Paper Title: Building High Performance, Cost-Effective Ceph All-Flash Arrays

Paper Abstract: As SSDs become more affordable, many cloud providers are providing high performance, highly reliable storage for their customers based on all flash arrays. Ceph is a popular scale-out storage solution for such requirements as it offers block, object, and filesystem storage in one platform. However, it requires lots of optimization and tuning to achieve high performance. A proposed reference architecture offers high performance and optimal configurations for Ceph bluestore using RDMA technologies. The architecture shows that Ceph is capable of fully utilizing SSD capabilities with the right optimizations. A TCO model and IOPS/TB and IOPS/$ measurements based on the reference architecture show that the Ceph high density solutions are economically sound. Even better solutions can be implemented using the Ceph all-flash arrays with NVMe-oF technology.
