Dell PowerVault ME4 Series Storage System Administrator’s Guide

Adding linear disk groups

The system supports a maximum of 64 pools and disk groups. Whenever you add a linear disk group, you also automatically add a new linear pool. You cannot add further disk groups to a linear pool. However, you can expand storage by adding disks and dedicated spares to existing linear disk groups.

All of the disks in a linear disk group must share the same classification, which is determined by disk type, size, and speed. This provides consistent performance for the data being accessed on that disk group. When you delete a linear disk group, the contained volumes are automatically deleted. The disks that compose that linear disk group are then available to be used for other purposes.
