QUESTION: Historically, we've Unix mirrored to multiple storage subsystems to provide continuous availability in the event of a storage subsystem failure. Is it reasonable to think this is not needed, on which platforms? In particular, what about Clariion?
ANSWER: There is not enough information here to comment properly but simple questions like what is your tolerance for downtime, how critical is your data and others of that vein come to mind. It is undoubtedly true that disk technology has matured significantly and MTBF is down from what it used to be. As to what that means to your specific business in terms of cost and risk, I can't advise on a strategy without more data.
