About the Cinder iSCSI traffic

Hey guys,

There is this little thing that I'm wondering about regarding the use of Cinder. The situation is: I have Cinder installed on my Controller Node and it assigns some memory for one of the VM's, and the Controller Node is connected to a SAN using an iSCSI connection. I would have set up a Storage Network in between the Controller and Compute Node. Now Cinder will take care of creating an iSCSI connection between the Compute Node and the SAN right?

Will all this iSCSI traffic go from the Compute Node straight to the SAN? Or will all the iSCSI traffic go from the Compute Node, throught the Controller (Storage) Node, to the SAN?
