“Example of a Striped Plex with Concatenated Subdisks per Column” on page 24
illustrates a striped plex with three columns containing subdisks of different sizes. Each
column contains a different number of subdisks. There is one column per physical disk.
Striped plexes can be created by using a single subdisk from each of the VM disks being
striped across. It is also possible to allocate space from different regions of the same disk
or from another disk (for example, if the size of the plex is increased). Columns can also
contain subdisks from different VM disks.

See “Creating a Striped Volume” on page 214 for information on how to create a striped
volume.
