Every once in a while, a discussion on one of the storage blogs turns to MPFS/HighRoad, how it relates to what is now known as pNFS, what differentiates it from alternatives such as GFS, Lustre, etc. Most recently, the comments in a post on Chuck Hollis’s blog demonstrated some confusion or misunderstanding about the project’s various names. I tried to clear up that one issue there, but it occurred to me that even though I spent more time on MPFS than on any other project in my career except for the one at Revivio, I’ve written less about it than about what came immediately before or after. To correct that, I wrote a History of MPFS page. If you’re interested in what someone who was actually there at the beginning might have to say about some of the mythology and misinformation surrounding the project, you might want to give it a read.
