Integrated Striping Description
On Integrated Striping volumes, the firmware writes data across multiple disks instead of
onto one disk by partitioning each disk’s storage space into 64-KB stripes. The firmware
interleaves the stripes in such a way that the combined storage space consists alternately
of stripes from each disk.
The following figure shows an example of Integrated Striping. In this example, the
firmware writes segment 1 to disk 1, segment 2 to disk 2, segment 3 to disk 3, and so on.
When the firmware reaches the end of the disk list, it continues writing data at the next
available segment of disk 1.
