Given the constraint of a 16-port switch for a 20-node cluster, the consultant cannot physically connect all nodes to the network simultaneously. VLAN tagging allows multiple virtual networks to be carried over the same physical network. However, the challenge here is not about VLANs but the physical limitation of ports. The practical approach would be to manually create the cluster, potentially in stages, as the full network capacity required for all nodes is not available.References:

When changing VLAN configurations for hosts and Controller Virtual Machines (CVMs) in a Nutanix cluster, doing so while the cluster is running can result in temporary communication losses, leading to alerts such as a node appearing down. To avoid these disruptions and ensure a smooth reconfiguration process, it is advisable to stop the cluster services before making VLAN changes. This prevents the cluster from detecting intermittent connectivity as node failures, thereby avoiding false alerts in Prism Element.

In preparing for the VMware NSX security project, the administrator should consider the network infrastructure and how the NSX will interact with the existing Nutanix environment. VMware NSX requires the use of VMware Distributed Virtual Switches. In the given scenario, where the CVM (Controller Virtual Machine) network is segmented and storage-only nodes are not present, the key step is to ensure that the network settings are compatible with NSX. Disabling the CVM network segmentation allows for a unified network that supports the requirements of NSX for network virtualization and security, making it the crucial first step before any further NSX-specific configurations are applied.References: Nutanix Bible, Nutanix Community discussions, VMware NSX documentation.
