Nutanix Cloud Clusters (NC2)

AOS 6.7 has added more options for securing your cluster in AWS. We will take a look at the existing options and dive into the new feaure in AOS 6.7.You can use AWS security groups and network access control lists to secure your cluster relative to other AWS or on-premises resources. Nutanix automatically creates three security groups to limit traffic to the cluster:Internal management: Allows all internal traffic between all CVMs and all AHV hosts (EC2 bare-metal hosts). Don’t edit this group without approval from Nutanix Support. User management: Allows users to access Prism Element and some other services running on the CVM. UVM: Allows UVMs to talk to each other. By default, all UVMs on all subnets can talk to each other, but you can edit the policy to lock down more traffic. You could alternatively use

We are experiencing issues with the "ncc health_checks run_all" command on the Nutanix CVM machine, both from Putty and the web console. The checks are failing or aborting after waiting for more than 30 minutes. Your assistance in resolving this matter would be greatly appreciated. Thank you.

Hybrid Cloud extended network between Azure and private datacenterThis is just one possible scenario that you could use create a Layer 2 stretch network in your hybrid cloud environment. The goal is to understand this scenario and to have a place to ask questions. The plan is to introduce additional scenarios to drive understanding. This scenario is using AOS 6.6. The scenario will mostly likely change with newer AOS releases. We have an Azure environment on the top the below diagram and private datacenter below the Azure environment.  We want to understand what happens if the VMs running on Nutanix in Azure failback/migration to the private datacenter while using layer 2 stretch. After the failover, how will the native Azure VMs in Step 4 reach the VMs that failed/migrated. The VMs running the NC

Ever wondered how to setup a Nutanix cluster on OVHcloud? Here is a blogpost that would probably tick all boxes with questions: https://www.jeroentielen.nl/running-nutanix-on-ovhcloud/  

Hi! I would like to find out whether there is any timeline to support vSphere 8.0 for NX G8 nodes?

Hi,New to Nutanix. Setting up our new Nutanix cluster that will run VMware as the hypervisor. Is it recommended to create 1 storage container that utilizes all storage capacity for all VMs (150) to reside? I am use to creating multiple datastores in a traditional 3 tier architecture, but i know a lot of those practices go away with hyperconverged.The main reason I ask is that although we have no plans at this point to use other Nutanix services such as Files or Database, I don’t want to be in a position if I create a storage container for VMware VM’s and assign it all of the capacity and then find out later that I cannot use Nutanix Files because all space was initially given to VMware.Any recommendations or best practices you can share to ensure I don’t shoot myself in the foot?Thanks

When you don't control the networking stack end to end or you're in an environment that simply doesn't have a firewall you can use Nutanix Native DR encryption between your Nutanix clusters.  The feature is fully supported for both PD and Nutanix DR(PC) based replication.Changes will persistent after reboots of the CVMs and upon upgrades.AOS needs to be on 6.1 or higher.DR with Encryption will use 14119,14108 as additional ports that need to open bi-directional when all of the CVMS. *** Note you need to run the below steps on each cluster.To enable this featureSSH to the CVM Cha

Hello All, I'm working with a customer on a new solution designthe customer has a VMware workload and we plan to put AHV,I want you to advise me on how I calculate the storage requirement, Let’s say the customer workload is about 170 TB how do i size the cluster storage Also, I have some questions related to storage sizesif I have 3 nodes clustereach node with 10 disks each disk 4 TB (numbers for examples only)that means total raw storage is 120 TBwe will go with RF2 which means 1 node is out of our usable capacity calculation So what is the usable capacity here after the 1 node for failure and the Raid used in the cluster creation, also what else should be conducted from the storage in storage planning?

The Flow Gateway VM (FGW) for Nutanix Cloud Clusters In Azure(NC2) is the Lynch pin to having a your own Supercloud. The FGW is responsible for all VM traffic going north and south from the Nutanix cluster in Azure. This virtual machine allows outside communication from both cloud and on-premises services to the workloads running on the Azure NC2 Cluster.   The Flow Gateway VM connecting Azure and on-prem services to the Nutanix Cluster deployed in Azure.Once Prism Central is automatically deployed from the cluster creation process, the FGW deploys into the same VNET that Prism Central is using.  The FGW is a native Azure VM. The VM has two network inter

One of the biggest changes with Nutanix Cloud Clusters (NC2) on Azure compared to it's AWS counterpart is the requirement for Flow virtual networking. Flow virtual networking provides an overlay in Azure to provide secure communication between multiple tenants you may be hosting on the Nutanix cluster and also provides north and southbound connectivity. North and southbound connectivity is provided through the Flow gateway virtual machine (FVGW). Workloads running on the cluster can either go through a network address translation (NAT) path or a routed path not using a NAT. Which path your virtual machines take in and out of the NC2 Cluster will depend on how other services need to talk to the running virtual machines on NC2.The FVGW Is a native Azure VM that gets deployed when the first cluster is created. The FVGM has both and internal and external network interface c

Hello All,        I have added a managed network in our cluster. We have since purchased another cluster and in the process of configuring VXLan and the ability to live migrate VM’s between clusters. From what I have been seeing we cannot have a managed network across clusters is this correct? If not does anyone know how to configure a managed network to work between clusters.Thanks,Scott

Dear All,Please, is there any changes in the exam questions of NCP-MCI 5.15 and NCP-MCI 5.20. Because i have done the training for NCP-MCI 5.20 and i would like to take the exam by next month.

I would like to use cluster api to deploy my K8s cluster in an hybrid manner. Vsphere and AWS are CAPI provider. Will Nutanix support that?

I would like to take full blame for people thinking self healing solves all problems with Nutanix Cloud Clusters (NC2).  The self-healing is pretty awesome for bad nics, hard drives and nodes but there are some instances where the portal can’t take action.Status checks on AWS are performed every minute, returning a pass or a fail status in the Cloud Portal. If all checks pass, the overall status of the instance is OK. If one or more checks fail, the overall status is impaired.There are two types of status checks, system status checks, and instance status checks. System status checks monitor the AWS systems on which instance runs. Instance status checks monitor the software and network configuration of individual instances.  Notification Center in the Clusters P

Hi Team,Does anyone know when AOS 6 LTS version will available? On Prism or support portal.

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 al

 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.

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……..
