Here is my latest proposal(https://cwiki.apache.org/confluence/display/= CLOUDSTACK/Storage+subsystem+2.0), and sample code is at engine/storage/src= /org/apache/cloudstack/storage/volume/, engine/storage/src/org/apache/clou= dstack/storage/datastore/ and engine/storage/src/org/apache/cloudstack/stor= age/image/ on javelin branch. The ideal is very simple, delegate the logic into different components, = into different identities. I'll try my best to get rid of the monolithic ma= nagers, which are hard to extend. Feedback and comments are welcome. --_000_C66C814C1ABFA8449FF65CB44953A8B4012CBD6F7E2FSJCPMAILBOX_--
