Hi Michael,

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!

Thanks,
Ben

hi everyone,

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.

regards,
michael
