Types of Vservers

A cluster consists of three types of Vservers, which help in managing the cluster and its resources, and the data access to the clients and applications.

A cluster contains the following types of Vservers:

•	Admin Vserver

•	Node Vserver

•	Cluster Vserver

The cluster setup process automatically creates the admin Vserver for the cluster and the node Vserver for each node in the cluster. The admin Vserver represents the cluster, and node Vservers represents the individual nodes of the cluster.

The Cluster Vserver represents the data serving Vservers. After the cluster setup, a cluster administrator must create Cluster Vservers and add volumes to these Vservers to facilitate data access from the cluster. A cluster must have at least one Cluster Vserver to serve data to its clients.

Note: Cluster Vservers are also referred to as data Vservers because they are used to read and write data to and from the cluster. Also, unless the documentation refers specifically to admin Vserver or node Vserver, the term Vserver refers to cluster (data-serving) Vserver.
