Nutanix Cloud Infrastructure

Hi All, I'm wondering what configurations people have on Async Protection Domains? How many VMs per PD Create many PDs and group by application/department/roles eg[list] All Web servers in one group, all SQL servers, all application servers All HR based systems, All IT based systems, All Fiance based systems Is there a limit on how many PDs you can have in a cluster What's the dis/advantage to having fewer large PDs over many smaller PDs What frequency and retention are the local/remote snapshots What issues arrise when activating a PD I believe the IP address will be removed and the MAC will change...correct??, any scripts or automation applied?[/list] Thanks for any response you can give. Regards Dave

Use a Nutanix cluster external Data Services IP address when using IntelliSnap. Install a VSA on every Nutanix compute node. Install the MediaAgent software on all the VSA proxies. Install CommServe and MediaAgent on a secondary Nutanix cluster to separate backup and production infrastructure to protect against failure. Follow Commvault sizing guidelines. Create a virtual server client proxy group for easier management. When using IntelliSnap, colocate the MediaAgent software with the VSA. With ESXi, when you add ESX hosts to vCenter, make sure that the format of the ESX host name matches the host name format in vCenter. For example: If the host name format is short name, use short name to add the host to vCenter. If the host name format is FQDN, use FQDN to add the host to vCenter. If the host name is an IP address, use the same IP address to add the host to vCenter.

I want to introduce Self-Service VM operations via Prism Central for our end-users (do not have CALM). So, I’ve used cloud-init (Linux VMs) and cloudbase-init (Windows VMs) along with customization code (Python) to deliver this Self-Service VM provisioning experience. You may refer https://github.com/cybergavin/nutanix/tree/master/self-service for details of this set up. Any feedback always welcome. Sorry if the code isn’t too pythonic as I’m a python newbie.

I’m new to Nutanix and we have a Nutanix cluster online. For testing purposes I’m running diskspd test in a VM.I’m running some diskspd test with identical VM configs in several enviroments 3-tier Hyper-V/ VMware and HCI Nutanix AHV.Why is it that running a test with -Sh flag (no software/hardware cache) gives almost 10 times lower results in Nutanix compared to other platforms? Without -Sh flag Nutanix is running test with higher results compared to my other testing platforms. Is it because of how CVM is designed to work? I’m just trying to understand.

Third party backup integration is data protection that involves creating snapshot and backup copies via third party backup software. The requirements for integration changed depending on the backup software being used. Some of the supported backup vendors are HYCU Veeam Commvault Cohesity Rubrik For full list please visit

We are new to Nutanix. We are migrating from ESXi to AHV.  We currently have some level of CPU oversubscription in place on ESXi.  We anticipate the need to oversubscribe CPU on some clusters and I am looking for ways to do this safely.  I’ve looked in the Best practices guide but there was very little there.  Any help would be appreciated.

I want to try FRAME with azure to see what it give “hope” azure native login is supported.I created the enterprise application  , the secret etc..  the only step that i change is that i set the owner permission on the RG quite better than the subscription but i receive an ADAL error during  authentication ;  this is maybe because ADAL is depreciated ..  could you warn the support about it  ?

Hi,We have PRISM Central Pro license and I’d like a report or Analysis view on which virtual machines are consuming the most memory. The Cluster in question is VMware 6.7. Is this possible and what is the best way to go about it?

Good afternoon, all!I’m setting up a new PKI infrastructure in a Nutanix cluster and I want to shut down the root CA for safekeeping. Is there a way to add some safeguards so that the VM can’t be started inadvertently?

I know there’s another topic like this but, it is 3 years old. Is there an easy way to put a single ESX host into maintenance mode?Not to compare products but with Cisco Hyperflex, you right-click on the host and there’s a “Hyperflex maintenance mode” option.  This does what needs to be done to the CV without having to SSH into anything.I was just wondering if the process has improved in 3 years.

Hi,I cannot expand the cluster when Pre expand-cluster tests were failed and error message was "Failure in pre expand-clustrer tests.Errors:Failed to get vlan tag of node:XXXXX" on Prism Element.CVM and HyperVisor Network use Tagged VLAN and PortChannel in L2 switch ports.Ping to HyperVisor’sManagement IP from other NW segment is OK.Of course, CVM and HyperVisor’sManagement IP are same segment.Should  I do any other? As below, each of versions.・DELL XC640・AOS：5.10.6・ESXi：6.7 Update 2 (Build 13006603)

Hi, We have deployed couple of guest VMs on Windows 2019 Standard Edition OS on our 6 node cluster. Both the guests are configured with 1 VCPU with 2 cores along with 16 & 32 memory respectively. We have procured standard paper license of the OS. The hypervisors are running on AHV version 20170830.337 & AOS - 5.10.8.1 LTS. Is there any specific licensing model for Windows Server OS to run on AHV? How are the Windows licenses determined? Kindly help.

Hi, I’m new on the Data protection feature. I’ve done the a test VM migration to another nutanix cluster. The thing is after the migration, the VM on the source will be destroyed. I’m planning to use the Data protection to migrate the VM from the source cluster to the target cluster. I would need to failback the VM to the source VM. Am I able to restore the VM on the source site? 

Hi All,Does anyone know that veeam can directly add prism central(AHV) for backup?

We are currently evaluating Nutanix and also HYCU for backup. So far HYCU looks really good running on my CE lab server but there is one issue that they cannot answer to. For file restores on older recovery points (past the "Fast Restore" point), HYCU must copy the entire VM from the storage target and mount it to even start the search for a file. While for small VM's this my not be a big deal, larger VM's would cause a wait time based on your network connection to the storage target. For anyone using HYCU is this a concern to you? I'm very interested in hearing real world feed back here. Thanks!

Hi Everyone,I want to know what nutanix version can do replication or leap recovery plan with volume group (iscsi)? I currently use the CE version for testing ,my Nutanix CE and PC version are NUTANIX 20190916.276.I'm testing the iSCSI space of volume group mounted on Windows Server,then execute the plan of leap failure. However, after my windows server fails to DR, there is no iSCSI space on the windows server, and I do not see that the volume group is sync to DR.Is there a problem with my configuration, or is the CE version not supported at present?Has anyone ever done this test?Thanks.

Hi! have a Project in Prism Central that's acting wierd.When i try to update the Project trough GUI i get this error message:Edit conflict: please retry change.Notification { "api_version": "3.1", "code": 409, "kind": "project_internal", "message_list": [ { "message": "Edit conflict: please retry change.", "reason": "CONCURRENT_REQUESTS_NOT_ALLOWED" } ], "state": "ERROR" }So i connect with SSH to a PC CVM, and try to delete the project trough nuclei,<nuclei> project.delete Project \Name confirm=trueConfirm deletion of project? (yes/no) yes{ "message":{ "kind": "project","code": 409,"message_list":[ { "message": "Edit conflict: please retry change.", "reason": "CONCURRENT_REQUESTS_NOT_ALLOWED" } ],"state": "ERROR", "api_version": "3.1" } }It is only the specific project that has this problem, other projects works just fine.

Nutanix offers a variety of DR solutions. The flowchart provides a detailed representation of disaster recovery solutions.  Leap with two Prism Centrals: Asynchronous replication: it enables you to protect your data with an RPO of 1 hour or beyond.The policy creates a recovery point of the VMs in every 1 hour (or in the hourly time interval that you sp

Why a Grizzly bear? Why not? Awhile ago I created a video showing how you could easily save lots of money by saving dollars on the EC2 costs by using hibernate. Nutanix Clusters is the only on-prem vendor offering this  for customers that want to lift and shift to the public cloud or use the public cloud for DR. I want to share the code snippet and how to create an API user in the Clusters portal.You can first get familiar with hibernate here:  To create an API user to make the call:Go to the Clusters portal  Under Organization go to users

Hi , Could you advice me  ?Now, Hypervisor and CVM is NOT syncronized from NTP Server.I use CloudConnect everyday , but that was failed.Is CloudConnect faiure reason relevent to NTP Server unsyncronization? TestConnect is OK from Onpresmiss Cluster to AWS.I read this;https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v5_17:wc-cloud-connect-wc-c.htmlSincerely, 

Just curious how other users running AHV plan their ad disaster recovery?  AHV does not support VM-Generation ID so it looks like the most straight forward method not including additional software would be to use the builtin server backup to backup and restore at least the server with the fsmo role.  I wonder what happens in a protection domain scenario especially if there are multiple servers.  Seems like there could be usn rollbacks issues.  Any input on how others are doing it would be appreciated since the documentation seems to be scarce for AHV.

Hi, I am always taken care. I use CloudConnect by VPN connection to AWS and enable NW compression.Everyday repeat that.Since 1 year ago, All PDs are failed. below the message on Prism ;---Replication was skipped for protection domain XXXX of snapshot (X,X,X) to remote site XXX. Replication was skipped as a newer snapshot was available.---I executed cli on CVM, replication statuses are “Sending” .---$ncli pd list-replication-status Replication Operation     : Sending And I did “Test Connection” on Prism was “OK”. What do you think this reason? Sincerely,

Hi,I am always taken care.I'll upgrade Hyper-V 2012R2 to 2016 on XC630 so I have some questions.・metadata(json) download from Nutanix Portal. Can I do that Hypervisor ISO file there ?・What difference are metadata(json)  each ? ・Use Hypervisor ISO file of Evaluation version, is it OK?・ISO's language adapt any languages? or English only? Sincerely,

Hi,I use vSphere6.0 U3 on NX series and set AsyncDR replication to AWS.Some protection domain’s AsyncDR are errorred after VCSA has broken and re-deploy.Are AsyncDR and vCenter  depend on each ?Sincerely,
