Vsphere 5.1 + Storage appliance + APC

Hi guys anyone configured APC with HA and storage appliance?

I found the "PowerChute Network Shutdown in an HA Cluster, see Clean Shutdown of Virtual Machines using PowerChute Network Shutdown in a HA Cluster Environment." but does this work with the storage appliance HA configuration?

Also what is the proper way of shutting down the Cluster with VSA? 

Thank you
