Overview
The PowerEdge XE8640 is a 4U air-cooled server configured with four NVLink-connected NVIDIA HGX H100 SXM5 accelerators, designed for sites that need four-GPU AI and HPC performance without facility liquid cooling. Nexus Compute specifies, integrates, and tests each system, delivered with Dell ProSupport through authorized channels.
Who This Solution Is For
Business Benefits
No liquid infrastructure
Liquid-assisted air cooling lets the node deploy in standard data center rows without a facility water loop.
Balanced AI and HPC
Four NVLinked H100 GPUs handle both deep learning and double-precision simulation in one platform.
Deployment-ready
Systems arrive integrated, thermally validated, and firmware-baselined with Dell ProSupport coverage.
Typical Business Use Cases
HPC modeling and simulation
Mid-scale model training and fine-tuning
Mixed AI and scientific computing
Departmental GPU clusters
Industry Applications
Technical Overview
The XE8640 fully interconnects four NVIDIA HGX H100 SXM5 accelerators over NVLink in a 4U chassis cooled by liquid-assisted air cooling, avoiding any facility liquid requirement. Dual current-generation Intel Xeon Scalable CPUs, DDR5 memory, and PCIe Gen5 expansion drive the GPUs, with iDRAC9 providing enterprise management.

Frequently Asked Questions
Can the XE8640 run in a standard air-cooled data center?
Yes, its liquid-assisted air cooling needs no facility water loop, so it deploys in conventional racks while still supporting four 700W H100 GPUs.
Is four GPUs enough for my training workload?
A four-GPU NVLink node fine-tunes and trains mid-sized models efficiently; for frontier-scale pretraining we would point you to the eight-GPU XE9680.
What deployment support is included?
Nexus Compute integrates and burn-in tests each unit and coordinates Dell ProSupport, so the server is production-ready on delivery.
