This is a pretty comprehensive paper on RAMCloud, including details on its data model, log structured storage and cleaning, fast crash recovery, and networking with performance breakdowns. It doesn't include secondary indexes, transactions, or any other features developed after its publication date.

This is my Ph.D. dissertation on the Raft consensus algorithm. It's a much extended version of In Search of an Understandable Consensus Algorithm (see below). It also describes a simpler form of cluster membership changes, which we weren't aware of at the time the conference paper was published.

This paper describes the Raft consensus algorithm. The conference version was limited in space, and the extended version adds a couple of pages to discuss log compaction, client interaction, and a couple of other minor topics. My Ph.D. dissertation (see above) expands on the same ideas.

Rumble, Eric Stratmann, and Ryan Stutsman. The Case for RAMCloud. Communications of the ACM (CACM). July 2011.
This is a slightly revised and shorter version of The Case for RAMClouds, which appeared in Operating Systems Review in 2009. The students on the project didn't like having "RAMClouds" in the title, which some people had assumed was the project's name, so the "s" was dropped in the newer revision. I joined the RAMCloud team shortly after the OSR paper was written.
