VxVM supports the combination of mirroring above striping. The combined layout is called a mirrored-stripe layout. A mirrored-stripe layout offers the dual benefits of striping to spread data across multiple disks, while mirroring provides redundancy of data.
For mirroring above striping to be effective, the striped plex and its mirrors must be allocated from separate disks.
Figure: Mirrored-stripe volume laid out on six disks shows an example where two plexes, each striped across three disks, are attached as mirrors to the same volume to create a mirrored-stripe volume.
The layout type of the data plexes in a mirror can be concatenated or striped. Even if only one is striped, the volume is still termed a mirrored-stripe volume. If they are all concatenated, the volume is termed a mirrored-concatenated volume.
