When installing a Nutanix cluster on hardware servers pre-loaded with an existing operating system such as DiscoverOS, the best approach is to re-image the bare metal nodes. This process involves using the Nutanix Foundation tool to install the required Nutanix software (such as AOS and Hypervisor) onto the nodes, replacing any pre-existing software. This ensures that the hardware is properly configured and optimized for the Nutanix environment.References:

According to Nutanix best practices for network configuration, it is recommended to use either:
* 10G uplinks only: This provides sufficient bandwidth for typical data center operations.
* 25G uplinks only: This option is suitable for higher bandwidth requirements. Mixing uplinks with different speeds, such as 10G and 25G, is not recommended as it can lead to non-optimal performance and complexity in handling traffic.

Prior to the initial base system setup for a new cluster installation, the consultant needs to document several critical infrastructure details. Among the most important are the DNS and NTP IP addresses (C). These addresses are crucial because they ensure that all nodes within the cluster can resolve domain names properly and synchronize their clocks accurately, which is vital for cluster operations and management. Proper DNS and NTP configurations help prevent many common issues related to name resolution and time synchronization that could affect the performance and stability of the cluster.References: Nutanix Installation Prep Guide, Nutanix Network Configuration Requirements.
