Hi@MD,
To use Ceph, follow the below given steps.
- 
Install the RADOS object server:
 sudo python setup.py install
 
- 
Modify your object-server.conf to use the new object server:
 [app:object-server]
 use = egg:swift_ceph_backend#rados_object
 
- 
Set the user and pool for Ceph in the [DEFAULT] section in the same file:
 [DEFAULT]
 rados_user = swift
 rados_pool = swift
 
Hope this will work.
Thank You
