But now that we're off on this tangent... With a clustered netapp pair, what remains as a SPF? Do clustered shelves have any non-redundant components?
You could conceivably lose an entire shelf. I can't say for sure what might happen, not knowing the hardware internals of an FC-[78] disk shelf, but something between the FC-AL loops and the drives themselves (the backplane, perhaps?) could go wonky. Power, cooling and drives would all still be operational, but the drives would not be visible to either the A or B loops in a cluster. Another variation on the double/multi-drive failure. ;-)
