Overview
Built on the Supermicro 8U HGX H100 platform, this node pairs eight 80GB SXM5 GPUs over NVSwitch with dual Intel Xeon CPUs for tightly coupled large-model training and high-throughput serving. Nexus Compute specifies, configures, burns in, and warranty-backs every unit, sourced through authorized Supermicro channels and shipped deployment-ready.
Who This Solution Is For
Business Benefits
Maximum GPU bandwidth
NVSwitch links all eight GPUs with 900GB/s all-to-all so large models shard without interconnect bottlenecks.
Tested before it ships
Every node is configured, thermally validated, and burned in so it runs production workloads on arrival.
Authorized-channel assurance
Sourced through authorized Supermicro channels with full manufacturer warranty and firmware provenance.
Typical Business Use Cases
Foundation-model and LLM training
Large-model fine-tuning and RLHF
High-throughput multi-tenant inference
First building block of a scale-out cluster

Frequently Asked Questions
Is this better suited to training or inference?
Its NVSwitch fabric makes it ideal for training and fine-tuning where all eight GPUs must share gradients at full bandwidth, while still excelling at dense multi-model inference.
What facility does an 8U H100 node need?
Plan for a data center or provisioned server room with roughly 10kW per node and adequate airflow; we confirm exact power and cooling during configuration.
Can multiple nodes be clustered?
Yes. We specify InfiniBand adapters so nodes scale into a rail-optimized multi-node cluster as demand grows.
