48 Understanding RAID Concepts
NOTE: On the PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di controllers, there are
special considerations when implementing RAID 50 on a disk group that has disks
of different sizes. For more information, see Considerations for RAID 10 and 50 on
PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di.

RAID Level 60 (Striping over RAID 6 sets)
RAID 60 is striping over more than one span of physical disks that are
configured as a RAID 6. For example, a RAID 6 disk group that is
implemented with four physical disks and then continues on with a disk
group of four more physical disks would be a RAID 60.
