NETWORKING
Quantum and Spectrum,
End to End
NVIDIA Quantum-X800 InfiniBand and Spectrum-X Ethernet, ConnectX SuperNICs, and BlueField DPUs.
NVIDIA Quantum-X800 InfiniBand
- Quantum Q3400 switch - 144 ports at 800 Gb/s
- SHARP v4 in-network computing
- Adaptive routing, telemetry-based congestion control
NVIDIA Spectrum-X Ethernet
- Spectrum SN5600 switch - 64 ports at 800G, 51.2 Tb/s switching capacity
- Adaptive routing for lossless Ethernet
- Telemetry-based congestion control, noise isolation for multi-tenant workloads
ConnectX SuperNICs
- ConnectX-8 - 800 Gb/s per GPU, InfiniBand XDR or 2×400GbE, PCIe Gen6
- ConnectX-9 - up to 1.6 Tb/s per GPU (Rubin-ready)
BlueField DPUs
Networking, storage, security, and management offloaded from the host CPU, with tenant isolation enforced at the interface.
- BlueField-3 - up to 400 Gb/s
- BlueField-4 (Rubin-ready)
Built and operated
Fabrics built to NVIDIA reference architecture across racks and multi-site domains, with per-site lifecycle control enforced at the BlueField DPU through NVIDIA Infra Controller (NICo), and configuration, telemetry, and link security tracked through FlightDeck.
