Real cost of AHV

Hi fellas,Does anyone have a clear answer of what is the real cost of AHV?  I’m told that AHV is free but is this referring to only Nutanix Community Edition? What about AOS? when purchasing a Nutanix node/block/cluster, these come pre-installed but the cluster essentially has no ‘smarts’ without the CVM which is AOS.Referencing this Licensing Quick Reference Guide, it looks like AHV is included with AOS but AOS’ licensing metric is charged per node.  Am I reading this correctly?Is it possible to run AHV without AOS? Thanks,JS

Options for Autoscaling Your Nutanix Cluster in the Cloud

I had made a short video on auto scaling Nutanix cluster in AWS using new Nutanix Playbooks. Playbooks offer a visual way to start automating actions in your hybrid cloud. Due to making the video short, I didn't spend a lot of time talking about options that you could set. Prism central has a lot of alerts that you can use to trigger the action that you want to take. If you don't see the right “Alert” you can customize one of the existing ones to meet your needs and will be a user defined alert. In my example I was using a critical memory capacity over 80% capacity on adding nodes. If your clusters are typically higher than 10 nodes you might try using a higher percentage based on one node is going to be a lower percentage of memory overall. Likewise you could be more aggressive with picking a lower memory percentage. One thing that you'll want to set as well is the “trigger alert if condition persists for". I didn't have it set so I could easily record the demo but I think it would be

Nutanix Support for acquired environment

Hi there community, I’m hoping that someone can give me some guidance. We recently acquired a facility with some Nutanix clusters deployed, and this is my first time working with Nutanix. I have access to the vSphere hosts but no idea on the Nutanix side of things. Trying to activate the support portal with any and all serial numbers I can find just gives me an invalid serial number message….which means I can’t open a support ticket to ask about the serial numbers. I see each of the host machines running a Nutanix Controller VM, but I’m guessing there is a central management console tied to the hardware (NX?), and a spreadsheet from the seller lists some hardware/enclosure serial numbers, but under serial number just mentions refer to PRISM. I’m trying to hunt down someone at the seller to provide more details and make sure things get transferred, but is there anything I can do or look at in the meantime to figure this thing out?

Karbon: Customize kube-let reserved memory

Karbon always allocates 400MB for kube-let and other node resources. However, this is not always enough and kube-let can run out-of-memory when system is under load.When kube-let runs out of memory then we get pods stranded in “Terminating” state and we have to reboot the node. What I did expect was the kube-let terminated pods that got out-of-memory and that kube-let would not run out of memory.Typical 1-1.4MB are reserved at nodes with 16GB memory in other Kubernetes clusters (EKS/AKS/GKE/...)See alsohttps://kubernetes.io/docs/tasks/administer-cluster/reserve-compute-resources/Currently we have added extra nodes and hope that we will not get out-of-memory on any nodes. However, that is not what Kubernetes is designed. Any work-a-round for adjusting the 400MB fixed size reservation?

Restore AHV VM to third party (SAN) vSphere

Hi, We are looking for a solution to restore the VMs running on Nutanix AHV to a vSphere (SAN based) environment. I've heard that HYCU can do backups on ESXi non-nutanix, however is not clear if I can restore VMs running on AHV to ESXi non-Nutanix and vice-versa. If HYCU is not the answer, is there any other vendor that can achieve this goal? Nutanix AHV backup/DR to ESXi non-Nutanix. We need to run the VMs on ESXi non-Nutanix in case of Nutanix/Primary DC failure.

Nutanix Networking in Azure - hybridcloud

 Nutanix’s support for bare-metal is getting close. Please take a look at some of the foundational components for networking in Azure.NCM (Nutanix Clusters on Azure) utilizes Flow Networking to create an overlay network in Azure to ease administration for Nutanix administrators and reduce networking constraints across Cloud vendors.  Flow Networking is used to abstract the Azure native network by creating overlay virtual networks. On the one hand this abstracts the underlying network in Azure, while at the same time, it allows the network substrate (and its associated features and functionalities) to be consistent with the customer’s on-premise Nutanix deployments.You will be able to create new virtual networks (called Virtual Private Clouds or VPCs) within Nutanix, subnets in any address range, including those from the RFC1918 (private) address space and define DHCP, NAT, routing, and security policy right from the familiar Prism Central interface.Flow networking can mask or reduce Cl

Can't get Credential Guard to work

What is the status of Credential Guard on Nutanix VMs? We are running AOA 5.20.I have created a new VM with UEFI, Secure boot and Credential Guard enabled, but I can’t get it to work. Credential Guard is enabled with GPO, but still will not run. When I look at device security, it says “Standard hardware security not supported” and there is no compatible TPM shown in tpm.msc.The OS I’m testing it on is Microsoft Server 2019.

Protecting storage container with local snapshot

I need someone to light my bulb regarding data protection scenario I have in my mind. Currently we're migrating from NetApp/UCS ESX to Nutanix ESX and we uses Commvault as data protection. In addition to Commvault, we uses volume snapshot in NetApp for DR and fast recovery. This does not replicate to remote site however. In Nutanix, I have configured container for Prod and Dev/QA datastores. Prod datastore protected by Commvault intellisnap and keep two day worth of snapshots. DEV/QA datastore does not protected by Commvault due to licensing issue, we would like to use Nutanix data protection to have similar data protection like Prod datastore (2 day snapshots) . My question is, writing script to adding VMs automatically to data protection domain is the only way to go? Or any other suggestion?

VMs on seperate subnets

We have a UTM with 6 interfaces that go to separate subnets. Each subnet has a ToR Switch. The UTM handles the routing. We are installing a new Nutanix 4 node Block and virtualization physical servers. Assuming that we have 6 physical servers and each server is on a separate subnet, what would our network diagram look like if we included the Nutanix Block? Would we need another switch that has the 6 subnets vlanned, ie: 1 connection from the block and then based on the traffic destination send the traffic out through the vlan port to the ToR switch in the destination subnet?

Cascade Lake vs Ice Lake

So i’ve been going through Google searches to find an answer whether Cascade Lake vs Ice Lake can coexist within the same cluster. Unfortunately no luck. So i hope this forum can help me answer this question.My concern is that i was made to understand that Cascade Lake and Ice Lake CPU architecture is different, thus that may pose a performance problems to VM even if the nodes can coexist within the cluster.So the question is, can NX-G7 and NX-G8, which will run on different CPU archtiecture coexist within the same cluster and will it cause any performance issues if this is possible?It would help if you can point me to a KB article or any article for that matter to explain this.Thank you in advance for the help……..

Cluster Docker swarm + Volume Plugin

Hi, I have performed tests of the plugin for integration between Volume Groups in a Nutanix cluster with Dockers containers (https://next.nutanix.com/karbon-kubernetes-orchestration-30/nutanix-dvp-docker-volume-plug-in-25371) and (https://next.nutanix.com/karbon-kubernetes-orchestration-30/docker-nutanix-container-volume-plug-in-18726). While reading the Docker Volume Plugin documentation at (https://portal.nutanix.com/page/documents/solutions/details?targetId=BP-2037-Docker-Containers-on-AHV:BP-2037-Docker-Containers-on-AHV), I did not notice if such a plugin works with Docker containers in swarm mode (Docker swarm cluster). I performed some tests with Ubuntu 20.04, forming a Docker swarm cluster with 03 nodes, all VMs with Nutanix Guest Tools installed.  All the tests using .yml files for the creation of stacks and services, as for the volumes the tests were made both with the command to create the volumes, as well as in the .yml files.

How to get the list of changed data blocks by the API?

I want to backup the Nutanix AHV VMs, ，but I dont’t kown how to get the list of changed data blocks.In this article (Nutanix 5.0 Features Overview (Beyond Marketing) – Part 2), I see the following:Nutanix CBT utilizes the new REST 3.0 API that can be used to query for the changed meta-data regions given any two snapshots of a virtual disk or virtual machine. The approach is valuable for taking incremental and differential backups; and even useful while taking full backups because the API identifies regions that are spare (zeroed), therefore saving on read operations. I read the api documentations (PRISM v2.0 and PRISM v3) carefully, But I don’t see find a useful api.Does anyone tell me which API to use how to use it?Thank you.
