About the NVIDIA Quantum-X800 InfiniBand Switch
Delivering 102.4 Tb/s aggregate switching capacity with line-rate performance across all 64 ports, the NVIDIA Quantum-X800 InfiniBand Switch (QM9790-HS2F) is engineered for next-generation high-performance computing and AI infrastructure clusters. This 1U switch harnesses NDR800 InfiniBand technology to provide 800 Gb/s per port, eliminating bottlenecks in latency-sensitive workloads where microseconds matter and fabric efficiency directly impacts ROI.
Purpose-built for network architects and AI infrastructure teams managing large-scale distributed systems, the QM9790-HS2F combines NVIDIA's proven Quantum switching architecture with advanced congestion control and in-network computing capabilities. The switch integrates NVIDIA SHARP v4 (Scalable Hierarchical Aggregation and Reduction Protocol) for collective operations acceleration, adaptive and static routing options, and self-healing fabric support to maximize uptime and performance. Redundant hot-swappable power supplies ensure continuous operation, while front-to-rear airflow (HS suffix) optimizes thermal design in standard rack deployments. Management is streamlined through NVIDIA UFM (Unified Fabric Manager) compatibility and an out-of-band Ethernet management port, enabling seamless integration into existing monitoring ecosystems. The switch runs on Linux via the MLNX_OFED driver stack and complies with the InfiniBand Architecture Specification (IBTA) and NDR800 standards, guaranteeing interoperability across certified hardware partners.

Frequently Asked Questions about NVIDIA Quantum-X800 InfiniBand Switch
Does the NVIDIA Quantum-X800 InfiniBand Switch support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations in advance, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises later.
Is the support global?
Yes — manufacturer hardware support is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
