Lenovo ThinkStation NVLink Bridge, 2-slot

The Lenovo ThinkStation NVLink Bridge (4XH1L18997) is a 2-way graphics card bridge for ThinkStation workstations. It physically connects two compatible professional graphics cards via the NVIDIA NVLink interface. By providing a high-bandwidth connection, the bridge allows software to pool memory and scale performance across both GPUs. It is configured for 2-slot spacing, ensuring the bridge aligns correctly with cards installed in adjacent PCIe slots. It is required for GPU-accelerated rendering, simulation, and compute tasks, allowing data to be transferred directly between the cards rather than via the system bus.

The unit has a black housing and features two NVLink connectors. It weighs 460 grams and has a 5.44 mm profile to avoid interfering with other internal components. It is designed for Lenovo ThinkStation chassis that support dual-GPU configurations. The bridge accommodates a 50.3 mm spacing, which is standard for professional multi-GPU setups. It complies with several international standards, including CE, FCC, VCCI, and RCM. The package includes one bridge and the necessary documentation. Users must ensure that both the workstation motherboard and the graphics card models support NVLink technology before installation.
