[CentOS] raid 5 install

Hello list.

The next days we are going to install Centos 7 on a new server, with 
4*3Tb sata hdd as raid-5. We will use the graphical interface to install 
and set up raid.

Do I have to consider anything before installation, because the disks 
are very large?

Does the graphical use the parted to set/format the raid?

I hope the above make sense.

Thank you in advance.

Nikos
