Every communication device in the world needs network ports number to communicate with other devices interconnected in the network.
Nutanix Controller VM CVM has predefined reserved networking ports number for inter and outer communication with CVM , Hypervisor –AHV, VMware Esxi, Hyper-V etc.
Therefore Nutanix Controller VM CVM has own ports list for CVM to CVM communication in Nutanix Cluster.
Network ports are using by Nutanix cluster components, Controller VM (CVM) and AHV or other supported hypervisors for communicate with each other using networking ports to sharing information to work in designed architecture.
Nutanix HCI is designed with many cluster components and services to invent the hyper-converged architecture to run any type of production workload on Nutanix cluster.
Ports for external access to CVMs
These externsl networking ports are using by Nutanix Controller VM CVM for external access of Nutanix CVM from outside of the cluster.
| Port(s) | Reserved For |
|---|---|
| 2009 and 2020 | Remote site replication |
| 2100 | Cluster and IP address configuration |
| 2010 | Curator |
| 80 or 8443 | Remote support tunnel (outgoing connection to service centers nsc01.nutanix.net and nsc02.nutanix.net) |
