Add the extra PCIe Gen6x16 connection required for advanced SocketDirect and MultiHost deployments. This NVIDIA auxiliary kit is built around a 250 mm MCIO harness, giving infrastructure teams a purpose-built path for expanding connectivity inside dense server and accelerator platforms. For environments where lane access, signal integrity, and physical routing matter, this kit supports the kind of internal interconnect design that commodity cabling cannot match. It is intended for systems that depend on precise PCIe topology and controlled cable length to maintain clean integration across hosts and devices. Use it when you need to complete a multi-host architecture, add a second high-speed PCIe link, or align a platform build with NVIDIA SocketDirect requirements. The result is a cleaner internal layout and a more reliable foundation for performance-sensitive deployments. This is the kind of accessory that matters when the platform design leaves no room for compromise. It helps preserve the integrity of the PCIe fabric while supporting the deployment standards expected in enterprise and HPC environments.
