There is one column per physical disk. This example shows three subdisks that

occupy all of the space on the VM disks. It is also possible for each subdisk in a

striped plex to occupy only a portion of the VM disk, which leaves free space for

other disk management tasks.

Figure 1-16 shows a striped plex with three columns containing subdisks of

different sizes.
