Volume Layout

The layout that is used to map the volume.

Concatenated

A volume whose data is organized serially and adjacently across components forming one logical storage unit.

Concatenated with copies

A fault tolerant volume that maintains two or three identical copies of the data on different disks.

Striped

A high-performance volume that spreads data in a logical volume across several disk drives in such a way that the I/O capacity of the disk drives can be used in parallel to access data on the logical volume.

Striped with copies

A high-performance redundant volume that spreads data in a logical volume across several disk drives and maintains two or three identical copies on different disks.

Number of Copies
