With EQL suggesting to have all ports on the Storage NIC in one LAG, that LAG needs to go to one physical unit/stack. And should not be split up across multiple seperate switches. With that in mind, plus trying to keep with idea of redundancy, I would suggest a combination of the two.  [IMAGE]   With the above you end up with some redundancy from storage unit to the stack, plus some redundancy from stack to stack.
Hi I'm about to deploy an iscsi network for SAN (eql). I'm going for this design. I'm using two PC5548 though [IMAGE] My question is what are the benefits of stacking the two switches? If I just cross/split connect them shouldn't they be redundant?
