Grace Blackwell Ultra in a 5U Chassis
The Supermicro Gold Series ARS-511GD-NB-LCC-01-G2 is a 5U rackmount AI system built around the NVIDIA GB300 Grace Blackwell Ultra Desktop Superchip. Its black chassis includes detachable feet, allowing conversion to a full-tower configuration for installations where a traditional rackmount setup is not required.
NVIDIA Grace CPU and Blackwell Ultra GPU
The system combines a 72-core NVIDIA Grace CPU based on Arm Neoverse V2 architecture with an NVIDIA Blackwell Ultra B300 GPU featuring 252GB of ECC HBM3e memory. This tightly coupled CPU-GPU architecture provides a platform for demanding AI development, inference and accelerated computing workloads.
748GB of Coherent LPDDR5X Memory
The configuration features 748GB of coherent LPDDR5X memory, bringing substantial system memory capacity to the Grace Blackwell Ultra platform. The coherent memory architecture supports data sharing between the CPU and GPU, helping applications work with large datasets across the combined computing architecture.
Four M.2 NVMe SSDs
Storage comprises 2x 960GB M.2 NVMe SSDs and 2x 1.92TB M.2 NVMe SSDs, providing 5.76TB of combined raw SSD capacity. The motherboard also supports a pair of PCIe Gen6 M.2 drives.
ConnectX-8 High-Speed Networking
An NVIDIA ConnectX-8 SuperNIC provides high-bandwidth networking through 2x QSFP 400GbE ports. This connectivity supports demanding data-transfer requirements and high-speed communication with compatible network infrastructure, making it well suited to AI environments where rapid movement of data is essential.
Dedicated Management and 10GbE Connectivity
Alongside the dual 400GbE interfaces, the system includes 1x RJ45 10GbE LAN port for network connectivity and 1x dedicated 1GbE BMC LAN port for remote management. Redfish API and IPMI 2.0 with KVM support provide additional options for remote administration and system control.
Direct-to-Chip Liquid Cooling
Thermal management combines direct-to-chip (D2C) cold-plate liquid cooling with a dedicated fan arrangement comprising 2x 140mm fans, 2x 80mm fans and 1x 60mm fan. This cooling configuration addresses the thermal demands of the Grace Blackwell Ultra hardware while maintaining airflow through the chassis.
1600W Titanium Power Supply
A 1600W Titanium-level power supply provides system power delivery, with a rated efficiency of 94%. This single-PSU configuration supplies the power infrastructure for the integrated CPU-GPU platform, memory, storage and networking hardware.
Flexible I/O for Workstation Deployment
Front connectivity includes 2x USB 3.0 Type-A ports, while the rear provides 4x USB 3.0 Gen2 Type-A ports, a mini-DisplayPort output and rear audio connectivity. This selection supports peripheral connections and local access in both rackmount and tower installations.
Hardware Monitoring and System Security
Built-in monitoring covers CPU cores, chipset voltages, memory, fan speeds and CPU and chassis temperatures. Chassis intrusion detection adds a further layer of physical security monitoring, while tachometer-equipped fans and thermal controls support ongoing system health oversight.
Supermicro Management and Firmware
The system uses a Super GPU-NVGB300-WSHPM proprietary motherboard with an AMI 64MB SPI Flash EEPROM BIOS. Redfish API and IPMI 2.0 with KVM support provide management and remote-access capabilities for administration in professional computing environments.
