Maybe I'm just being an idiot, but I couldn't seem to find best practices that describe max directory depth and size. I know anecdotally directories shouldn't be larger than 10mb (the directory itself, not the contents) but I can't seem to find an official best practice guide that has these. Can anyone point me to the right doc?
Thanks in advance, Nick

Nick,
You're not going to find an official guide on this topic, but here's what I found in the Netapp forums after having similar questions:

There's nothing official, because it depends how the environment..mostly application, is built around a high file count problem.
Ive helped customers manage systems with 5B files & directories on a single system, but how the filesystem was used by the application layer..was critical in this working...or not.
Local disk or not, you dont want huge directory structures.

Hi Nicholas,
https://kb.netapp.com/support/index?page=content&id=3011562
The maxdirsize default is 1% of the systems physical memory. We have millions of files in one directory (NFS)and increased the maxdirsize (nearly doubled).The maxdirsize should not be greater than 3% of the filers systems physical memory! Then you run in lots of problems and all protocolls are affected. We bought a new Filer with more RAM and split the Million Files (38 Mio.!) into subdirectories ;)
You can check the current size with "slist PATH" (e.g. PATH = /vol1/.....)

Revert the maxdirsize to a smaller Value: https://kb.netapp.com/support/index?page=content&id=3011980
