Originally I tried to simply upgrade an older server with more drive space, I installed six (6) 4TB drives and did a new CentOS 6.5 install but the OS would not allow me to configure more than 2TB per drive.
Subsequent research leads me to conclude that if the bios supports UEFI and the installer boots as such then the installer should see 4TB drives without any issues. I'm also assuming that any server I order today (i.e. a more modern server) should ship with UEFI support in the bios.
anaconda's installation time partitioning tool doesn't support GPT format disks, as far as I know.
if you boot to a shell prompt, and use gparted and the lvw commands to setup the disks the way you want, making sure /boot is in the first terabyte of the drive, then you should be able to install to those existing partitions/lvs...
