Hello @DoHuuBa,

AO generally will not impact the performance. It will increase the performance of lower tier volumes considerably. In this case, reason for performance issue could be something else. Can you please provide below details to undertsand the issue better:

Can you please provide more details about the performance issue you are facing after started using AO?
When the customer has started using AO?
What was the performance measure before AO and after AO?
What is customer's exact observation about the performance after AO?
Are there any particular volumes or a CPG facing performance issue? - If yes, please provide the volume/CPG name?

Also please provide the below command outputs:
showaocfg
showcpg
showcpg -s
showcpg -sdg
showpd

Hello DoHuuba,

 

This obviously looks to be a certification question

The answer is D - This is not a recommended AO configuration (using SSD as Tier 0 and NL as Tier 1) since the performance differential is too high.

You can either use SSD for T0 and FC for T1 or FC for T0 and NL for T1 in a two tier configuration.
