Forgive my ignorance, but I had no idea what single server durability was. So I had to look it up. I couldn't find any direct definitions, but from what I read it sounds like it does this: Single server durability is a disk buffered list of pending writes so if the server reboots while in operation it can just resume where it left off. In larger deployments this risk is handled by having multiple servers running concurrently. Does this sound right?
