You can't install centos (or redhat) over a gpt partition (unless
itanium platform) and there is a big chance your bios won't boot such
installation. I came with 2 solutions: if disk access performance
isn't important (as for backup), I do software raid; or I install two
little raid1 disks for the OS and then I use GPT or LVM on the
multi-tera raid of big disks.
Or partition the array with a small partition for OS and big partition (gpt)
for data. You should be able to carve up the array that way.
I think you're mixing your terminology there. gpt isn't a partition type,
it's a disklabel. There's only one per disk (obviously), no matter how
many partitions are on the disk.
What some array controllers can do is carve a single array into multiple
volumes (usually each presented on their own LUN). Then you could carve
the one array into a small boot volume (with an msdos disklabel and
multiple partitions) on one LUN and the rest in a large data bolume (with
a gpt disklabel) on the other LUN.
