Industry Applications
Technical Overview
The SR670 V2 SXM model integrates the NVIDIA HGX A100 4-GPU baseboard with NVLink and NVSwitch and Lenovo Neptune liquid-to-air cooling in a 3U chassis on dual 3rd Gen Intel Xeon Scalable processors. Redundant low-pressure pumps and a closed-loop heat exchanger sustain SXM clocks in standard air-cooled racks.

Frequently Asked Questions
What does NVSwitch add over NVLink bridges?
The HGX baseboard's NVSwitch provides full all-to-all GPU connectivity rather than pairwise links, benefiting collective operations in training and HPC. We match the topology to your workload.
Does Neptune here require data-center water?
No. The liquid-to-air design rejects heat to air via a closed loop, installing in standard racks while delivering liquid-cooling density. We confirm airflow and rack fit.
Is this a fit alongside newer H-series nodes?
Yes, for extending an Ampere HGX footprint or HPC estates standardized on A100. We advise where Hopper would serve new workloads better.
