Why each option
In clustered Data ONTAP, a data vserver (Storage Virtual Machine) is the logical entity that hosts protocols and volumes and directly exposes data to client hosts.
A high-availability pair is a physical hardware redundancy concept for controller failover and does not itself represent a logical object that exposes data to clients.
The admin vserver is used exclusively for cluster-wide administrative tasks and does not host data volumes or serve client protocols.
A node vserver is a system-internal vserver scoped to a single node for node management purposes and is never used to expose data to external clients.
A data vserver is a secure, isolated logical container that owns volumes, LIFs, and protocol configurations such as NFS, CIFS, iSCSI, and FC. It is the only vserver type designed to serve client data requests. Admin and node vservers exist solely for cluster and node management functions and cannot serve client data.
