16× NVIDIA H100 80GB SXM5 (2× HGX H100 8-GPU nodes)
Dual Intel Xeon or AMD EPYC per node
Up to 2TB DDR5 ECC per node
High-throughput NVMe scratch tier (configurable)
Overview
This 16-GPU cluster pairs two HGX H100 8-GPU nodes over a non-blocking NDR InfiniBand fabric, giving teams genuine distributed-training capability without the footprint of a full pod. Nexus Compute specifies, integrates, burns in, and warranty-backs the compute, fabric, and shared storage as one tested system sourced through authorized channels.
Who This Solution Is For
Business Benefits
Real distributed training
A non-blocking NDR fabric lets the two nodes train as one, supporting FSDP and tensor-parallel workloads a single node cannot hold.
Delivered fully tested
We integrate and burn in the full stack so the cluster passes acceptance and runs jobs on arrival, not after weeks of bring-up.
Clean path to a pod
The fabric and storage are specified so you can add nodes toward a 32- or 64-GPU pod on the same architecture.
Typical Business Use Cases
Multi-node fine-tuning of mid-to-large language models
Distributed training pilots (FSDP, DeepSpeed, Megatron)
Shared training capacity for a small research team
Proof-of-concept before scaling to SuperPOD class
Industry Applications
Technical Overview
Two NVIDIA HGX H100 8-GPU SXM5 nodes (16× H100 80GB total) are joined by a rail-optimized NVIDIA Quantum-2 NDR 400Gb/s InfiniBand compute fabric with full NVSwitch inside each node. A high-throughput NVMe scratch tier and Slurm or Kubernetes orchestration complete the system, sized for distributed training from day one.

Frequently Asked Questions
Is 16 GPUs enough to need InfiniBand?
Yes — once you train across two nodes, gradient and activation exchange dominate step time. A non-blocking NDR fabric is what makes 16 GPUs behave like one training resource rather than two separate servers.
Can I start here and grow to a full pod?
We design the fabric and storage so additional HGX nodes drop onto the same rail-optimized topology, letting you scale toward 32 or 64 GPUs without re-architecting.
How is it delivered and supported?
It arrives integrated, burned in, and acceptance-tested, with Nexus-backed hardware warranty and optional NVIDIA AI Enterprise software support.
