P2P over PCI/PCI-X is quite common in devices like raid controllers.

Hi Dan

Do you mean between PCIe devices below the RAID controller? Isn't it pretty novel to be able to support PCIe EPs below a RAID controller (as opposed to SCSI based devices)?

I'm thinking of the classic I/O offload card where there's an NTB to
an internal PCI bus that has a storage controller and raid offload
engines.
