Install Proxmox DELL R710

Please suggest which version I have to setup perfectly .
The current one of course!

Is that the only question? Then you are really lucky :-)

Usually handling an present hardware Raid controller (PERC, H310, H710, ...) triggers more questions. (You did not state if you have something like that.) As I am a ZFS user I recommend to flash/switch it to "IT-Mode" and use ZFS. Other users may recommend "use that controller as intended and do not use ZFS". The unquestionable point is: do not use ZFS with hardware Raid.
In any case the most important point: have fun! :-)
