Can someone please help explain if it is possible (or advisable) to cable an MD1000 in Split mode, using both EMM's to connect to the same controller?

It seems there is conflicting information on the web about this and I'm a little confused whether I should be doing this for extra performance, or if it is not even supported.

Many thanks in advance:
