“Example of a Striped Plex with One Subdisk per Column” on page 23 shows a striped

plex with three equal sized, single-subdisk columns. 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.
