Description

NVIDIA MQM8790-HS2F Quantum HDR InfiniBand Switch, 40 x HDR QSFP56 ports, two power supplies (AC), unmanaged, x86 dual core, standard depth,P2C airflow, rail kit

NVIDIA QM8790 switch systems provide the highest performing fabric solution in a 1U form factor by delivering up to 16Tb/s of non-blocking bandwidth with sub 130ns port-to-port latency. These switches deliver 7.2 billion packets-per-second (Bpps), or 390 million pps per port. These systems are the industry's most cost-effective building blocks for embedded systems and storage with a need for low port density systems. Whether looking at price-to-performance or energy-to-performance, these systems offer superior performance, power and space, reducing capital and operating expenses and providing the best return-on-investment.

Compute Fabric Topology for 140-node DGX SuperPOD

For the complete 140-node DGX SuperPOD, the three-layer switches all use 40-port NVIDIA QM8790 switches. Every 20 DGX A100s in the cluster form a SU, and there are 8 Leaf switches in each SU. The design is rail optimized through both the leaf and spine levels—each InfiniBand HCA on a DGX A100 system is connected to its fat tree topology. This rail-optimized network architecture is of great help in improving the performance of deep learning training.

Questions & Answers
Ask a Question
Q:
Is there a difference in the number of management nodes for switch management/opensm subnet manager on network cards and UFM? Which one is more suitable for customer deployment?
A:
Switch management is suitable for managing up to 2K nodes. UFM and opensm subnet manager on OFED network cards have unlimited management node capabilities but require CPU and hardware processing capabilities on the management node.
Q:
Can HDR switches be backward compatible?
A:
Backward compatibility can be achieved through speed reduction. The 200G HDR port on HDR switches can be reduced to 100G to connect with EDR network cards such as CX6 VPI 100G.
Q:
Do IB switches support Ethernet?
A:
Currently, there are no switches that simultaneously support IB and Ethernet. According to the IB standard, Ethernet data (IPv4, IPv6) can be communicated through the IB network in the form of a tunnel (IPoIB).
