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.

Connectivity Solutions
Compute Fabric Topology for 140-node DGX SuperPOD

The 140-node DGX SuperPOD uses 40-port NVIDIA QM8790 switches for all three layers. Each cluster SU consists of 20 DGX A100s, with 8 Leaf switches per SU. With each DGX A100 InfiniBand HCA connected to its fat tree topology, the rail-optimized design at both leaf and spine levels significantly boosts deep learning training performance.

Questions & Answers
Ask a Question
Q:
Is there a difference in the number of management nodes between the switch management function, the opensm subnet manager of the network card, and UFM? Which option is more suitable for customers during deployment?
A:
The management switch is suitable for managing up to 2,000 nodes, while UFM and OFED's openSM node management capabilities are unlimited, depending on the CPU and hardware processing capacity of the management nodes.
Q:
Can the HDR switch support downward compatibility?
A:
Yes, it can achieve downward compatibility by reducing the speed. The 200G HDR ports on the HDR switch can be downshifted to 100G to connect to the EDR network card CX6 VPI 100G.
Q:
Does the IB switch support Ethernet?
A:
Currently, there are no switches that simultaneously support IB and Ethernet. According to IB standards, Ethernet data (IPv4, IPv6) can communicate over the IB network in a tunneled format (IPoIB).
