Supermicro 821GE-TNHR-OTO-2-Radium rack server, Dual Xeon 8558H, 1TB DDR5, 960GB SSD, 8 H200 141GB

Supermicro 821GE-TNHR Dual Xeon Server

The Supermicro 821GE-TNHR-OTO-2-Radium is a 2U GPU server system built for large-scale AI training and high-performance computing clusters. It integrates dual Intel Xeon Platinum 8558H processors, each delivering 48 cores and 96 threads at 2.1 GHz with 260 MB cache. Memory capacity reaches 1 TB through 32 DDR5-5600 modules. Eight NVIDIA H200 Tensor Core GPUs provide 141 GB each for massive model workloads.

Suited for AI labs needing maximum GPU density per

Organisations training multi-trillion-parameter models or running inference at scale will use the eight H200 GPUs and 1 TB system memory. Buyers who need more than eight GPUs in a single node, or who require a different GPU architecture, should evaluate alternative platforms. Teams without dedicated 54 V power infrastructure or compliance approval processes will also need a different solution.

Eight H200 GPUs with 141 GB each decide fit

The HGX 8-GPU configuration delivers a fixed 141 GB per accelerator, setting the hard limit for single-model parameter count without pipeline parallelism. Dual Xeon 8558H CPUs supply 96 total threads and 2.1 GHz base frequency for data preprocessing. Dual 3000 W redundant power supplies with 54 V and 12 V outputs power the complete system. A 960 GB 1 DWPD SSD handles boot and local staging.
