Not a lot of people are publicly discussing their sizes on things like
that, unfortunately. I believe DreamHost is still the most open. They
have an (RGW-based) object storage service which is backed by ~800
OSDs and are currently beta-testing a compute service using RBD, which
you can see

Nothing prevents me to offer a service directly based on RADOS API, if
S3 compatibility is not needed, right ?
Correct, That is librados.
What I don't understand is how can I access a single file from RGW. If
LibRBD and RGW are 'gateway' to a RADOS store, i'll have access to a
block
In this case, can a single block device (for example a huge virtual
machine image) be striped across many OSDs to archieve better
performance in reading?
an image striped across 3 disks, should get 3*IOPS when reading
Yes, but network (and many other isssues) must be considered.

It's not magic — I haven't done extensive testing but I believe people

Any contraindication running mon in the same OSD server?
Generally that's considered OK. ceph-mon

In this case, should I reserve some space to ceph-mon (a partition or
a dedicated disk) or ceph-mon

Hi all,i'm new to ceph.
Are RBD and REST API production ready?
There are sites using them in production now.
Do you have any use case to share? we are looking for a distributed
block storage for an HP C7000 blade with 16 dual processor
That's great but if you go the way of having for example 8x OSDs per
server with 8 single Disks - how can i archieve that ceph is splitting
my files to the correct servers for redundancy?
I believe this is handled by CRUSH:

Hi,
I'm going to build a rados block cluster for my kvm hypervisors.
Is it already production ready ? (stable,no crash)
I have read some btrfs bugs on this mailing list, so I'm a bit scary...
Also, what performance could I expect ?
I try to build a fast cluster, with fast ssd disk.

Hi Christian,
thanks for your response.

partition lately which caused our cluster to halt).

Thanks Christian for doing an awesome job, you answered some of the
questions better than I personally could have ;)
