Running Red Hat Openshift on Nutanix AHV

The technical piece below found our way through our partner channels. Installation instructions for Red Hat OpenShift on Nutanix are detailed in the documentation below. Enjoy, and as always feel free to provide us with feedback. User Provisioned Installation of Red Hat OpenShift 4.3 on Nutanix AHV 5.15 This manual was created during a proof of concept environment using Nutanix AHV 5.15, the KVM-based hypervisor of Nutanix, with OpenShift 4.3 in combination with the Nutanix CSI driver. The Nutanix CSI driver provides scalable, persistent storage for stateful applications using Nutanix Files and Nutanix Volumes. Please note: At the time of writing, Nutanix AHV in combination with OpenShift is supported by Nutanix, but not certified by Red Hat. If certification is required, clients are advised to use any of the other hypervisors supported by Nutanix. The installation steps followed are documented in the IBM Cloud Architecture & Solution Engineering repository guide. The PoC envi

Defragment Guest OS

I was wondering what best practice is for defragmenting guest OS on a Nutanix node.  I am running ESXi on the nodes.  I have looked all over but I cannot find anything that tells me definitively the best practice.

Veeam Backup Chain Break after Nutanix VM failover and back

I’m new to Nutanix and we are using Prism Pro to move a VM from one 6.7 Vmware farm to another and back again. That works 100% but Veeam V11 can not see the VM once it is moved. It’s like the UUID is wrong but I have checked that and it is ok (same) Support are looking into this and are saying this is a unique case… surely this must be common? If there is no solution we will end up with the same VM added to the Veeam backup job, again and again… I have tried using TAGS and direct add to veeam…

Async Protection Domain

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.

Commvault with Nutanix - Best Practices Checklist

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. With ESXi, use NBD as the transport mode whenever possible. With ESXi, configure the management network interfaces t

Self Service VM Customization

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.

Nutanix CVM - diskspd

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.

Integrating 3rd party backup with Nutanix

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 Alliances Partners within Backup & Disaster Recovery. This is a high level overview of the process. It consists of following components Backup Server Configuration database (usually deployed within the backup server or within the appliance (depends on the vendor)) Proxy (deployed within the NTNX cluster) Repository NTNX Cluster Following Services are involved in creating 3rd party snapshot  Apache Web Service - handles all API calls to and from the backup software Prism - tracks all API v1 and API v2 calls Aplos and Aplos Engine - tracks API v3 calls aplos_engine is responsible for the aplos snapshot (Snap UUID - kind UUID) creation Ergon -

Determining appropriate methodology for cpu over subscription

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.

Easy way to put Vmware ESXi host into maintenance mode.

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.

Windows 2019 Standard edition guest OS licensing on AHV

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.

Data protection Migration and failback

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?

Any HYCU Users Here?

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!

Nutanix replication or recovery with volume group

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.

Nutanix Disaster Recovery Solutions

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 specify in the RPO) and replicates it to the recovery site NearSync replication: It enables you to protect your data with an RPO of as low as 1 minute.The policy creates a recovery point of the VMs in minutes (1–15 minutes) and replicates it to the recovery site. You can configure disaster recovery with NearSync replication between two AHV or ESXi clusters at the same or different on-prem sites Synchronous replication: It enables you to protect your data with a zero recovery point objective (0 RPO).You can configure a protection policy with Synchronous replication by defining the VMs or VM categories that replicate all the writes on the pro
