I have AFF8080EX with SSD shelves adn I have 5 shelves.
The Ontap versizon is 9.0
There are two SSD aggregates and one SSD aggregate is on one of controllers and the other is on another controller.
Each aggregate has 57 disk (3 raid groups and each has 19 disk, 3 spare)
We want to add one SSD shelf to increase SSD aggregate size.
I plan to do for 12 SSD disk will be on one SSD aggregate and the other 12 will be on the other SSD aggregate to increase SSD aggregate size.
Then each aggregate has 69 disk (3 raid groups and each has 23 disk, 3 spare)
My question here is
1.Do I need to do the volume reallcoation on volume after added disk to the current SSD aggregate? (FOR spinning disk - I agree to do the volume reallocation.)
2.How does the new data R/W to the aggregate after added the new disk to the aggregate?
I was told that the data will be R/W to the new disk in the aggregate until those get even with others and then distribute data to all 69 disk later.
3.If #2 is correct,then I will see the hotspot later on those new disk, am I right? - After disk added to the aggregate, we are building one database which is very busy on R/W.
4.Anyting else that I need to do or pay attention after increase aggregate size?
