High-Density 5U Deskside GPU Server featuring NVIDIA Grace Blackwell Ultra Superchip with the ARS-511GD-NB-LCC
The ARS-511GD-NB-LCC is a 5U rack/tower-convertible AI workstation and GPU server built around the NVIDIA Grace Blackwell Ultra Superchip, coupling an Arm-based Grace CPU with an onboard Blackwell B300 GPU through NVLink-C2C for coherent, high-bandwidth CPU-GPU operation. This architecture targets engineers who need deterministic latency for on-prem inference and fast iteration loops for local model prototyping and fine-tuning.
Memory is delivered via LPDDR5X ECC SOCAMM across 4 slots, with 496GB configured and scalability up to 775GB of coherent CPU+GPU memory, reducing data movement overhead for data-intensive HPC and research pipelines. PCIe 5.0 expansion provides 1x x16 and 2x x8 (x16 mechanical) FHHL slots for accelerator, DPU, or high-speed I/O integration, while the onboard B300 is not constrained by a PCIe slot topology. Storage is optimized for low-latency NVMe with 4x M.2 2280 sockets for primary drives, complemented by an M.2 2230 PCIe 5.0 x4 E-Key socket for optional non-storage expansion modules.
Why Choose the ARS-511GD-NB-LCC?
The ARS-511GD-NB-LCC consolidates Grace CPU throughput, Blackwell GPU compute, and coherent memory semantics into a compact 5U footprint, delivering a strong density-to-performance ratio for edge-to-core deployment. The ARS-511GD-NB-LCC supports scalable networking with dual 400GbE QSFP28 ports via an NVIDIA ConnectX-8 SuperNIC plus 10GbE and dedicated BMC management, enabling rapid integration into modern fabric designs with consistent operational control.
Supermicro engineering emphasizes serviceability, platform validation, and data-centre-aligned management, combining integrated BMC/IPMI, AMI UEFI BIOS, and a Silicon Root of Trust (NIST 800-193) to protect firmware integrity. The closed-loop liquid cooling design with direct-to-chip cold plates supports sustained performance under continuous AI and HPC duty cycles.
Key Applications:
- Local LLM fine-tuning and prototyping
- Low-latency on-prem AI inference
- Data-intensive HPC and research computing
- High-bandwidth 400GbE model serving
At Happyware - Server Hardware you benefit from non-binding offers tailored to your ARS-511GD-NB-LCC deployment goals and an extended warranty of up to 6 years to secure long-term operation of this liquid-cooled Grace Blackwell platform.
