Product Description
NVIDIA Quantum-2 MQM9790-NS2F NDR Switch
A 1U externally managed NDR InfiniBand switch delivering 64 ports of 400Gb/s InfiniBand over 32 OSFP connectors with 51.2 Tb/s aggregated bidirectional throughput and P2C airflow.
Product Overview
The NVIDIA Quantum-2 based QM9790-NS2F is a 1U fixed-configuration InfiniBand switch designed for extreme-scale HPC and AI systems. It provides 64 ports of NDR 400Gb/s InfiniBand in a standard 1U chassis, using 32 octal small form-factor pluggable (OSFP) connectors with an aggregated bidirectional throughput of 51.2 Tb/s and more than 66.5 billion packets per second (BPPS) capacity.
This externally managed variant is designed to work with the NVIDIA Unified Fabric Manager (UFM) platform and supports RDMA, adaptive routing, and NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP), including third-generation SHARPv3.
Key Features
- 64 ports of 400Gb/s InfiniBand over 32 OSFP connectors, non-blocking
- 51.2 Tb/s aggregate bidirectional throughput with more than 66.5 BPPS capacity
- Externally managed design for use with NVIDIA UFM feature sets
- P2C forward airflow for compatibility with standard front-to-rear rack cooling
- Port-split technology support for double-density radix at 200Gb/s, up to 128 ports
- SHARPv3 in-network computing with up to 32X higher AI acceleration power
- Self-healing network capabilities, QoS, enhanced VL mapping, and congestion control
- 1+1 redundant hot-swappable power supplies with 200-240Vac input
- Hot-swappable fan unit with front-to-rear or rear-to-front cooling options
- 1U rack mount with compact depth of 26.0 in (660.4 mm)
- Backwards compatible with previous InfiniBand generations
