Open Stack

Yan,

In my opinion, if you are going to spend all the time learning a new 
product -- i.e. nova network vs quantum.  And if you are only testing a 
concept, I would spend it upon Folsom and move from Essex and/or nova 
network and nova storage.  Quantum eases many of the issues Nova network 
has  or had, but quantum is the system for support and deployment going 
forward.... just my 2 cents...
