I use ONTAP version 9.70P9, and only saw the automatic creation of aggregations, and the system automatically created two aggregations for me. But I heard from friends that when the number of disks is small, "ADP" can be used to get more space. But I did not find how to use ADP in GUI (browser). Is consloe required to configure ADP? Also, as mentioned above, if it is 12 * 1.8TB SAS, how much free space can I get after using ADP? How about using automatic aggregation? Thank you very much and I wish you a happy day!
ADP is created upon initialization of the HA pair. There’s nothing to really configure in the GUI.
it will partition disks out to either root-data or root-data-data configurations. RD is typical on FAS and RDD is typically on AFF. The root is much smaller than the data parts. You can actually look up on huw.NetApp.com and see sizes based on your model and drive count.
you can run “storage disk show -partition-ownership”
and it will show the partitions and which controller owns them.
