on symmetric access by all clients to shared block devices, Ceph
separates data and metadata management into independent server
clusters, similar to Lustre. Unlike Lustre, however, metadata and
storage nodes run entirely as user space daemons. Storage nodes
utilize btrfs to store data objects, leveraging its advanced features
(checksumming, metadata replication, etc.). File data is striped
