The two DataCore SPC-1 results as submitted do not have any HA. They are akin to a single controller storage device. It is much easier to obtain higher performance if there is no controller resiliency. Also, the single controller configuration reduces cost dramatically. I don't know any customers running application workloads on single controllers!
DataCore is a software defined storage solution, and suits very different workloads to the shared external arrays with HA and controller resiliency. So I think it is reasonable to not make direct comparisons between the two DataCore results and external shared array results.
