The make and model of the systems should be verified during the Tech Review Call. This step is essential to ensure that all necessary information is collected and verified before any physical interaction with the hardware. Verifying these details during the call helps in preparing adequately for the cluster deployment, allowing the consultant to anticipate and mitigate any compatibility or configuration issues before arriving onsite.

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.

If ESXi 6.5 is not available as one of the choices for hypervisor during the Foundation process, the consultant should upload the ESXi image to the specific directory where Foundation expects to find hypervisor images. The correct path for this operation is /home/Nutanix/foundation/isos/hypervisor/esx. This allows the Foundation tool to detect and use the ESXi image for installation on the nodes.

When deploying the latest AOS along with the latest Nutanix hardware, it is essential for the consultant to review multiple sources of information to ensure a successful installation. Release Notes provide details about new features, improvements, and known issues in the latest version of AOS. Software Product Interoperability outlines compatibility between different software versions, ensuring that the AOS and any integrated applications or environments will function correctly. Field & Security Advisories inform about potential security issues and recommended practices to avoid common pitfalls or security risks.

When encountering an error related to unsupported ISO media during the imaging process, and the ISO version is not listed in the whitelist file, the consultant should take several steps to resolve the issue. Replacing and saving the whitelist file in Foundation ensures that the latest compatibility data is used. Downloading the iso_whitelist.json from the Support portal provides the most recent and comprehensive list of supported ISO versions. Editing the whitelist file in Foundation allows the consultant to manually add or update entries to include the ISO in question, ensuring the imaging process can proceed.

When facing connectivity issues between the host workstation and the Foundation VM, ensuring proper network configuration is crucial. Removing and re-importing the Foundation VM can help reset any configuration issues, particularly ensuring that the virtual NIC is set to the correct mode, such as Host-Only, to facilitate direct communication with the host. Confirming the IP addresses and subnet masks ensures that both the host and the VM are on the same network segment, which is essential for successful communication. This step verifies that there are no IP configuration errors causing the connectivity issue.

For a customer to use NIC teaming with the 'Route based on physical NIC load' load balancing option on an ESXi host using a vSphere Standard Switch, they need vCenter Server. This specific load balancing method is not available on a vSphere Standard Switch without vCenter management, as it requires vSphere Distributed Switch capabilities that are managed via vCenter Server. By installing a vCenter server, the customer can upgrade from vSphere Standard to Distributed Switches and access more advanced features including the desired NIC teaming option.
