Planning RAID Storage for the Xserve RAID System 69
RAID 0+1 and RAID 10 Schemes
On the Xserve RAID system, RAID 0+1 is a stripe of mirrored pairs. An example of this
configuration is shown at the top of the illustration below.
Using a combination of the hardware controller and software, you configure the system using
RAID 10 with two drive modules on each controller. The drive modules on each side can be
either striped together or mirrored.
