[Users] Power Management drac5

Hi guys, I've got 3 Dell R710's running as my hypervisors, I'd like to setup power management and the R710's have iDRAC7, can I use the drac5 listed under power management in oVirt? Is there another power management that I should be using instead? Does anyone have any experience with using drac5? Good/Bad? Thanks. Regards. Neil Wilson.
