Power Outage Control?

We are running a few CS220 appliances and had a question regarding unplanned power outages and how to handle them. We have big beefy UPSs and our plan is to shut all servers and important appliances when there is X amount of run time remaining. We have configured our servers and it works perfectly but we don't quite know what to do with the CS220s. I've spoken with Support and they say that if there is no I/O on the appliance because the VMs running on the volumes have been shutdown then it is safe to let the appliance go down hard. I'm not a fan of letting hardware go down like that so is there another way to justify doing this? For example, is there a big capacitor which allows for flushing the writers when a controller loses power? Is there some built-in mechanism which prevents data loss/corruption when power is lost?
Thanks in advance.
