I completely agree with you ArrZarr
I've had countless discussions with Gartner on this one. We agree that the SSA and GPDA should merge. Let the Critical Capabilities Report sort out where individual arrays fit in various workloads.
Economics will resolve this soon, but hang on to your hat - there are other product segments Gartner reports on that I have to imagine will warrant their own MQ. Think Object Storage, Shared Memory Storage, the list goes on.
