## Express Array Configuration

The Express Configuration button from the Array Management Individual Configuration page displays novice-level array configuration setting options. When you choose to express-configure an individual array, you can type a text description of the array, add disk drive trays to an existing storage profile, or change the characteristics of an existing profile.

When you change an existing profile to a new profile, the existing profile's settings (such as cache settings) are copied to the new profile and the existing profile is deleted. You can select the number of drives from a tray to add to the profile.

Caution - When you change an existing profile, data found on any detected volumes is deleted.

### About Creating Storage Pools and Configuring Arrays

If you select Express Configuration (available by clicking Array Management page > Individual Configuration button > Express Configuration button) and perform the following:

- Click Add Storage to Profile
- Select all drives in a fully-populated tray

then two storage pools are created by default.

If you select less than the total number for available drives or the tray is not fully populated with drives, then one storage pool is created.

For more control over the number of pools created per tray, for example one storage pool per tray, use the Manage Pools feature available from the Custom Configuration page (available by clicking Array Management page > Individual Configuration button > Custom Configuration button).
