- Four USB ports for versatile peripheral connections.
- A VGA port for display purposes.
- Power button and status LEDs for operational visibility.
This server also incorporates dual 1GbE and management ports located at the front, allowing for easy access to network management tools. The innovative design enables users to reroute Ethernet cables for rear I/O access if necessary, providing flexibility in deployment scenarios.
GPU and PCIe Switch Configuration
At the core of the ASRock Rack 8U8X-GNR2 is the NVIDIA HGX B200 8-GPU tray, which is a highlight of this server. This assembly significantly boosts the server's computational capabilities, making it especially suitable for machine learning and deep learning applications.
The integration of a PCIe switch board at the rear bottom of the system enhances data flow between the GPUs and the motherboard, while the blind mate power connectors ensure reliable power delivery to the GPUs. The intricate cabling design, while extensive, is organized to avoid interference with component access and maintenance.
Processor and Memory Configuration
Equipped with two Intel Xeon 6 CPUs, specifically from the Xeon 6700P, 6500P, and 6700E series, the server excels in processing power. This architecture supports:
- Eight channel 2DPC memory configurations, allowing for a maximum of 32 DDR5 DIMMs.
- Support for over 1.4TB of GPU memory, ensuring that the system can handle even the most demanding workloads without memory bottlenecks.
- The advantage of additional DIMM slots, allowing for greater capacity without the need for higher-cost DIMMs.
Despite the complexity of the internal configuration, ASRock has designed the server for ease of servicing. The layout allows for relatively straightforward access to DIMMs, making upgrades and maintenance manageable even in high-density deployments.
Advanced Cooling Solutions
Cooling is paramount in a high-performance server, especially one designed for AI applications that generate significant heat. The ASRock Rack 8U8X-GNR2 features:
- Large dual fan modules that facilitate optimal airflow across critical components.
- A strategic layout that ensures efficient heat dissipation from both the CPUs and GPUs.
- Integrated sensors that monitor temperature, allowing for dynamic adjustments to airflow as needed.
This approach not only enhances performance but also extends the longevity of the server by preventing overheating during intensive tasks.
