There isn't a SCSI interface on the planet where a SCSI disk instructs the SCSI host adapter which host memory address to write to. Nor an IDE/ATA/SATA one for that matter. That would be insane.

But a hacked SCSI adapter can ignore the address of the transfer given by Linux and instead do a DMA anywhere.
Same for a hacked IDE adapter, and mostly for PCMCIA/CardBus card accessible on a lot of PC without opening the box.

Yes, if you take over some device directly attached to the memory or PCI bus of a machine you can access anywhere in RAM
with firewire this doesn't take hacking the card, it's a normal mode of operation.

The three transport protocols where SCSI can use some form of remote DMA are FireWire, InfiniBand, and iWARP.
