Hi, For later reference. Who knows ... ;) http://paulormg.files.wordpress.com/2012/08/thesis-paulo.pdf
that is very interesting! That was exactly what we were talking about during the Ceph meeting @ FOSDEM'13. We have been running a similar design in production for over 1.5 year now, with Synnefo [1], first over NFS and now over RADOS. Specifically, the Storage Service of Synnefo, called Pithos, stores content-addressable objects on the underlying storage, allowing us to do file syncing with native clients, not only for files but for VM Images, too. We even have an extension for the OpenStack Object Storage API (which is what we expose to the users), to allow us for these advanced operations, the same way Paulo proposes. If anyone is interested towards that direction, which we believe allows for very interesting things to be done, please take a look at the Pithos design and the corresponding OpenStack API: http://www.synnefo.org/docs/synnefo/latest/pithos.html#pithos-design http://www.synnefo.org/docs/synnefo/latest/pithos-api-guide.html#the-pithos-api The first document is somewhat outdated (sorry for that :)), but the concepts are there and have been tested in production. Again, we are very happy to see other people exploring those paths in the cloud context too.
