The highest capacity drive that was validated is a 4TB unit. I have a few unvalidated 8TB drives attached to that same controller in an R710. I can't speak to the power piece (though I would imagine it's fine), but 6 drives won't be an issue for the PERC. I would still recommend making sure that your PERC firmware is up to the latest, however.
