# Creating spanned arrays

If you want to assign RAID level-x0 to an array, you must create a spanned array.

Note: Spanned arrays are supported only by IBM ServeRAID-4 Ultra160 and ServeRAID-5i Ultra320 SCSI controllers.

Complete the following steps to create one or more identical spanned arrays:

1. In the list of arrays, click the arrays that you want to add to your spanned array.
2. Click >> (Add selected arrays) to add the arrays to the spanned array. You can click >> (Add all arrays) to move all arrays to the spanned array.
3. To create additional spanned arrays, click the New spanned array tab in the right pane.
   Then, repeat steps 1 and 2.
4. Click Next; the "Create logical drives" window opens.

To return to the "Create arrays" window, click Back.
To leave the Configuration wizard, click Cancel.
