Hi Team..
I'm searching for Best Practice documents regarding the usage space of Aggregate and Volume, but I'm having trouble finding them. I'm curious about the recommended percentage of usage for Aggregate and Volume. Having a link to technical resources would be great.
Please let me know.

I don’t think there is a doc out there that states what you’re looking for. But aggrs at 95% full or higher is what you want to avoid, that is out there in the docs. Typically I tell people@at 75% full you should start planing for what to do with an aggr. ie get more storage. Move data etc.

Where can i find aggrs docs?
I suspect that the cause of the decline in customer service performance is likely due to the volume usage being over 90% and the aggr usage being over 99%.

I’ll look for the 95% doc I was thinking when I get back to my computer. (Been a while since I’ve seen it) But here’s a KB that you might find helpful. https://kb.netapp.com/on-prem/ontap/Perf/Perf-KBs/Performance_impact_due_to_low_aggregate_free_space

Volume capacity won't cause you issues until you hit 100%.
Aggrs at 99% will cause you issues. Much more so if you're still on spinning disk. Personally, I wouldn't run spinning disk aggregates over 80%, but you can run SSD aggregates up to 95% without any performance impact. I don't think there is anything officially documented on that, but those are the recommendations I've heard from NetApp people in Podcasts, at Insight sessions, and on support calls.
