Nutanix clusters are scalable. You can add nodes to an existing cluster.
This guide will show you how to add a node and ensure it works properly.
OVHcloud provides services for which you are responsible, with regard to their configuration and management. You are therefore responsible for ensuring they function correctly.
Requirements
- A Nutanix cluster in your OVHcloud account
- Access to the OVHcloud Control Panel
- You must be connected to the cluster via Prism Central
- A ready-to-configure physical server added to the OVHcloud Control Panel
