PCIe/104 and PCI/104-Express Specification Revision 3.0 February 17, 2015 Page 39
Figure 4-6 illustrates a Host with a PCIe/104 Type 2 connector going down and a PCIe/104 Type 2 connector going up.
The Host does not have the top and bottom busses connected so, as in this example, it can support up to 4 SATA Devices.
In this example Type 2 and Universal Devices are stacked either above or below the Host or both at the same time.
