Product Description
The "G5 2U 3X16 Riser (slot 1/2) (supports 2 FHFLs and 1 FHHL, supports 2 150W GPUs)" is a high-performance riser card designed for 2U rack servers, enabling flexible expansion of PCIe devices with dual GPU support. Below is a detailed breakdown of its specifications, features, and applications:
Core Specifications
- Form Factor: 2U rack server compatibility, optimized for space-constrained data center environments.
- Riser Configuration: 3x PCIe slots with X16X16X16 bandwidth allocation (PCIe 4.0/3.0):
- 2 x PCIe 4.0 x16 slots (for high-bandwidth GPUs/NICs)
- 1 x PCIe 4.0 x16 slot FHHL )
- Slot Positions: Designed for server's slot 1 and slot 2 (motherboard-specific mounting points).
- CTO & BTO Support: Customizable via Configure-to-Order (CTO) or Build-to-Order (BTO) for power, thermal, or OEM branding.
Device Support Capabilities
- Expansion Card Types:
- 2 x FHFL (Full Height Full Length) cards: e.g., full-size GPUs (NVIDIA A10, AMD MI25), high-end network adapters (100G NICs).
- 1 x FHHL (Full Height Half Length) card: e.g., low-profile SSD controllers, half-length NICs.
- GPU Support:
- Specifically supports 2 x 150W GPUs (total 300W power budget), ideal for mid-range AI inference, virtualization, or graphics workloads.
- Requires dual 8-pin PCIe power connectors (or server-integrated power delivery) for GPU power.
