Gazzoni,
you mix things up here. The SAN example i brought up here has been for SCC - the same thing you are doing now. For CCR you can use DAS (Direct attached storage). The configuration does not even have to be on the certified cluster hardware list in this case.
Large Custumers might tend to stay on a SAN configuration even in with CCR. The reason herefor is that from a TCO point of view it does not make sense to move to DAS when you already have everything running everything else on SAN. (think about 40-200 servers here).
In CCR which uses MSN (majority node set) you also should be able to restore the cluster config quite easy. You only need to take care of the withness share and one node - thats it.
