and every microsecond matters. The OSFP400 interface supports modern high-speed cabling strategies, while the ConnectX-7 platform is engineered for demanding network paths that carry large datasets between compute nodes, accelerators, and shared storage. For teams standardizing on Lenovo servers, it offers a clean fit for premium fabric builds without adding unnecessary port complexity. Choose this model when you need fewer adapters, fewer cables, and more throughput per slot. It is a strong fit for infrastructure that must sustain predictable performance under sustained load, especially where rack space, airflow, and PCIe lane efficiency are part of the design brief.
