Paper Title: Re-Architecting Cloud Storage with 3D XPoint and 3D NAND SSDs

Paper Abstract: As SSDs become more affordable, cloud providers want to use them to provide high performance, highly reliable services for their customers. 3DXPoint and 3D NAND TLC/QLC are the two latest non-volatile memory technologies to offer desirable features. 3D Xpoint fills the performance gap between DRAM and NAND-based SSDs while 3D NAND TLC reduces the cost gap between SSDs and hard drives. By re-architecting their storage with a combination of the two technologies, cloud service providers can offer higher performance and more reliable services with cost effective, high capacity/density storage. Example studies show results obtained with various combinations of currently available SSDs. A use case study shows the results for a Ceph cluster and a relational database service from a cloud provider. Further investigations will deal with shared storage consisting of 3D XPoint SSDs and ruler SSDs (in a new form factor).
