LSI 9260-8i. How to make scalable RAID?


I have LSI 9260-8i + SAS Expander RES2SV240.
My current scheme of connection HDDs.

My goal: create Raid array and make large logical disk D:<br />It will be 63TB on start and I plan to expand it by adding new HDDs through expander.
My current LSI config utility.

Is it good idea?

I have WD Gold hdds.

I can setup timing using smartctl, but after shut down system these settings lost.
Does LSI make time settings or I need to setup time each time when OS start?
