Re: what is difference between A/A and A/A/A

I would say that asymmetric active-active is just typical scenario - both paths / controllers are active, but in fact only one controller 'owns' certain LUN (so called preferred path).

So saying 'active-active' you would really mean 'asymmetric a/a'.

More knowledgeable colleagues - correct me if I am wrong.

Yep, I agree, although I won't claim I am more knowledgeable ;-)

VA and EVA belong to the AAA group of arrays.
