I am using vRA 7.x with HPSA 10.x. I am using the event broker to call scripts in vRO that end up attaching a software policy[linux] or a patch policy [windows] to a system being provisioned and then remediate that system at time of provisioning. We also use it to apply a configuration policy that is stored in HPSA to the system for further location specific configs also at time of provisioning. We have found it to work really well and efficiently.
