4x NVIDIA A100 PCIe 80GB HBM2e
Dual Intel Xeon Platinum 8380 (40-core)
512GB–1TB DDR4-3200 ECC
2x 1.92TB NVMe boot + hot-swap NVMe bays
Overview
This 4U air-cooled platform pairs four A100 80GB PCIe accelerators with NVLink bridges for high-bandwidth GPU pairs in a standard rack. Nexus Compute configures, validates, and warranty-backs each unit through authorized distribution for teams scaling beyond a workstation.
Who This Solution Is For
Business Benefits
80GB memory per GPU
HBM2e capacity holds larger batches and longer context than 40GB cards for fine-tuning workloads.
Standard-rack friendly
Air-cooled 4U design deploys in conventional server rooms without liquid-cooling infrastructure.
Paired NVLink bandwidth
NVLink bridges accelerate GPU-to-GPU transfers within pairs for data-parallel training.
Typical Business Use Cases
Mid-size model fine-tuning and LoRA workloads
Shared multi-user research compute
On-premises AI pilots and proofs of concept
Batch inference and embedding generation
Industry Applications

Frequently Asked Questions
Why choose PCIe A100 over SXM?
PCIe A100s deploy in standard air-cooled racks with lower power and integration cost; SXM/HGX wins when you need all-eight NVSwitch bandwidth for large-scale training.
Does the 80GB memory matter for fine-tuning?
Yes. The larger HBM2e capacity holds bigger batches and longer sequences, reducing gradient accumulation steps and improving throughput on fine-tuning jobs.
What facility does it need?
It runs in a properly ventilated server room with adequate power; we confirm exact power and cooling requirements during specification.
