Can the NVM Express (NVMe) driver
driver-storage-nvme for Illumos be considered usable? It would be nice to use e.g. an Intel DC P3700 PCIe drive for L2ARC as the SAS2 and 3 SSD drives are awfully scarce/expensive at the end of the Channel available to me.
The only reference to an nvme driver for Illumos I could find is https://www.illumos.org/issues/4053
There are a few not too encouraging messages in forums on the topic, for example: http://comments.gmane.org/gmane.os.illumos.devel/14870 and http://comments.gmane.org/gmane.os.illumos.devel/14904
But those are from almost a year ago. Any further details on the state of the driver and an estimate whether it would be sane to consider to actually use it for a production system which is not life critical would be most welcome.
