It's not necessarily *better*, but it's no longer a difference. One of the big whines we hear constantly is that "having a mainframe makes us have to buy special-purpose stuff that's so different from our other systems that we have to get special training for our staff". Being able to use the SAME stuff is a positive thing. As Ann said, it's sometimes slower than the ECKD support, but if it saves having the "another weird mainframe device cost" argument, that may be enough to make it worth while.
