Why is split responsibility appealing? In almost any complex system whether it be government or computing, split responsibility results in indecision and confusion. Heirarchical decision making based on common rules is another matter entirely. Unfortunately SAN equipment is still based on technology developed in the early '80s and simply tries to behave like a more reliable disk drive rather than a participating intelligent component in a system which may detect, tolerate, and spontaneously correct any faults.
