Usually this is for 12x 3TB raid-10 arrays that yield ~18TB of usable space before formatting.
With ext4 we would use about 400gb of space.
Simply do:
yum install xfsprogs xfsdump
That will install xfs filesystem. Then simply format the drive as you normally do:
mkfs.xfs /dev/sdb1
and that will format it with xfs
add it to fstab, and your all set.
To partition the drive, please see our GPT partition guide using parted.
