Why each option
In clustered ONTAP, a node is defined as a single storage controller, which is the fundamental physical building block of the cluster architecture.
An HA pair is a grouping of two nodes configured for high availability failover, not a single node itself.
A node in clustered ONTAP is a single storage controller that independently runs ONTAP software and manages its assigned disks, network ports, and resources. Nodes are paired into HA pairs for redundancy and failover, but the node itself refers to the individual controller unit. This distinction is foundational to understanding how clustered ONTAP scales and how storage resources are organized.
A data Vserver (SVM) is a logical data-serving entity that exists above the node layer and spans one or more nodes.
A data port is a physical or logical network interface on a node used for client connectivity, not the node itself.
