SYS-422GS-NB3RT-ALC
High-Density 4U Liquid-Cooled HGX AI GPU Server featuring NVIDIA HGX B300 with the SYS-422GS-NB3RT-ALC
The SYS-422GS-NB3RT-ALC is a 4U rack-scale liquid-cooled Supermicro HGX platform designed for sustained AI training and HPC acceleration, pairing an NVIDIA HGX B300 8-GPU SXM baseboard with dual Intel Xeon 6 processors (Granite Rapids, Xeon 6700 with P-cores). This architecture targets maximum GPU residency and deterministic performance under long-duration LLM pre-training and fine-tuning cycles.
To keep the GPUs fed, the SYS-422GS-NB3RT-ALC combines 32x DDR5 ECC RDIMM channels for up to 8TB system memory with a PCIe 5.0 expansion design for high-throughput fabrics and I/O. The HGX B300 subsystem delivers 288GB total HBM with NVLink and NVSwitch for low-latency, high-bandwidth GPU-to-GPU communication, while storage is optimized for fast dataset staging via 8x E1.S NVMe hot-swap bays plus dual M.2 NVMe boot devices. Integrated 8x OSFP 800GbE (ConnectX-8 SuperNIC) enables dense multi-node cluster fabrics without sacrificing front-to-back serviceability.
Why Choose the SYS-422GS-NB3RT-ALC?
The SYS-422GS-NB3RT-ALC provides a balanced density-to-performance profile by concentrating 8 SXM GPUs in a liquid-cooled 4U envelope with enterprise power redundancy and serviceable NVMe. This makes it suitable for scaling out GPU clusters where network bandwidth, thermal stability, and predictable scheduling matter as much as raw accelerator throughput.
Supermicro engineering emphasizes data centre-aligned modularity, validated platform integration, and lifecycle reliability. With secure boot, signed firmware, Silicon Root of Trust, and a TPM 2.0 header, the SYS-422GS-NB3RT-ALC supports controlled deployment in regulated enterprise environments while leveraging Supermicro management tooling for fleet visibility.
Key Applications:
- LLM pre-training and fine-tuning
- GPU-accelerated HPC simulation
- Multi-node NVLink/NVSwitch GPU compute
- High-bandwidth 800GbE AI cluster fabrics
At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your SYS-422GS-NB3RT-ALC deployment plan and the option to extend the warranty up to 6 years to protect long-term GPU cluster investments.
