New FAS2620 with Ontap 9.1 being installed and there are total of 36 x 4TB SATA drives which I would like to maximize storage capacity. It seems like the internal drives were root-data partitioned already from factory. My question I have is, when creating a new aggregate is it advisable to mix root-data partitioned disks with data-only drives and create one aggregate assign to one node (obvisouly this will create two different size of disk/partion raid group as data-only partion disks will have larger partition)? or root-data parition ALL of the drives and create one aggregate assign to one node?
