ADP still limited to internal disks on FAS26XX with Ontap 9.2?

Just trying to confirm that ADP is still only supported on the internal disks (those in the the shelf with the nodes) on the FAS26XX series running Ontap 9.2? I can't track it down in the docs.

 

Thanks!

Ok - I have clarified the situation with our TME team - Only the FAS2650 supports ADPv1 on an external shelf of NL-SAS drives if and only if the internal slots are empty. Additional shelves added to a system with internal drives are not partitioned.

 

The NL-SAS drives that we have available are all large form factor (LFF), while the internal shelf on a FAS2650 is small form factor (SFF), and we do not have a FAS2240-4/2554 type of system with controllers in a 24-slot LFF shelf in our most recent generation of hardware, therefore there may be a desire under some situations to deploy one with only "external" drives, and it is of course desirable to have them partitioned for the root aggregates.

 

The FAS2620 does not have this behavior, as it is a LFF 12-slot enclosure, but we also have SAS and SSD SFF drives in a LFF carrier to fit in it, so the internal slots can be used for the root partition under any of these configs.

 

Hope this helps!
