What’s Inside the Platform
NVIDIA Quantum-X800 InfiniBand Switches
The NVIDIA Quantum-X800 InfiniBand switch provides 144 ports of 800Gb/s connectivity per port. It includes hardware-based In-Network Computing with SHARP v4, adaptive routing, telemetry-based congestion control, performance isolation capabilities, and a dedicated port supporting the Unified Fabric Manager (UFM). NVIDIA Quantum-X800 switches also add advanced power-efficiency features, including low-power link state and power profiling.
The NVIDIA Quantum-X800 switch provides increased performance and power efficiency to significantly reduce scientific computing, AI workload completion time, and energy costs.
Quantum-X silicon photonics switches further reduce total power consumption and latency by minimizing the distance and number of connections between optics and electronics.
NVIDIA ConnectX-8 SuperNIC
The NVIDIA ConnectX-8 SuperNIC delivers 800Gb/s connectivity with ultra-low latency and supports the latest in advanced In-Network Computing. Based on the ConnectX architecture, it continues to provide accelerated MPI hardware engines, quality of service, adaptive routing, congestion control, and more.
LinkX Cables and Transceivers
The NVIDIA Quantum-X800 platform connectivity options with the NVIDIA LinkX® interconnect portfolio provide the maximum flexibility for building a preferred network topology, using connectorized transceivers with passive fiber cables and linear active copper cables (LACCs).
