We are in the process of preparing to upgrade our FAS270 with 2 shelves to a FAS2050. The FAS2050 will use internal drives, and we will make use of the existing two shelves from the FAS270 as well. The configuration was, and will still be, active/active.
The parts came in and we have two ESH4 modules, presumably to replace in the exisitng two heads in the FAS270.
So the question is how are the fiber connections made from the heads, to shelf 1 to shelf2? Do these cascade (using the up, down ports) or does each connection have to go back to the filer head itself?
Thanks in advance, and points will be awarded!
