I worked on Colossus at Google and Ceph is the closest thing out there. Gregory Farnum gave a great talk about it at the Open Source Summit 2017.
I heard from someone at a large company, though, that it's not getting a lot of love from Red Hat nowadays, even if you're a large paying customer. Now I'm curious.
Great to hear. I couldn't get more details from them, but it was something about both rebalancing and data recovery. They picked SwiftStack, which is at least in part open source. Maybe by now you have figured who that company is.
My team is still very interested in Ceph and Rook, for the record.
