Supposedly the 760 can have up to 24 fcal shelves. Now, that is a whole lot of disk shelves (3 racks worth, give or take). How far can the fcal cable be and what sort of performace hit do you take on that 3rd loop (since each loop can only consist of 8 shelves)?
You figure, the last shelf in the 3rd loop is going to be more than a few meters away from the filer...
Does that make sense?
