The First Principle of Big Memory Systems

Persistence is the first principle of big memory systems. We comprehensively analyze the vertical and horizontal extensions of existing memory hierarchy. Networks are flattening traditional storage hierarchies. We present the state-of-the-art studies upon the big memory systems, together with design methodology and implementations. We discuss the full-stack and moving persistence. In order to achieve cost efficiency and deliver high performance, we present the speculative and deterministic persistence.
