Power 9 disk config


I am configuring a new power 9 for a customer a 9009-41A

This system has a maximum of 10 internal drives.

Requirement is for;

4 x 931GB SSD in RAID10
4 x 283GB SAS in RAID5

I am trying to determine if there is a possibility of a performance issue
between the two raid sets ?

My concern was raised when I got an email from IBM with "You will not get
any performance guarantees!"

Customer is requesting the SSD's in RAID10.

I know there are a number of BP's on this list - any comments on this disk
config ?

Thank you
