Please accept my apologies for the long delay in responding. This turned out to be a much larger explanation than I originally thought. Rather than send a wall of text in email, I moved it into file and uploaded it to the server; interested parties can view it here: https://people.freebsd.org/~rpokala/2017-03-24.nvdimm.txt I'll do my best to answer questions and/or make the proper introductions with the people inside Panasas who can. Thanks for your interest, Ravi (rpokala@)
