I'm planning to add a X2072A card to my FAS8300.
I have 2 stacks today, using port 0a/0d to one stack and 0b/0c to another stack.
PCIE slot 1 and 2 is taken so I'm planning setting it to slot 3 since its the first slot thats available on HWU priority chart.
Which ports should I move? and to what port? 0d -> 3d and 0c -> 3c?
Is there somewhere you can see what ports should be used?

End up with 0a/3d (stack 1) and 3a/0d for stack 2
ANything really works. The X2072 has a single ASIC. The old cards used to have two asics so it was more important to split IOMA/IOMB on different ASICs.
Today, I still cable
0a / 1d
1a / 2d
2a / 0d
1c / 2b
2c / 3b
3c / 1b
For historical puposes and to prove my brain hasnt given out. I did a frankencluster with 10 stacks. I followed that logic and it was easy/trivial to no make a mistake.
In your case
keep 0a at 0a
move 0d -> 3d
You could keep 0c
move 0b -> 3b
Or (to move as above while the node is down)
keep 0a at 0a
move 0d -> 3d
move 0c -> 3a
move 0b -> 0d

Alright, I see.
Is that a general thing that newer cards run a single ASIC? is it displayed on HWU?
Just so I don't have to ask next time...
But I really appreciate the answer! 🙂

Knowledge I’ve picked up from smart people in NetApp engineering
There is a sas cabling guide in the documentation area but it goes through a complicated procedure on a spreadsheet.
The pathing I indicate above dues the same thing with less shifting and complications.

...or just removing the heatsink and taking a look 🙂
