Disk aggregation

Disk aggregation is the abstraction of two or more hard disks, disk partitions, or other logical volumes into a single logical disk.^[1]

This is done to:

• create a single logical disk with a capacity larger than any of the available physical disks
• provide a simple way to increase disk performance
• provide a simple way to implement LUN-level storage virtualization
