The system default for the number of children data is being striped across is
two. Therefore, you only need to specify the number of children for
numbers greater than two.
Example:
If you are working in
a V-Switch cluster,
this volume must be
configured on both
V-Switches.
In Figure 46, page 99, a striped volume, Stripe 1, is created across four
children: Simple 2, Simple 4, Simple 8 and Simple 10. The striped unit size
is 100 blocks, meaning that in each read/write function, 100 blocks of data
are read/written into Simple 2; then 100 blocks into Simple 4;. then 100
blocks into Simple 8; then 100 blocks into Simple 10 and then back again to
100 blocks in Simple 2 until the end of the data chunk.
