FAS and V-Series Storage Systems Discussions
Does the cabling below look correct? This is a FAS2240-2 with a DS4243 Shelf.
Left Controller Square > Top Shelf Module Square
Right Controller Square > Bottom Shelf Module Square
Left Controller Circle > Bottom Shelf Module Circle (flipped)
Right Controller Circle > Top Shelf Module Circle (flipped)
You flipped the end of the stack perfectly, but the way you cabled it would mess you up when you need to hot add a shelf.
ACP looks perfect.
Are you sure? According to the documentation, circles are connected to squares and squares are connected to circles.
Correct the Circle <-> Square relationship needs to be maintained.
Did this ever get answered?
I have inherited the same setup but I'm pretty sure it is cabled incorrectly.
Run the config advisor or wire gauge to find the health of your HA pair. That will give complete answer.
You will not be able to download the config-advisor or wire gauge, please engage the Professional Services or NetApp.
Um yes I can:
Not sure that will help though. Seems odd that nobody can just look at the picture and say yes or no...
Run the config advisor, it will help no doubt. You will also get a detailed report too what is bad in the environment.
Can you please provide more details which diagram are you referring at ?
The first one that is a photo with the red and blue lines.
The bottom diagram of page 36 has the answer - https://library.netapp.com/ecm/ecm_get_file/ECMM1280392
The only difference is that you only have one disk shelf instead of a stack. Your first picture matches the SAS cables per the diagram in the PDF.
Also run the config advisor, it is always a good tool to run to cross check and verify.
Yes that's correct.
There are 2 factors for doing the SAS cabling :
1) Square goes into Circle
2) Last 2 Ports of the Stack are attached to the controller in reverse order. ( If you have a single disk in the stack you simply reverse it there only).
Hope it helps!
Im looking for SAS cabling of a FAS2220 with 2 controllers to a single DS2246-R5
Any documentation/diagrams to help me understand the best practice for cabling shelf’s
Its laid out pretty clearly in the setup poster for that platform:
Or just follow the diagrams at the top of this thread.
