Product Description
The G5 2U X8X8 Riser Card (Slot 3) is an expansion component for G5 series servers, specifically designed to support the installation of two Full-Height Full-Length (FHFL) GPUs. Here's a detailed breakdown of its key specifications and features:
1. Product Positioning & Compatibility
- Server Models: Primarily used in 2U dual-socket rack servers like the UniServer R4900 G5.
- Slot Installation: Installed in Slot 3 of the server.
- GPU Support: Accommodates two FHFL-form factor GPUs, each with a maximum power consumption of 150W (total 300W).
2. Technical Specifications
- PCIe Channel Configuration: The "X8X8" designation indicates each GPU is allocated x8 PCIe lanes, totaling x16 lanes (x8 + x8) for dual-GPU operation. This is compatible with PCIe 4.0 or higher server platforms.
- GPU Compatibility: Supports mainstream GPU models (e.g., NVIDIA T4, A10), but specific compatibility must be verified through H3C's official compatibility list or documentation.
3. Power & Cooling Requirements
- Power Supply: The combined 300W power draw for two 150W GPUs requires a server power supply unit (PSU) that meets the total system power requirements (additional PSU specifications should be confirmed via the server's official documentation).
- Cooling Considerations: The server's cooling system (e.g., fans, airflow design) must be capable of managing the heat generated by dual high-power GPUs to ensure stable operation.
4. Deployment Models (CTO & BTO)
- CTO (Configure to Order): Allows customers to customize the server configuration by adding this riser card and GPUs based on specific needs.
- BTO (Build to Order): Enables pre-integration of the riser card and GPUs during server manufacturing, ensuring seamless compatibility and reduced deployment time.
5. Key Use Cases
- Ideal for applications requiring high-performance computing (HPC), artificial intelligence (AI) training/inference, data visualization, or virtualization workloads that benefit from dual-GPU acceleration.
