Hi,
We had an performance issues on a FAS2240 netapp storage. After reduce the aggregate from 92% to 85% issues have gone. Want to ask experts where can I find the recommended maximum limit of use of aggregate for netapp 2240 storage? Please, I need to read it on an official documentation from netapp.
Thanks.

netapp does not like to communicate such information but afaik on recent netaps, you'll see a performance hit around 85% and the hit will become drastic somewhere between 90 and 95

this is expected with any modern recent filesystem with proper replication and snapshoting abilities and self defrag or dragmentless design. note that other vendors ( and i think netap previously ) simply choose to limit the available space. noawadays many people think cost per available space ( and for some reason some still choose netapp ) so they'd rather look cheaper and deal with the customer's frustration later on

sorry that was not too helpful but i really do not think you are likely to find anything explicit in netapp's docs. there are traces on the forums though
