install windows 2012 r2 on dell poweredge r720 - where's the suu iso?

hi, next week I will face the task of installing w2k12 r2 on a poweredge r720. it should be a complete new installation. i however can't seem to find a system management tools dvd that contains a suu that can be used to deploy w2k12 r2. the newest i found is this http://www.dell.com/support/drivers/us/en/19/driverdetails?driverid=cmy20 and as one can see in the compatibility section this version is not compatible with windows 2012 r2. is there a clean way to setup windows 2012 r2 on a poweredge r720? kind regards Michal Piatek
