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.

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