Part Number: C8180 (900-9X81E-00EX-ST0)

Brand: NVIDIA/Mellanox

Adapter Card : NVIDIA/Mellanox Original C8180 ConnectX-8 InfiniBand & Ethernet SuperNIC, Socket-Direct XDR 800Gb/s PAM4 200G/Lane, Single-Port OSFP, PCIe 6.0 x16, HHHL, Tall Bracket

The NVIDIA/Mellanox C8180 ConnectX-8 SuperNIC is engineered to supercharge hyperscale AI computing workloads, AI factories, and next-generation cloud data centers. Delivering dual-protocol support for both InfiniBand XDR and high-speed Ethernet at up to 800Gb/s (PAM4 200G/lane), this single-port OSFP network adapter optimizes bandwidth, lowers latency, and maximizes cluster interconnect efficiency.

Built with native PCIe 6.0 x16 host connectivity and an integrated PCIe Gen6 switching fabric, the ConnectX-8 SuperNIC eliminates external PCIe switch chips to simplify server architecture while unlocking massive system throughput. It features an advanced hardware Data Path Accelerator (DPA) powered by a RISC-V event processor, along with SHARP (Scalable Hierarchical Aggregation and Reduction Protocol) in-network computing to offload collective operations (such as All-Reduce and All-to-All) directly at the NIC level.

Key Features

• 800Gb/s High-Bandwidth Architecture: Supports XDR 800Gb/s InfiniBand and 800G/400G/200G Ethernet protocols over a single OSFP interface.
• Native PCIe 6.0 x16 & On-Board Switching: Integrates native PCIe Gen6 switching and Multi-Host/Socket-Direct architecture for direct CPU/GPU access without external PCIe switches.
• DPA & RISC-V Hardware Acceleration: Features a dedicated Data Path Accelerator (DPA) and Packet Stream Processor (PSA) for programmable packet parsing, flow control, and SDN offloads.
• In-Network Computing (SHARP v3): Offloads AI compute aggregations directly to the network, drastically accelerating multi-GPU and multi-node AI model training.
• Advanced Congestion Control: Telemetry-based adaptive routing and congestion management reduce tail latency and stabilize large-scale GPU clusters.
• Hardware Security: Integrated encryption engines and secure boot protection ensure end-to-end data safety in multi-tenant environments.
