Hi,
rados - Does not shard your object (as far as I know, there may be a striping API, although it may not do quite what you want)
cephfs - implemented on top of rados - does it's own object sharding (I'm fuzzy on the details)
rbd - implemented on top of rados - does shard into 2^order sized objects. (there's striping support in librbd as well).
radosgw - implemented on top of rados - I'd imagine this does shard into smaller objects as well
Cheers,
KJ

Here,I have a question. How to cut a large file into small objects?? it'done by the ceph itself or some other way ?
I try this command: rados put test-object xxx.iso --pool=data but the large file xxx.iso seem not be cut into small objects.
I feel confused. I wish some one can help me solve the question.
