Open Standards-Based Server Design for Architectural Flexibility
High-Density Servers for the Most
Demanding HPC and AI Workloads

A+ Server 4124GQ-TNMI with optional
1U expansion module

One of the industry’s most advanced and flexible GPU servers,
the A+ Server 4124GQ-TNMI is designed to deliver maximum
acceleration power for large-scale machine learning and HPC
workloads. This modular, open-standards-based platform
supports the family of GPU accelerators selected for the exascale
Frontier supercomputer: the AMD Instinct™ MI200 Series.

Designed for Open Standard GPU Accelerators
The AS -4124GQ-TNMI is part of a family of servers with aconsistent architecture to support a range of GPU accelerator
form factors including Open Compute Project (OCP) Accelerator
Modules (OAM). The server is powered by two 3rd Gen AMD
EPYC™ processors and supports four OAM-form-factor AMD
Instinct™ MI250 GPUs with integrated AMD Infinity Fabric™ Link
technology that provides a total of up to 600 GB/s of aggregate
bandwidth between modules.
To speed communication between the CPU and GPUs, we
designed the server with 32 lanes of PCI-E 4.0 bandwidth toeach of the four GPUs. The server supports 10 hot-swap 2.5"
NVMe U.2 or SAS/SATA drives. Intracluster communication isvery important in HPC workloads, so eight x16 low-profile PCIeslots are provided for networking and cluster interconnects. The
server is powered by four 3000W Titanium-Level power supplies© 2022 Copyright Super Micro Computer, Inc. All rights reserved

Supports 4 OAM-form-factor GPUs for extreme
workload acceleration:• Modular design for flexibility and future-proof
operation• Optimized storage, networking, power, and coolingfor high-performance GPU accelerators• 2-socket design supporting 3rd GenAMD EPYC™ processors• Up to 32 DIMMs for up to 8 TB of DDR4-3200 memory• 10 hot-swap NVMe/SAS/SATA drive bays
• 8 PCI-E 4.0 x16 expansion slots• 2 additional PCIe or AIOM slots with optional
expansion module• Titanium-Level efficiency power supplies
and cooled by five 11.5K RPM fans. Whether you access massive
amounts of data on local storage or over the network, this severputs your data to work seamlessly.
The server’s thermal design gives it headroom to support GPU
accelerators well into the future. The 4U version of the server
supports modules (including the MI250) with up to 560W TDP. An
optional 1U expansion module increases airflow so the server
can accommodate up to 700W per GPU. With the expansion
module, you also gain two open-standard AIOM 3.0 or PCI-E 4.0
x16 slots.

Acceleration for the Exascale Era
The AMD Instinct™ MI200 series accelerators are AMD’s newest
data center GPUs, designed to power discoveries in Exascale
systems, enabling scientists to tackle the most pressing
challenges in both artificial intelligence and high-performancecomputing. The Instinct MI250 makes aquantum leap by supporting HPC codeswith up to 90.5 TFLOPs of FP64 matrix
operations, and supporting AI endeavors
with up to 362.1 TFLOPs of FP16 capacity.
The accelerators house two GPU chips
in each package and support up toSeptember 2022

The AMD ROCm™ platform provides themost popular HPC and AI platforms andlibraries so that you can compile for
ROCm and run on the GPU accelerator of your choice.

Power for HPC and AI Deep LearningThis is the server you need to overcome your most difficult HPC
and AI/ML challenges, including:• Deep-learning workloads: These applications use
process massive amounts of data to train machinelearning models in areas such as video detection andlife sciences, drug discovery, autonomous driving, androbotics.
• High-performance computing: These workloads
use proprietary and open-source platforms to model
geophysical systems, molecular dynamics, physics,viruses, computational chemistry and climate sciences.

The Power of AMD EPYC Processors
Depending on your workload, the CPU may have an importantrole to play in providing highly parallel compute power to speed
time to results. Third-generation AMD EPYC processors arepowered by up to 64 cores per processor and up to 768 MB of L3
cache (in processors with AMD 3D VCache™ technology). Choose
from main-line CPUs having from 8 to 64 cores each, highfrequency processors with excellent per-core performance, andAMD EPYC 7003 Series CPUs with AMD 3D V-Cache technology.
The server’s massive I/O requirements are handled easily by AMD
EPYC processors that provide 128 lanes of PCI-E 4.0 connectivity
for server designs. Clock synchronization between the CPU andmemory clocks speeds transfer of data throughout the system.
AMD EPYC features such as these are consistent across theproduct line, meaning that you can match the processor to yourworkload without concern for whether or not a particular featureis supported.
