Overview
This 5U platform pairs eight NVIDIA L40S 48GB Ada Lovelace GPUs with dual 5th Gen Intel Xeon processors to deliver dense FP8 inference and parameter-efficient fine-tuning in one node. Nexus Compute specifies, integrates, and burn-in tests the complete system, then delivers it warranty-backed through authorized supply channels.
Who This Solution Is For
Business Benefits
Maximum inference density
Eight 48GB GPUs serve large batches and multiple models concurrently from a single 5U chassis.
FP8 cost efficiency
The L40S Transformer Engine delivers high tokens-per-watt for inference without HBM-class capital cost.
Tested before delivery
We validate multi-GPU thermals, firmware, and drivers so the node is production-stable on arrival.
Typical Business Use Cases
Concurrent multi-model LLM inference serving
LoRA and QLoRA fine-tuning of mid-size models
Batch embedding and retrieval pipelines
Mixed AI plus visual-compute workloads
Industry Applications
Technical Overview
Built on the Supermicro SYS-521GE-TNRT 5U dual-root PCIe platform with 13 PCIe Gen5 x16 slots and 32 DDR5 DIMM slots across two Socket E (LGA-4677) CPUs. Eight L40S GPUs connect over PCIe Gen4 x16 within a dual-root topology engineered for balanced GPU-to-CPU bandwidth.

Frequently Asked Questions
How many models can eight L40S GPUs serve at once?
It depends on model size and quantization, but 384GB of aggregate GPU memory comfortably hosts several quantized mid-size LLMs or many smaller models concurrently. We size the configuration to your serving targets during specification.
Is the L40S a good fit for fine-tuning rather than full training?
Yes. The L40S excels at parameter-efficient methods like LoRA and QLoRA and at fine-tuning mid-size models; for large-scale pretraining we would recommend an HBM SXM platform instead.
What facility power and cooling does this 5U node require?
With four 2700W Titanium PSUs it belongs in a data center or properly provisioned server room; we confirm exact power, cooling, and rack requirements before delivery.
