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.

Noticing a potential typo or error in the DNS server IP address notation:

D. New IPs provided should be verified to not conflict with the customer ' s network : It ' s crucial to verify the accuracy and validity of the IP addresses provided, ensuring there are no typos and that the IPs do not conflict with existing network configurations. The noted IP ' 192.1685.20 ' appears to be incorrectly formatted and should be corrected and validated.

Nutanix best practices require:

CVM and AHV hosts to be on the same VLAN for seamless internal communication.

IPMI (Out-of-Band Management) on a separate VLAN to isolate management traffic.

Before going on-site to deploy a Nutanix cluster, the following prerequisites are crucial:

A. Complete the kickoff call and validate the BOM (Bill of Materials) : This ensures that all necessary components are accounted for and any discrepancies or missing items are addressed prior to installation.

C. Validate whether the cluster questionnaire is complete and if the physical switch configurations are complete : Ensuring that all relevant customer and network information is obtained and validated is critical to avoid delays or issues during the physical installation and configuration of the cluster.

When preparing the laptop and Foundation networking for the installation on customer-indicated HPE/OEM hardware, the consultant should set IP addresses in both the CVM/Host and IPMI subnets (Option C) This ensures that all necessary network interfaces are appropriately configured for management and operational traffic, facilitating seamless communication during the foundation process. Properly setting up IP addresses in both subnets is crucial for ensuring that the Foundation process can access both the CVMs/Hosts and the IPMI for management tasks.

If there is no connectivity between the Foundation VM (FVM) and the consultant ' s laptop despite all devices being properly powered and correctly configured, the likely cause is the desktop firewall on the consultant’s laptop blocking ping requests. This is a common issue that can prevent communication over the network even when all other network configurations are correct. The consultant should check the firewall settings and allow the necessary permissions for network communications to establish connectivity.
