About the MQM8790-HS2F HDR InfiniBand Switch
The MQM8790-HS2F HDR InfiniBand Switch delivers 40 ports of 200Gb/s HDR performance, combining exceptional port density with ultra-low latency for demanding HPC and data center environments. Built on the NVIDIA Quantum-2 switch ASIC, this 1U switch provides 16Tb/s of non-blocking aggregate bandwidth with sub-100 nanosecond port-to-port latency using cut-through forwarding, making it ideal for network engineers and AI infrastructure teams deploying large-scale parallel computing fabrics.
The MQM8790-HS2F integrates NVIDIA's SHARP v2 in-network computing capabilities alongside hardware adaptive routing and credit-based flow control to maximize application performance and minimize congestion. Two hot-swappable redundant power supplies ensure high availability with typical power consumption of approximately 460W, while backward compatibility with EDR 100Gb/s and FDR 56Gb/s technologies protects existing infrastructure investments. Management is streamlined through a dedicated 1GbE out-of-band management port and embedded OpenSM subnet manager, with full fabric orchestration via NVIDIA UFM (Unified Fabric Manager). The compact 1U form factor measuring 482 x 600 x 44mm and weighing 13.5kg makes the part number MQM8790-HS2F an efficient choice for space-constrained deployments. IT procurement teams and storage architects will appreciate the flexible airflow options—port-side exhaust or intake—that simplify integration into diverse rack environments.
