Inquiry about PCIe Architecture and P2P DMA Support on Dell PowerEdge T560

Dear Dell Support,

I am considering using the Dell PowerEdge T560 for GPU-DPU communication and would like to clarify its PCIe architecture. Specifically, I have the following questions:

1. What is the PCIe topology of the PowerEdge T560 motherboard?
2. Does it support PCIe Peer-to-Peer (P2P) Direct Memory Access (DMA) between devices such as GPUs and DPUs?
3. Are there at least two PCIe slots connected to the same root complex?
4. Can the PowerEdge T560 support GPUNetIO for direct GPU-DPU communication over PCIe? If so, are there any specific BIOS settings or hardware configurations required?

Your insights would be greatly appreciated.

Best regards,
Hsinli
