cDOT -> Clustered Data ONTAP can run in a "single" node can run in a two-node can run in an even numbered nodes (up to 24, provided it is an approved config)
cDOT is an expandable OS that is the future of ONTAP. If you look at 8.3, there is *NO* 7-mode release at all. All new developments are on Clustered mode.
It also gives you a single, Global Namespace. In 7-mode, you essentially would manage (from a protocol perspective) two nodes. cDOT allows control for protocol to/from all nodes simultaneously.

On top of that cDOT also allows you to throttle workloads using the built-in QoS functionality by specifying either a max throughput value (MB/s or IOPS) per policy (which can then be applied to a multiple volumes

Because 7-mode is deprecated....
