Thank you for the response, Subhajit.
Ok so tiering is not going to be in this configuration, and I should not set a global spare and leave the 1.2TB disk as dynamic? There's no check box or anything like that which designates it dynamic or does simply not having a global spare enable it?
I'm still a little uncertain as to what raid I should go with, they say to have balance between the A/B pools, but with these 600gb and 1.2TB disks its throwing my thought off and I'm constantly going back to the drawing board. What you would recommend?
