Any help would be greatly appreciated. Thanks in advance
It tells how ratio between device ports and isl port for the fabric.
So for each 1 ISL port you have 34 device ports in your fabric.
Thanks for your help Dion.
's post is correct, so please, mark the answer as correct so that your post can resolve other people's doubt.
On the other hand, the Fan out ratio comes from the following formula:
/ ISL number
In your case:
Fabric B: / 4 = 34
Fabric A: / 8 = 16.5
