Interpret fdisk output for HPE ProLiant ML350

I am a newly baked server owner and I bought the above mentioned model which nominally has 4*1.2TB of physical disks. I was wondering if my amateurish ubuntu installation "caught" them all. I have however some trouble interpreting the output of fdisk:

Could you elucidate me?

Thanks!
