of a storage subsystem failure. Is it reasonable to think this is not needed, on which platforms? In particular, what about Clariion?
You are doing the right thing. All storage subsystems have single points of failure, including Clariion boxes. Consider the power source, the cache boards, internal controllers. Also consider the box itself. If a large cup of a sticky-sweet beverage were to be poured into a Clariion, it would almost certainly fail. I have never seen any single-box solution that did not have single points of failure. By mirroring to another subsystem, you are protecting yourself against the failure of a single subsystem.
