Silver rack-mount network switch with 32 OSFP ports and rear fan modules

NVIDIA

NVIDIA MQM9700-NS2R 64-port 400Gb/s NDR InfiniBand network switch

SKU CH-QY00-2S1G2 MPN MQM9700-NS2R

Delivers 51.2 Tb/s throughput across 64 NDR InfiniBand ports for exascale HPC and AI clusters

  • 64 ports of 400 Gb/s NDR InfiniBand for massive bandwidth
  • 2 Tb/s aggregated bidirectional throughput for extreme-scale workloads
  • 5 billion packets per second capacity for high packet-rate applications
  • 32 OSFP ports enabling dense 400 Gb/s connectivity
  • Connector-to-power airflow design for efficient rack cooling

64-port 400Gb/s NDR InfiniBand Switch

The NVIDIA MQM9700-NS2R is a managed network switch built on the Quantum-2 platform for high-performance computing and AI clusters. It provides 64 ports of 400Gb/s NDR InfiniBand connectivity with connector-to-power airflow for rack installations.

Sustained throughput and packet capacity

The switch carries 51.2 terabits per second of aggregated bidirectional throughput and processes more than 66.5 billion packets per second. These figures represent continuous fabric capacity rather than a short burst, supporting exascale workloads with ultra-low latency.

Topology scalability and in-network computing limits

Scalability extends across Fat Tree, DragonFly+ and SlimFly topologies with backward compatibility to earlier InfiniBand generations. In-network computing via SHARPv3, GPUDirect RDMA and MPI tag matching offloads collective operations from CPUs, reducing fabric load within the bounds of the NDR standard.

Questions about this item

How much power does the 64-port NDR InfiniBand switch draw when running continuously?

The NVIDIA Quantum-2 QM9700 delivers 51.2 Tb/s of aggregated bidirectional throughput across 64 ports of 400 Gb/s NDR. Power consumption figures are not included in the manufacturer data.

What cables and transceivers must I already have to use the 32 OSFP ports?

The switch provides 32 OSFP cages for 400 Gb/s NDR connectivity. Compatible OSFP transceivers and InfiniBand cables are required for each active port.

Will the MQM9700-NS2R integrate with my existing HDR InfiniBand equipment?

The NVIDIA Quantum-2 switch supports backward compatibility with previous InfiniBand generations across Fat Tree, DragonFly+ and SlimFly topologies.
