We are living in the data age. There is a growing interest for large scale data-intensive applications such as social networks, enterprise applications, scientific applications and data mining. Those applications are mainly limited by the poor performance of existing storage technologies (e.g., disks and flash). Emerging fast non-volatile memory (NVM) technologies appear as a boon to those applications. However, the existing solid-state drive (SSD) architecture and software optimize for flash and are not adequate to exploit the full potential of fast NVMs. It instigates a revolutionary change...
