Crimson: Ceph for the Age of NVMe and Persistent Memory

Ceph is a mature open source software-defined storage solution that was created over a decade ago. During that time new faster storage technologies have emerged including NVMe and Persistent memory. The crimson project aim is to create a better Ceph OSD that is more well suited to those faster devices. The crimson OSD is built on the Seastar C++ framework and can leverage these devices by minimizing latency, cpu overhead, and cross-core communication. This talk discusses the project design, our current status, and our future plans.
