Scenario—Soft Partitions

Soft partitions provide tools with which to subdivide larger storage spaces into more managable spaces. For example, in other scenarios (Scenario—RAID 1 Volumes (Mirrors) or Scenario—RAID 5 Volumes), large storage aggregations provided redundant storage of many Gigabytes. However, many possible scenarios would not require so much space—at least at first. Soft partitions allow you to subdivide that storage space into more manageable sections. Each of those sections can have a complete file system. For example, you could create 1000 soft partitions on top of a RAID 1 or RAID 5 volume so that each of your users can have a home directory on a separate file system. If a user needs more space, simply expand the soft partition.
