[SPDK] Re: a distributed storage system base on SPDK

If you’re an SDC attendee you should be able to see the presentation video and slides, which provide an introduction. If not, I can send you a copy. 

This should all be in the README, but I pushed the patch without that finished so the code would be visible before SDC. I’ll update the patch when that’s finished.
