Quantum-X800 Switches Overview
Quantum-X800 Switches includes two managed NVIDIA Quantum-X800 InfiniBand systems based on the Quantum-3 switch ASIC. Both deliver XDR connectivity at up to 800Gb/s per port through OSFP interfaces and use air-cooled, standard-depth rack-mount enclosures with C2P airflow. The category spans a dense 4U single-switch platform and a compact 2U dual-switch system, covering different port-density requirements for InfiniBand XDR fabrics. These switches serve large-scale AI and HPC interconnects, including B200 and GB200 cluster environments, with configurations differing mainly in switch count, port density, power-supply count, and aggregate switching capacity.
Q3400-RA is a 4U managed Quantum-3 XDR InfiniBand switch with 144 ports at 800Gb/s presented through 72 OSFP cages. It provides 115.2Tb/s of switching capacity and uses a standard-depth, air-cooled chassis with C2P airflow. The system includes eight AC power supplies, an Intel four-core management CPU, and a rail kit. Its port density supports large InfiniBand compute fabrics connecting GPU clusters in AI and HPC environments.
Q3200-RA is a 2U managed system containing two independent Quantum-3 XDR InfiniBand switches. Each switch provides 36 ports through 18 OSFP cages, giving the enclosure 72 ports across 36 cages, with supported per-port speeds from 40Gb/s to 800Gb/s. The platform supplies two independent 28.8Tb/s switching domains and includes four AC power supplies, an Intel four-core management CPU, standard-depth construction, C2P airflow, and a rail kit. Its dual-switch enclosure supports smaller-scale and mixed-generation InfiniBand fabrics in AI and HPC clusters.
FAQ
- Which model fits a 2U switch allocation?
The Q3200-RA. It uses a 2U chassis and provides 36 XDR ports with 18 OSFP224 ports. The Q3400-RA requires 4U of rack space.
- Which switch supports more than 36 XDR ports?
The Q3400-RA. It provides 144 XDR ports, while the Q3200-RA is specified with 36 XDR ports.
- Do the two switches use different optical module types?
No. Both models are specified for use with 1.6T OSFP224 optical modules. The Q3400-RA has 72 OSFP224 ports, while the Q3200-RA has 18.
- Can these switches carry B300 cluster compute traffic?
Yes. Both Quantum-X800 models are intended to transport compute traffic between B300 servers in AI data center and high-performance computing deployments.
- What airflow direction do these switches use?
Both models use power-to-connector airflow, also identified as C2P. Rack cooling must support airflow from the power-supply side toward the connector side.
