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……..

How can I add a SAN to the Kubernetes API certificate?

Having deployed a new Kubernetes cluster with Karbon and downloaded the kubeconfig, kubectl operations result in an error:Unable to connect to the server: x509: certificate is valid for cluster.local, kubernetes, kubernetes.default, kubernetes.default.svc, kubernetes.default.svc.cluster, kubernetes.default.svc.cluster.local, cluster.local, not xxxxx What is the recommended way to add a SAN to the Karbon Kubernetes API certificate?

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. I noticed that the volumes are created normally

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.

Using NAT Destination on Virtual IP of Cluster for Remote Sites

Hi, I just deployed my 2 clusters on separated Data Center. Right now i have no Link between them besides Internet (No VPN). Can i use NAT Destination of IP Public of each Data Center for the target of Remote Sites Configuration?Example:Data Center A : 123.234.123.234:2020 > NAT Destination to > 250.250.123.123:2020Data Center B : 234.123.234.123:2020 > NAT Destination to > 200.200.123.123:2020Can we configure like that in order to Remote Sites Configuration to work?

CVM fails to boot due to disk errors

I have a problem with a CVM that won’t boot. This is on a semi-retired production cluster (not CE) that has no workloads running on it.I found the console output in /tmp/NTNX.serial.out.0 and I can see it trying to enable RAID devices, scan for a uuid marker and find 2 of them, then abort and unload the mpt3sas kernel module before trying again in 5 seconds.

Nutanix Data Protection to the Power of Public Cloud

Since its inception; the Nutanix platform has offered customers a robust set of data protection technologies.  Many of our customers leverage these capabilities as a part of their DR strategy.Now, with the advent of Nutanix Clusters (on AWS bare metal today) extending the capabilities enabled by the data protection suite to the public cloud is now a reality.  Nutanix Clusters on AWS deploys the Nutanix HCI stack onto AWS bare metal instances.  Provisioned via a customer portal customers can have a public cloud resident Nutanix Cluster operational in very short order.At which point they’re ready to leverage the public cloud as a part of their DR strategy; while maintaining a familiar operator experience:

Elastic DR with AWS (X-play and Clusters Portal API)

I make no bones about it, bare-metal nodes in AWS is pricey. The questions becomes if we want to save money and have DR with AWS, how do keep the number of nodes small until we failover?In AWS all the Nutanix rules still apply. We need a minimum of a three-node cluster to get started. If we have enough storage capacity, we can keep accepting replications from an on-prem cluster and not worry about CPU and memory constraints. You could also use your on-prem AHV supported backup software to backup directly to S3. Then when you have an outage, you could quickly build a Nutanix Cluster in AWS and start restoring the data to that cluster.DR on the skinnyI was a asked to automate the process of adding nodes to a small Nutanix Cluster in AWS and then start a failover using Leap (DR runbooks) and X-play(automates actions based of events and alerts) in Prism Central (PC).  The below video is what I came up with.  The code to add a node via API from the Cluster portal is listed here:https://gith

Airgap for K8s external components

Is it possible to use Airgap to store additional K8s components like Flux, Ingress controller etc.? I’m using terraform to deploy Karbon, so I should be able to access airgap registry from those deployment modules. How do I manage airgap registry, is it standard private container registry? How about helm charts, can airgap registry store them also?

P2V SQL servers to Nutanix

Hi Folks,I want to virtualise 2 SQL servers on Cisco UCS hardware to Nutanix. I found references for Xtract for DB, however it seems it is a legacy tool as I am not able to get much information on it. Nutanix ‘Move’ seems to be used for VM migration.On Nutanix I have ESXi, so i know we can use ‘Vmware Converter’, but I would like to know if there is any solution from Nutanix for this.Can some one please guide me about the ways I can achieve this P2V of SQL servers?

Karbon, Rancher and similars

Hello friends,From what I have read in the Karbon documentation, as well as from YouTube videos, through karbon in AHV I cannot manage aspects of the containers, the applications themselves, load balancing, reverse proxy, container images, etc. Is that right?Associated with this, if Karbon does not in fact have such features, is it possible to use Karbon in conjunction with tools that have the above features, like Rancher? Has anyone had this experience?

Data service IP vs direct attach when connecting Volumes

When I searched the documentation, it was said that scsi-3 pr3 is supported when attaching volume from AOS 5.17.my curiosity1. In versions prior to 5.17, when allocating a shared volume for vm redundancy configuration, if you use Attach instead of using iscsi-initiator, does it not work?2. Considering I/O speed and stability, which do you think is better, mounting a volume through iscsi-initiator or connecting to a VM as a direct attach?
