openstack ceph concept
HI Openstack ceph experts, For those of you who knows openstack ceph - can you please clarify the following for me: - Ceph is known as the unified storage solution (i.e. file, block and object storage) - what does that really mean? Does that mean you can create files (file storage), volumes (block storage like cinder) or objects (object storage like swift) in ceph? If you are only using ceph as file storage, are the files still stored as objects inside RADOS? Likewise if you use it as block storage, does that mean the volumes are stored as block in RADOS but appear to the application as volumes (blocks)? I haven't actually installed ceph yet but do you actually get an option on whether you want create file system or volumes or objects under the ceph menu? I am doing some research on the internet but if somebody can explain this to me, that would be great. thanks in advance!
