+config MD_RAID10
+ tristate "RAID-10 (mirrored striping) mode (EXPERIMENTAL)"
+ depends on BLK_DEV_MD && EXPERIMENTAL
+ ---help---
+ RAID-10 provides a combination of striping (RAID-0) and
+ mirroring (RAID-1) with easier configuration and more flexable
+ layout.
+ Unlike RAID-0, but like RAID-1, RAID-10 requires all devices to
+ be the same size (or atleast, only as much as the smallest device
+ will be used).
+ RAID-10 provides a variety of layouts that provide different levels
+ of redundancy and performance.
+
+ RAID-10 requires mdadm-1.7.0 or later, available at:
+
+ ftp://ftp.kernel.org/pub/linux/utils/raid/mdadm/
