NTER. The Sub-Array Selection screen opens.
The controller displays the number of available sub-arrays you can choose
from. In this example, the first one is a single sub-array that provides nine
data drives and one parity drive, and the second example is two sub-arrays
that provides two four-drive sub-arrays with one parity drive.
When you create a redundant array, such as a RAID 5 or 50 type, you will
always be creating at least one sub-array comprised of the data drives and
one parity drive. When a sufficient number of drives have been selected
you can choose to make multiple sub-arrays of your array. This provides
the benefits of a quicker recovery from a drive failure since only one of
the smaller sub-arrays is affected.
Tips & Tricks If this is just one single array with less than five hard drives,
choose the default of one sub-array.
