How many active paths per a LUN on using active/active array controller.

Hello everyone,

I have a symmetric active/active array controller and two HBAs on the ESXi host(also two SAN switch).

In that case, I have 4 paths per a LUN, right!

I wonder how many active paths per a LUN exist at the same time when I set the round robin PSP.

and also how many marketshares of active/active array controller against active/passive array controller in the production roughly.

Thanks All.
