Paper Title: An All-NVMe Performance Deep Dive into Ceph

Paper Abstract: Recent significant Ceph improvements, coupled with NVMe technology, will broaden the classes of workloads that Ceph can handle. The compelling speed and low latency of NVMe SSDs are obvious, but optimally harnessing them for I/O-intensive applications in shared VM storage environments is often non-trivial. An example describes the work involved in designing, deploying, tuning, and testing the latest all-flash accelerated Ceph reference platform leveraging NVMe SSDs. A new tuning and performance testing methodology had to be developed. Performance results cover FileStore vs. BlueStore optimizations with all-NVMe clusters for the latest Ceph version (called Luminous).
