NVIDIA ConnectX-8 SuperNIC C8180(900-9X81E-00EX-DT0) 800G AI Networking Adapter for Hyperscale GPU Clusters

The NVIDIA ConnectX-8 SuperNIC (C8180, 900-9X81E-00EX-DT0) represents a generational leap in AI fabric acceleration. Supporting up to 800 gigabits per second (Gb/s) over InfiniBand or Ethernet, this adapter eliminates network bottlenecks in large-scale GPU clusters. With native PCIe Gen6 (up to 48 lanes) and advanced features such as NVIDIA GPUDirect RDMA, SHARP in-network computing, and programmable congestion control, the ConnectX-8 ensures maximum throughput and lowest latency for training, inference, and data-intensive HPC workloads. Its power-efficient design aligns with sustainable AI data center goals while enabling scaling beyond hundreds of thousands of GPUs.

The ConnectX-8 SuperNIC C8180 is purpose-built for next-generation AI fabrics and hyperscale cloud environments:

• AI Factories & Large Language Model Clusters – trillion-parameter model training with 800G front-end and back-end networks.
• High-Performance Computing (HPC) – SHARPv3 in-network reduction accelerates MPI collectives for scientific simulations.
• GPU-Accelerated Cloud Data Centers – multi-tenant isolation, overlay offloads, and advanced QoS.
• Enterprise AI Infrastructure – from inference farms to AI data platforms requiring deterministic low latency.
• Storage & Converged Fabrics – GPUDirect Storage and RoCEv2 for NVMe-oF and distributed file systems.

For NVIDIA ConnectX-8 SuperNIC C8180 (900-9X81E-00EX-DT0) pricing, samples, or integration advice, please contact our networking specialists.

• ☐ Confirm PCIe slot type (PCIe Gen6 x16 or x32? For full 800G host bandwidth, at least PCIe 6.0 x16 recommended)
• ☐ Verify thermal clearance and airflow direction in your chassis (passive heatsink or active fan required?)
• ☐ Choose correct form factor: HHHL / OCP 3.0 / Mezzanine for your server.
• ☐ Select compatible optics/cables: OSFP 800G or QSFP112 2x400G depending on port variant.
• ☐ Ensure target switch supports 800G speed and required protocols (InfiniBand NDR or Ethernet 800G).
• ☐ Check driver & firmware support: MLNX_OFED or NVIDIA DOCA version for your OS.
