Ceph OSD Performance: Backends and Filesystems

Ceph OSD performance on various filesystems and backends including btrfs, for the Atlanta ceph meetup.
Ceph OSD performance characteristics are one of the most important considerations when deploying a RADOS (Replicated Asynchronous Distributed Object Storage) cluster. Ceph is an open source project for scale out storage based on the CRUSH algorithm. An OSD is an “Object Storage Daemon”, which represents a journaling partition and a data storage partition in the Filestore backend implementation. An OSD is, in a broader sense where Ceph stores objects which hash to a specific placement group (PG).
