Hey Jeff,
Not sure what you mean by "run vROps Horizon for VDI", but if you have 7.5 installed of vROps you can use the V4H Management Pack that connects to a Broker Agent which needs to be installed on one of your Connect Servers. You can check compatibility here - VMware Interop Tool
Hope this helps!
P.S. If you have multiple View Pods, you'll need a Broker Agent per pod pointed to a separate V4H Adapter Instance in vROps (i.e. 2 View Pods == 2 Broker Agents == 2 Adapter Instances).
