Go to the management blade for your NetApp account, and then, from the navigation pane, click Capacity pools.

Click + Add pools to create a new capacity pool.
The New Capacity Pool window appears.Provide the following information for the new capacity pool:
Name
Specify the name for the capacity pool.
The capacity pool name must be unique for each NetApp account.Service level
This field shows the target performance for the capacity pool.
Specify the service level for the capacity pool: Ultra, Premium, or Standard.Size
Specify the size of the capacity pool that you are purchasing.
The minimum capacity pool size is 4 TiB. You can change the size of a capacity pool in 1-TiB increments.QoS
