Object storage file system

HI

in CL110, Chapter 8, MANAGING OBJECT STORAGE

- The Object Storage Service uses virtual object containers to allow users to store and retrieve
files and other data objects without a file system interface

However, in another part of the same chapter, it says

- The object service stores objects on file systems. XFS is the recommended file system

can anyone explain the difference

Probably it means that the underlying object store based on Ceph, is using XFS below Ceph

There is a new option in Ceph, called Blustore, that get rids of the intermediate XFS filesystem layer

Indeed, as @Rodolfo states, one sentence refers to the external interface that the object storage clients use (which "allow[s] users to store and retrieve files and other data objects without a file system interface"), and the other sentence is about the internal implementation of object storage service, which is indeed pluggable and can in CEPH currently be a choice between XFS- and Bluestore-based storage (and clients never see or hear about that, and the choice and tuning of these settings never affect the fundamental way the clients interact with the object storage service).

Cheers,
