There has been lot of things need to be consider while configuring an Aggregate, whenever I build a new filer I use to follow the below best practices for creating the aggregates. Ref: TR3838. This is the official NetApp position on RG sizing.
64-Bit Aggregate
32-Bit AggregateIn Data ONTAP 7.2.x and earlier, parity drives and physical drive size are included in the 16TB limit for 32-bit aggregates.
In Data ONTAP 7.3.x and 8.0.x, only data drives and usable drive capacity are included in the 16TB limit for 32-bit aggregates.
It’s not necessary to use the default RAID group size (14+2=16) in all the cases, because everything is depends on your current infrastructure configuration.
