FIGURE F-2 RAID 1 Arrays

RAID 1 Enhanced Arrays

A RAID 1 Enhanced (RAID 1E) array—also referred to as a striped mirror—is similar

to a RAID 1 array except that data is both mirrored and striped, and more disk drives

can be included. A RAID 1E array can be built from three or more disk drives.

In this figure, the large bold numbers represent the striped data, and the smaller,

non-bold numbers represent the mirrored data stripes.
