Nice marketing, but ..
Today its hard to tell with all the Marketing spins
but AFAIK Hedvig is not a scale-out NAS or object solution rather a scale-out Block storage, no different than EMC ScaleIO with standard Linux FS installed on that LUN
Correct me if i'm wrong, what they do is implement (a single) NAS or Object protocol head over a distributed virtual block device (LUN), this means the FS or Object layer doesn't scale, and there is no (distributed) Metadata awareness, or built-in metadata search capabilities, which are very fundamental for modern object or scale-out NAS solutions
