Do you mean in GNR compared to using (san/IB) based hardware RAIDs? If so, then GNR isn’t a scale-out solution - you buy a “unit” and can add another “unit” to the namespace, but I can’t add another 30TB of storage (say a researcher with a grant), where as with SAN based RAID controllers, I can go off and buy another storage shelf.
