Referencing DMA engine, do you mean Vanderpool ? It is http://download.intel.com/technology/computing/vptech/Intel(r)_VT_for_Direct_IO.pdf According to Intel marketing-talk, I/OAT is a couple of things, including MSI-X, VT-d (i.e. IOMMU/Vanderpool), something called Intel(R) QuickData Technology (might be, you mean this one ?) and DCA.
