Being a Supermicro server, I doubt it's a "fakeraid" card O:-)
OTOH, a fakeraid won't see a big disk of 4 TiB, it would detect/treat
each drive separately.

Yes, that tends to be the better approach. Either "ext2" or "ext3" are
the recommended filesystems for GRUB.

Ah, you're right. Then that shouldn't be the problem.
I would try, at first place, to make the required partitions from a
Gparted LiveCD (System Rescue or similar) before installing the system to
see if that helps the installer.
