Overview
The PowerEdge XE9640 is Dell's direct-liquid-cooled 2U building block, configured with four NVLink-connected NVIDIA H100 SXM accelerators for maximum GPU density per rack at lower energy overhead. Nexus Compute specifies, integrates, and tests each node and delivers it with Dell ProSupport through authorized channels.
Who This Solution Is For
Business Benefits
Rack density leadership
A 2U four-GPU footprint packs more H100 accelerators per rack than equivalent air-cooled designs.
Lower cooling overhead
Direct liquid cooling cuts fan power and improves PUE while sustaining full GPU clocks under load.
Cluster building block
Standardized 2U nodes simplify linear scale-out into large supercomputing fabrics.
Typical Business Use Cases
Dense HPC GPU clusters
Scientific simulation and modeling
Distributed deep learning
Energy-efficient data center buildouts
Industry Applications
Technical Overview
The XE9640 is Dell's first liquid-cooled four-way GPU platform, fully interconnecting four NVIDIA H100 SXM accelerators over NVLink within a 2U chassis using direct liquid cooling on both GPUs and CPUs. Dual current-generation Intel Xeon Scalable processors, DDR5 memory, and PCIe Gen5 round out a node engineered as a repeatable supercomputing block managed by iDRAC9.

Frequently Asked Questions
Do I need facility liquid cooling for the XE9640?
Yes, the XE9640 uses direct liquid cooling and requires a compatible CDU or facility loop; we help validate flow, temperature, and rack manifold requirements before deployment.
How does the XE9640 compare to the air-cooled XE8640?
Both are four-GPU H100 nodes, but the 2U liquid-cooled XE9640 delivers higher rack density and lower cooling power, while the 4U air-cooled XE8640 suits sites without liquid infrastructure.
Is it suited to multi-node HPC clusters?
It is designed as a standardized building block, so it scales cleanly over NDR InfiniBand into large, dense supercomputing fabrics.
