Can someone with knowledge put some light on how the newer EVA's is connected between controllers and disk shelfs? I know the EVA 5000 & 8000 had an switch option but if you don't get the switch option is all shelfs connected in a big loop? What about if you loose a whole shelf, wouldnt that bring the whole loop down and subsequently access to all shelfs?
Solved! Go to Solution.

Re: Question regarding EVA x400 and backplane FC loops
The cabling is made so that loop A goes from top shelf to bottom shelf, for example, and loop B goes in the opposite direction.
This way, even in the event of a entire disk shelf failing, the shelves above it can be accesed through one loop, and the ones below it through the other loop.
