If a 3D XPoint based NVMe drive was released, using SPDK's NVMe driver would be an
excellent choice for getting the best possible performance inside of a dedicated storage
application. The SPDK NVMe driver should work with any device that is compliant with the
NVMe specification. This includes any potential upcoming 3D XPoint based devices, but also
current NAND-based devices and possibly even the emulated NVMe device available through
QEMU. We currently test the SPDK NVMe driver against Intel P3700 series SSDs, so I cannot
make any guarantees that the driver works in other environments. If you try and find any
problems, please do send us patches!

i am curious as to whether spdk would be the right library to be using to access 3dxpoint,
once 3d xpoint comes out and becomes publicly available... given both spdk and 3dxpoint
come from intel, and spdk is all about getting as much performance as possible from nvme
storage devices. should i be looking at using the nvme specific driver?
also, is there any ability to fake the presence of devices? I frequently run in
virtualized environments, and it would be great to be able to interact and use the API
without requiring a physical NVME device connected.
