I am somewhat new to the storage game and working for a new company that recently bought a FAS2750 and 1 additional disk shelf.
I am trying to get our system set up in the best way and can't seem to get use out a large chunk of our disks.
The FAS2750 has 24 1.64TB disks.
the Disk shelf has 12 7.15TB disks.
When I look at my disk summary, it says that i have 85.67TB of spare disk space.
As far i understand I would need to place the disk shelf disks into a different aggregate because the are different sized disks from the ones in the controller unit. I can't seem to figure out how to get the existing aggregates to let go of these disks so that I can add them to their own aggregate. Is that even the best thing to do with the spare disks?
Please let me know if I should elaborate on anything.
With that config, I typically do all the "internal" (1.64T drives) aggr for controller 01. And the 1.8 drives as an aggr (+1 spare) on controller 02. It's not a 50/50 match, but it's probably the simplest way to do it.
There's other options though. You can mix drives inside an aggr. So you can have 1 raid group of 1.67 drives and one of 1.8. but that would make it all on one controller.
