Thank you for your inquiry. While it is possible for the OCulink connections to accept SAS/SATA connections, there are two factors in terms of usage with our products. One factor, especially for our current PCIe products and this concept product, is that these specific drive cages are designed with use of PCIe NVMe drives, not SAS/SATA. The other major factor is the setting on the controller that has the OCulink connection. Some controllers have settings that either choose between SAS/SATA or PCIe NVMe drive connections. The cabling can allow both types of drive connections to go through but the host and the drive would determine the connection type the OCulink would be.
If you have additional thoughts or comments on our concept products, please let us know.
