  As far as I know, the CentOS installer didn't allow a RAID 1+0 during 
install! But, I think you can setup this using RAID1 + LVM :
   - Setup md0 (Raid1) (sda,sdb)
   - Setup md1 (Raid1) (sdc,sdd)
   - Setup LVM (md0+md1)
 
  Or you can try install CentOS on another drive, and the setup the RAID1+0 and
migrate the install to it.
