Nutanix products network port diagrams

I spent some time to produce small Visio with Nutanix ports diagram to visualize the interaction between Nutanix software components (CVM, Prism Central), hardware (SuperMicro IPMI – it is remote management console like HP iLO, Dell DRAC) and hypervisor (in this case VMware ESXi and Nutanix Acropolis hypervisor AHV). Some of you might ask, where is vCenter or SCVMM? Well, Nutanix doesn’t need to “talk” to vCenter or SCVMM in order to run :-), we do not rely on vCenter or SCVMM at all. What we need is, talk to the hypervisor, in this case, ESXi, AHV and Hyper-V – all three supported by Nutanix. Communication between CVM and VMware ESXi, Nutanix AHV flys over SSH that’s why when you run Nutanix you can’t disable SSH on either ESXi or AHV.

Components on the diagrams:

  • CVM – controller VM – the distributed brain of Nutanix solution, the core of the web-scale.
  • Foundation – Nutanix provisioning tool. It does provision and configures automatically CVM and hypervisor as well as creates a Nutanix cluster, creates a storage pool, container and mount container into ESXi as datastore. check my two-part series about Nutanix Foundation
  • Prism Central –  customers can manage many Nutanix clusters across many locations from a single pane of glass using the simple and intuitive Nutanix Prism Central interface. Read more about Prism Central.
  • IPMI – remote management console like HP iLO, Dell DRAC but for SuperMicro servers. I used to work with iLO and DRAC and must say IPMI is far faster form those two mentioned.
  • ESXi – hypervisor
  • AHV – Acropolis Hypervisor
  • Hyper-v – Microsoft Hyper-V 2012R2
  • XenServer – Citrix XenServer 7.X
  • Azure and AWS – Nutanix supports public cloud providers as a target for backup and DR
  • Administrator – it is Admin workstation
  • Nutanix Files – File Server
  • Files Analytics – analytics VM for Nutanix Files
  • Prism Central – Nutanix Prism Central
  • vCenter – VMware vSphere vCenter
  • SCVMM – Microsoft Virtual Machine Manager
  • Nutanix Move (formerly know as Xtract) – Nutanix migration tool to Nutanix AHV
  • KMS – Key Management System
  • CALM – Nutanix Cloud Automation Lifecycle Management
  • Karbon – Nutanix Kubernetes
  • Nutanix ERA – database as a service
  • Nutanix Flow – Nutanix native microsegmentation
  • Nutnaix Leap – Nutanix DR automation and orchestration

Artur, since SSH needs to be opened on the ESXi hosts for communication between CVM and ESXi, would it not be a good idea to set the UserVars.SupressShellWarning to 1 on all ESXi hosts?
Otherwise you get a warning in vCenter for something that is required.
Could this be also included in Foundation?

Superkikim

Hey. Tx for the great work. These diagrams are awesome. There a mistake on the link to download the AHV port diagram. It points to the ESXi one.

Also, it seems that port 2074 is missing on the AHV diagram. It allows communication between NGT and the CVM.

Cheers

Akim

Great work Artur! This has to be worth another Renaissance trip :0

Chris

Hey, great job done here! Would it be possible to get the Visio-Files somehow?

John Adkison

I have one line of communication for you to add between Prism Central and the CVMs. I identified that the Capacity tab of a cluster would not show any data until my firewall team opened-up SSH communication between the Prism Central system and the CVMs.

crim

A couple notes on the AHV diagram:

– The Global Catalog port is port 3268, not 3286
– May consider adding TCP port 2020 (Cerebro) to the CVM communication to Administrator. This is used for DR
– May consider adding TCP port 2016 for Pithos to the CVM communication to Administrator.
– May consider adding TCP port 2011 for Chronos to the CVM communication to Administrator.

Chris

Really great diagrams!

It would be perfect it the Visio Files were downloadable too, so we Consultants could put, e.g. hostnames to the boxes or include just those optional connections which are indeed used at the respective customer’s implementation.

Would it be possible for you to also do diagrams for Metro Availability and its Witness?

Dan Prince

I just recently installed AOS 5.5 on ESXi 6.5 hosts and received a warning message regarding 3rd party IO filter storage provider failing. The fix was to open port 9080 between the hosts and the vCenter. So maybe add that port to the ESXi diagram.

Amauri Costa

Sensational!!! Nutanix every day much better and unreachable!

Philip

Really very helpful information. Thank you very much!
