Description
The NVIDIA Quantum-2 MQM9790-NS2R InfiniBand switch is part of NVIDIA’s advanced Quantum-2 series, designed to power data-intensive computing environments with unmatched performance and scalability. Featuring 64 non-blocking ports supporting 400Gb/s per port, it delivers an aggregate bidirectional throughput of 51.2 Tb/s and a packet processing capacity exceeding 66.5 billion packets per second. Built for high-performance computing (HPC) and artificial intelligence (AI) workloads, this 1U rackmount switch ensures low-latency, energy-efficient connectivity for next-generation data centers.
The MQM9790-NS2R model provides reverse (connector-to-power) airflow (C2P) and operates as an unmanaged switch, leveraging NVIDIA’s Unified Fabric Manager (UFM®) for advanced external management. It incorporates technologies like NVIDIA SHARPv3, adaptive routing, and RDMA, enabling exceptional network acceleration and real-time data processing. With redundant power supplies, hot-swappable fans, and ENERGY STAR® certification, it delivers enterprise-grade reliability, cooling flexibility, and efficiency.
