Overview
This 4U liquid-cooled node pairs the NVIDIA HGX B200 8-GPU baseboard with dual Intel Xeon processors and direct-to-chip cold plates that capture the bulk of system heat for dense, quiet, rack-efficient deployment. Nexus Compute specifies, configures, burns in, and warranty-backs each system, sourced through authorized channels and validated against your training workload before it ships.
Who This Solution Is For
Business Benefits
Maximum density per rack
Direct-to-chip liquid cooling fits eight 1000W-class Blackwell GPUs into 4U so more compute lands in every rack.
Lower cooling overhead
Capturing most heat at the cold plate cuts data-center cooling energy versus equivalent air-cooled deployments.
Tested before delivery
Each node is configured, thermally validated, and burned in so it reaches production stability on arrival.
Typical Business Use Cases
Foundation and large language model pretraining
Distributed multi-node training over NVLink and InfiniBand
High-density liquid-cooled rack build-outs
Mixed-precision FP8 and FP4 training pipelines
Industry Applications
Technical Overview
Built on the NVIDIA HGX B200 8-GPU platform with fifth-generation NVLink and NVSwitch delivering 1.8TB/s of all-to-all GPU bandwidth, and direct-to-chip liquid cooling rated for the full 1000W per-GPU envelope. A 1:1 GPU-to-NIC ratio with ConnectX-7 or BlueField-3 enables non-blocking scale-out across an InfiniBand or Ethernet fabric.

Frequently Asked Questions
Do I need facility liquid cooling to deploy this?
Yes. This node uses direct-to-chip cold plates and requires a rack manifold or CDU loop. We confirm coolant, flow, and rack readiness during specification and can advise where a CDU is needed.
How does the 4U liquid node compare to the 10U air-cooled B200?
The liquid 4U packs more GPUs per rack and lowers cooling energy, but requires a liquid loop. The 10U air-cooled variant drops into standard racks without plumbing. We match the choice to your facility.
Is this a training or inference platform?
It excels at large-model training thanks to full NVSwitch bandwidth, and also serves high-throughput inference. We size memory, storage, and fabric to your dominant workload.
