See also subdisk volume

A copy of a volume and its data in the form of an ordered collection of subdisks. Each plex is a copy of the volume with which it is associated. The terms mirror and plex can be used synonymously.

A duplicate copy of a volume and its data (in the form of an ordered collection of subdisks). Each plex is one copy of a volume with which the plex is associated. The terms mirror and plex can be used synonymously.

A copy of a volume and its data. There can be several plexes per volume. The terms mirror and plex are used synonymously.

A plex is a logical grouping of subdisks that creates an area of disk space independent of physical disk size or other restrictions. Mirroring is set up by creating multiple data plexes for a single volume. Each data plex in a mirrored volume contains an identical copy of the volume data. Plexes may also be created to represent concatenated, striped and RAID-5 volume layouts, and to store volume logs.

A plex refers to an instance of the volume. Mirrored volumes have two or more plexes. All other volumes have one plex.

Plexes, columns, and subdisks are the constituent parts of the volume.
