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).
