The NVMe interface standard doesn't make any assumptions about the underlying media of the device, so you can have Optane-backed NVMe just like you have NAND-backed SATA or NAND-backed SAS. For that matter, you don't need Kaby Lake to use Optane NVMe SSDs, for that same reason. Using Optane *DIMMs*, *does* require some hardware platform support, which may or may not be in Kaby Lake; I don't remember the details on that. -Ravi (rpokala@)
