Mellanox Quantum-2 NDR400 40-Port InfiniBand Switch

The Mellanox Quantum-2 NDR400 is a high-density spine/leaf InfiniBand switch purpose-built for next-generation AI and high-performance computing (HPC) fabric deployments. With 40 ports of NDR (400 Gbps) connectivity, the MSB8050-HS2R delivers ultra-low latency and deterministic performance required for GPU-accelerated machine learning clusters and large-scale parallel computing environments.

This switch operates as a critical infrastructure component in two-tier or multi-tier Clos fabric topologies, enabling non-blocking bandwidth between compute nodes, storage systems, and accelerators. The architecture supports lossless Ethernet semantics over InfiniBand, ensuring reliable delivery of time-sensitive cluster traffic without application-level retransmission overhead.

Deploy as a spine aggregation layer or leaf-to-spine uplink for modular data center scaling. The MSB8050-HS2R is optimized for sovereign AI infrastructure, research computing centers, and hyperscale GPU training environments where fabric efficiency directly impacts per-dollar compute throughput and model time-to-accuracy.

Ideal for

• GPU cluster interconnect for distributed deep learning model training and inference at scale
• High-performance computing (HPC) fabric for scientific simulation, weather modeling, and computational research
• Real-time analytics and data warehouse query acceleration across disaggregated storage and compute nodes
• Enterprise AI service fabric for multi-tenant machine learning platform infrastructure
• Spine aggregation layer in modular 400G+ data center network architectures
• Low-latency financial modeling and risk simulation compute clusters
