Learn how to add or remove a node in a Nutanix cluster.
Nutanix clusters are scalable; you can add (Scale Out) or remove (Scale In) nodes in an existing cluster.
This tutorial is designed to help you as much as possible with common tasks. If you are having difficulty performing these actions, please contact a specialized service provider. OVHcloud can't provide you with technical support in this regard.
Requirements

Technical information
With the Hosted Private Cloud solution powered by Nutanix, it is possible to add or remove several nodes when expanding the cluster. However, you must maintain a minimum of 3 nodes, with a maximum of 15 nodes, per cluster for Nutanix on OVHcloud.
The nodes to be added must have the same version of AOS as the existing cluster.
