MTMK0011, Mellanox ConnectX-6 Extension Kit, PCIe Gen3 x16/2x150mm I-PEX/Auxiliary Card

The Mellanox NVIDIA Mellanox MTMK0011 is a specialized extension kit / accessory designed to expand PCI Express connectivity for Mellanox ConnectX-6 series adapters in modern data center and enterprise server environments. This kit adds an auxiliary PCI Express Gen3 x16 connection path, allowing system designers and integrators to unlock more bandwidth or flexible board layout without changing the main server motherboard. The NVIDIA Mellanox MTMK0011 includes a dedicated PCIe Gen3 x16 auxiliary card and two 150 mm I-PEX high‑speed cables, engineered to carry reliable PCIe Gen3 signals between the ConnectX-6 adapter and the auxiliary slot. By using the PCI Express Gen3 x16 (auxiliary connection) interface standard, it helps maintain consistent performance and low latency, which is important for workloads such as virtualization, storage, and AI clusters in Asia, Europe, Africa, and North America. This Mellanox accessory is suitable for distributors who need a complete portfolio for ConnectX-6 deployments, for small and medium system integrators looking to optimize server PCIe routing, and for end users who want a validated way to add an extra PCIe Gen3 x16 connection without complex custom cabling. The compact 150 mm I-PEX high‑speed cables reduce signal loss and simplify installation inside dense rackmount servers. With its clear kit contents and focused application—providing an additional PCIe Gen3 x16 connection for supported ConnectX-6 adapters—the NVIDIA Mellanox MTMK0011 offers a simple, robust option to scale network adapter connectivity while keeping deployment predictable and easy to support across different regional data center standards.
