GH200 Superchip for AI/HPC workloads

The Supermicro ARS-111GL-NHR-OTO-38 is a 1U rack server built around the NVIDIA GH200 Grace Hopper Superchip. It combines a 72-core Grace CPU with an H100 Tensor Core GPU and 96GB HBM3 video memory. The system targets AI, machine learning and high-performance computing clusters that need unified CPU-GPU memory access.

Unified LPDDR5X memory and E1.S storage limits

The platform provides 480GB of LPDDR5X memory shared between CPU and GPU, removing traditional PCIe bottlenecks for large model workloads. Storage uses 8 front hot-swap E1.S NVMe bays populated with 3.84TB capacity, plus a 960GB M.2 boot drive. Networking is fixed at two 10GbE RJ45 ports and two 25GbE SFP28 ports.

Air-cooled 1U form factor and hot-swap bays

The server fits a standard 1U rack slot and relies on air cooling rated for up to 1000W TDP processors. Eight E1.S bays allow drive replacement without downtime, while two M.2 slots remain available for expansion. Operating temperature range is 10°C to 35°C, so adequate rack airflow must be ensured before deployment.

Questions about this item

How do I decide between the 3.84TB E1.S SSD and the 960GB M.2 SSD for my workload?

The 3.84TB E1.S drive occupies one of the eight front hot-swap bays and is suited for large datasets, while the 960GB M.2 drive uses an internal M-key slot for OS or cache.

What does the 480GB LPDDR5X memory mean for AI training jobs?

The 480GB of LPDDR5X is unified memory shared between the 72-core Grace CPU and the H100 GPU, letting models up to that size run without host-device copies.

What real throughput do the 10GbE and 25GbE ports deliver?

The Intel X550 dual-port 10GbE card runs at PCIe 3.0 x4, and the NVIDIA dual-port 25GbE adapter uses SFP28; each port caps at its rated line speed.
