Description
NVIDIA ConnectX-8 SuperNIC C8180-DT0 800G High-Density AI Fabric
Model: 900-9X81E-00EX-DT0 | Multi-Host | High Density | AI Factory Optimized
The DT0 (Density / Hyperscale) variant is engineered for AI factories operating 10,000+ GPUs. Features NVIDIA Multi-Host technology (up to 4 hosts per adapter), advanced power management (under 28W typical), and telemetry-based congestion control for predictable large-scale performance.
Product Overview - Hyperscale Edition
NVIDIA ConnectX-8 SuperNIC C8180-DT (900-9X81E-00EX-DT0) is purpose-built for hyperscale AI operators. Unlike standard enterprise SKUs, the DT0 variant includes Multi-Host PCIe capabilities allowing a single adapter to serve up to four independent host processors — reducing NIC count per rack and lowering total cost of ownership. Enhanced telemetry and programmable congestion control ensure consistent tail latency across thousands of GPU nodes.
Hyperscale Advantages
  • 4:1 Multi-Host consolidation (4 hosts per NIC)
  • <28W typical power at full 800G load
  • Advanced telemetry: per-flow latency, queue depth, ECN marking
  • Adaptive routing support for load-balanced fabrics
  • SHARPv3 in-network reduction for collective operations
Scalability Metrics
  • Supports AI clusters of 100,000+ GPUs
  • 16 million I/O channels per adapter
  • Up to 8 logical ports via splitter cables
  • Zero packet loss at line rate (PFC + ECN)
  • RDMA over Converged Ethernet v2 (RoCEv2)
Multi-Host Architecture
Configuration Hosts Supported Total Bandwidth per Host Use Case
1 Host 1 800Gb/s Maximum single-host throughput
2 Hosts 2 400Gb/s each Balanced dual-node density
4 Hosts 4 200Gb/s each Maximum rack density
Target Deployments - Hyperscale AI Factories
  • Large language model training clusters (GPT-5 scale)
  • Autonomous vehicle training infrastructure
  • Cloud provider GPU-as-a-service platforms
  • National supercomputing centers
  • AI semiconductor design simulation farms
Power & Thermal Optimization
The DT0 variant features enhanced power gating and dynamic voltage scaling, achieving 25-28W typical at 800Gb/s line rate — 15% more efficient than previous generation. Passive cooling sufficient for 1U servers with adequate front-to-back airflow.
