NCP Cluster Deployment and Configuration

Question 1

What must be done before cluster creation?

Accepted Answer

Image nodes with Foundation

Answer

Before a Nutanix cluster can be created, the physical nodes must be imaged with the necessary software, including the chosen hypervisor (e.g., AHV, ESXi) and the Nutanix Controller VM (CVM). This imaging process is efficiently performed using Nutanix Foundation, which automates the installation and configuration of these components on each node.

Question 2

Which tool simplifies initial cluster deployment?

Accepted Answer

Foundation

Answer

Nutanix Foundation is the dedicated tool designed to simplify and automate the initial deployment and imaging of Nutanix nodes. It streamlines the process of installing the hypervisor and the Nutanix software stack (CVM) onto new hardware, making cluster creation efficient and straightforward for administrators.

Question 3

How is a Nutanix cluster IP assigned?

Accepted Answer

Cluster Virtual IP (VIP)

Answer

A Nutanix cluster is assigned a Cluster Virtual IP (VIP) that serves as a single, highly available access point for management. This VIP floats between the Controller VMs (CVMs) in the cluster, ensuring that the management interface remains accessible even if an individual CVM fails. It is used for accessing Prism Element and other cluster-wide services.

Question 4

Which method adds a node to an existing cluster?

Accepted Answer

Use Prism's Expand Cluster feature

Answer

To add a new node to an existing Nutanix cluster, the most efficient and recommended method is to use the 'Expand Cluster' feature within the Prism Element web console. This wizard-driven process automates the discovery, imaging (if necessary), and seamless integration of the new node into the cluster, ensuring proper configuration and data rebalancing.

Question 5

What is required for node discovery during deployment?

Accepted Answer

Same subnet configuration

Answer

For Nutanix Foundation to successfully discover and image nodes during deployment, all nodes and the Foundation instance must reside on the same broadcast domain or subnet. This network configuration allows Foundation to communicate with the nodes via ARP and other discovery protocols, enabling the automated imaging and cluster creation process.
