Product Description
NVIDIA ConnectX-8 SuperNIC C8180(900-9X81E-00EX-ST0) Network Card
1. Product Overview
The NVIDIA ConnectX-8 SuperNIC (Model: C8180) is an ultra-high-performance network interface card designed for next-generation AI and hyperscale data centers. Supporting both InfiniBand and Ethernet protocols at speeds up to 800 Gb/s, this NIC card delivers exceptional bandwidth, low latency, and advanced offload capabilities for AI training, cloud networking, and high-performance computing.
2. Key Characteristics
- Dual-protocol support: InfiniBand and Ethernet up to 800 Gb/s
- PCIe Gen6 host interface with up to 48 lanes
- Advanced RDMA, RoCEv2, and GPUDirect® support
- Hardware-offload for AI, security, and networking protocols
- Multi-host support and scalable I/O performance
3. Core Technologies
The ConnectX-8 SuperNIC leverages cutting-edge technologies including:
- InfiniBand (IBTA v1.7) and Ethernet (IEEE compliant)
- NVIDIA SHARP™ for in-network computing
- Hardware-accelerated IPsec, MACsec, and TLS crypto
- Precision Timing Protocol (PTP) and SyncE
- SR-IOV and ASAP² for virtualized environments
4. Working Principle
The ConnectX-8 SuperNIC operates by offloading network, storage, and security processing from the CPU directly to the NIC hardware. It uses RDMA and RoCE to enable direct memory access between servers and GPUs, reducing latency and increasing throughput. The card also supports advanced congestion control and packet pacing to maintain consistent performance under heavy load.
5. Applications
- AI and machine learning training clusters
- High-performance computing (HPC) environments
- Cloud data centers and hyperscale infrastructures
- Storage area networks (SAN) and data processing units (DPU)
- Telecommunications and edge computing deployments
