Dual Intel Xeon or AMD EPYC per node
High-throughput parallel filesystem, GPUDirect Storage
Overview
This 256-GPU SuperCluster packs thirty-two liquid-cooled 4U HGX H100 nodes into five racks using direct-to-chip cold plates and in-rack coolant distribution. Nexus Compute specifies, integrates, and acceptance-tests the compute, NDR fabric, CDUs, and parallel storage as one warranty-backed, plug-and-play system from authorized channels.
Who This Solution Is For
Business Benefits
Density without the heat ceiling
Direct-to-chip liquid cooling lets eight 4U nodes share a rack, fitting 256 GPUs in five racks where air cooling cannot.
Lower operating power
Rack-scale liquid cooling cuts facility cooling overhead substantially, improving PUE and total cost over a sustained-use fleet.
Plug-and-play delivery
We integrate compute, CDUs, fabric, and storage and validate them as a unit, so the SuperCluster commissions quickly on site.
Typical Business Use Cases
Large sustained foundation-model training fleets
High-density GPU capacity in constrained facilities
Energy-efficient AI factories targeting low PUE
Multi-tenant training and inference at rack scale
Industry Applications
Technical Overview
Thirty-two liquid-cooled Supermicro-class 4U HGX H100 8-GPU nodes (256× H100 80GB) deploy across four compute racks and one switching rack, with CPUs and GPUs on cold plates and a 4U Coolant Distribution Unit per rack feeding a facility loop. A non-blocking NVIDIA Quantum-2 NDR 400Gb/s InfiniBand fabric (QM9700 spine/leaf) and parallel storage unify the 256 GPUs as one system.

Frequently Asked Questions
What does my facility need for liquid cooling?
You need a facility water loop or dry cooler the rack CDUs can reject heat to; we provide the flow, temperature, and connection requirements and coordinate the secondary-loop design as part of delivery.
How much does liquid cooling actually save?
Rack-scale direct-to-chip cooling can cut data-center cooling power meaningfully versus equivalent air-cooled density, which compounds into real operating savings across a 256-GPU fleet running continuously.
Is it truly plug-and-play?
We pre-integrate and validate compute, CDUs, fabric, and storage as a unit, so on-site work is connection and commissioning rather than ground-up assembly and bring-up.
