We are attempting to isolate our user device MACs from our core network. To faciliate this, we would like to add a layer 3 interface to every user data network and perform DHCP Relay at that point. My question is: what is the controller's capacity to handle DHCP Relay?
Our configuration currently looks like:
2 x 7240s running in master / master via VRRP, ArubaOS 220.127.116.11
12,000 unique concurrent devices
Approximately 500,000 DHCP Requests / day
Thanks for any insight,

I doubt engineering has tested this. If they have numbers it would be real world at a customer site.
I do however have a customer running 7240's with 8-9K unique devices and dhcp relay running on each van without issue. I would start with a baseline of your controllers then add a few DHCP helpers vlans at a time and keep track of the load/processes.
