The Dell PowerEdge 2x8 Butterfly Riser Card (9PD6H) features two PCIe Gen 3 x8 slots positioned on opposing sides of the riser, enabling balanced and efficient expansion in supported PowerEdge systems. This layout is often used in compact servers like the R450.
Engineered for low-profile, half-length cards, this riser maximizes PCIe availability without increasing the chassis footprint. It’s ideal for enhancing I/O capabilities with dual-slot support in constrained server environments.
