Hi,
  i want to  select 4(600G) local disks combined with  3*800G disks form
diskarray  in one datanode.
  is there any problem? performance ?

If you use any sort of RAID-0, you may effectively either lose 200GB from
the larger disks or lose significant performance from the disk array.

Make sure that the striping is significantly long.  The default for most
RAID setups is too short.
