Striping Across Three Columns
A stripe consists of the set of stripe units at the same positions across all columns. In the
figure, stripe units 1, 2, and 3 constitute a single stripe.
Viewed in sequence, the first stripe consists of:
◆ stripe unit 1 in column 0
◆ stripe unit 2 in column 1
◆ stripe unit 3 in column 2
The second stripe consists of:
◆ stripe unit 4 in column 0
◆ stripe unit 5 in column 1
◆ stripe unit 6 in column 2
Striping continues for the length of the columns (if all columns are the same length), or
until the end of the shortest column is reached. Any space remaining at the end of
subdisks in longer columns becomes unused space.
