Example -- Soft Partitions

Soft partitions could subdivide a disk, c1t1d0s2, into many smaller partitions, each of which could be used for a file system. For example, on a 40Gb disk, you could create 20 2Gb partitions, each of which could be used for a database or a live file system.

Similarly, a logical volume (mirror d10, for example) could be subdivided into multiple smaller pieces.

By creating one large mirror, then soft partitioning the mirror into pieces of appropriate size for your needs, you can keep the overall configuration simple and have maximum flexibility to change the configuration without having to compromise data redundancy.
