Nutanix network port diagram

Nutanix network port diagram

I spent some time to produce small Visio with Nutanix ports diagram to visualize 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 don’t need to “talk” to vCenter or SCVMM in order to run :-), we do not relay on vCenter or SCVMM at all. What we need is, talk to hypervisor, in this case ESXi, AHV and Hyper-V – all three supported by Nutanix. Communication between CVM and VMware ESXi, Nutanix AHV fly over SSH that’s why when you run Nutanix you can’t disable SSH on either ESXi or AHV.

Components on the diagram:

  • CVM – controller VM – the distributed brain of Nutanix solution, the core of the web-scale.
  • Foundation – Nutanix provisioning tool. It does provision and configure automatically CVM and hypervisor as well as create Nutanix cluster, create 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 target for backup and DR
  • Administrator – it is Admin workstation
  • AFS – Acropolis File Server

    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?

    • Thanks for comment Lieven, very good suggestion. I will ask PM if they can included this as a part of provisioning process.

  • 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.

    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.

    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.

    • Thanks for feedback. I will update Global Catalog ports within few days. Port 2020 is listed on different (for DR) port diagram.
      I do not list specific processes (like Pithos, Cerebro and so on) on diagrams as those are not essential for day to day administration.
