Authorization Configuration using full resources of DC VM

Authorization configuration is enabled in two clusters and directed to same Domain controller, which is a VM in one those clusters After that when I use prism API to get stats information of various VMs (I invoked it repeatedly for each VM) it is resulting in 100 % CPU usage in Domain Controller to confirm the same I changed the DC to another VM then the first DC device CPU usage got reduced and second DC device CPU usage raised to 100% API used : /PrismGateway/services/rest/v1/vms/<uuid>

Upgrade firmware on HPE DX by using Darksite LCM

Hi, I have built up a Darksite LCM running in my own local network and have Internet access to download necessary Darksite bundles for upgrading. In my testing evironment, the server works flawlessly with Dell XC cluster and Nutanix cluster as well but with DX cluster, it cannot provide any firmware update at this time though currently at least 1 node in our cluster is running on an old SPP version (2019.03.01). For our DX environment: Node1: 2020.03.0 SPP Node2: unverified? (LCM cannot detect the SPP version) Node3: 2019.03.01 SPP Does anyone have any idea on this case?

Certificate Revocation Checking

There are two ways of  checking certificate revocation in client authentication: Using OSCP (nCLI) Using CRL- Certificate revocation lists (nCLI)   OCSP is the recommended method for checking certificate revocation in client authentication. You can enable certificate revocation checking using the OSCP method through the command line interface (nCLI).   What is OCSP ? The Online Certificate Status Protocol is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate.   How does OCSP Work?  When a user requests the validity of a certificate, an OCSP request is sent to an OCSP Responder. This checks the specific certificate with a trusted certificate authority and an OCSP response is sent back with a response of either 'good', 'revoked' or 'unknown'   To enable certificate revocation checking using OCSP for client authentication, do the following. Procedure Set the OCSP responder URL. ncli authconfig set-certificate-revocati

Life Cycle Management (LCM 2.3.2)

It enables administrators to take inventory of the firmware and software in their Nutanix environment and perform updates in a simple, cluster-aware, fashion. LCM adds a management layer and logic that deploys firmware/software upgrades taking into account upgrade paths and potential conflicts between versions.  LCM performs two operations: Inventory: Detects what can be managed on a cluster. Update: Performs an update to a certain version. With Release of LCM 2.3.2 we have introduced a new page which shows best practices guide and redirect you to FAQ’s troubleshoot guide     it introduces two new FEAT’s along with several others AOS upgrade FEAT-10222 PC upgrade FEAT-10223 List of supported Firmware updates Nutanix (NX) Dell XC / XC Core Lenovo HX / HX Ready HPE DX Fujitsu XF Intel DCB HPE DL (G10) Inspur InMerge Please follow the links to check out additional information https://portal.nutanix.com/page/documents/details?tar

Configuring VMware Distributed Switch (vDS) on the Nutanix Platform

Nutanix cluster works with the vDS and you can use the following guidelines and recommendations to configure the vmk and VM interfaces to be part of the vDS. Nutanix recommendations for implementation Keep the vSwitchNutanix, the vmkernel port (vmk-iscsi-pg), and the Nutanix Controller VM's virtual machine port group (svm-iscsi-pg) configuration intact. It should remain as a standard vSwitch and should not be migrated over to the vDS. Migrating the vSwitchNutanix to the vDS causes issues with upgrade, and also controller VM data path communication. Only migrate one host to a dvSwitch at a time. After migrating the host to the dvSwitch, confirm that the Controller VM can communicate with all other Controller VMs in the cluster. This ensures that the cluster services running on all Controller VMs continue to function during the migration. In general, one Controller VM can be off the network at a given time while the others continue to provide access to the datastore.

CPU sizing - Applied weight

Hello, guys Please, help me with these two points: I’m searching for the spec int value that the sizer uses. For example, I see that a default processor is E5 2680v2, 42.31 specInt. But I searched on the website of Spec.org and I couldn’t find that and the other serverals values that use Nutanix sizer, as is shown in the picture. Maybe I search on the incorrect section of Spec.org, 2006? 2017? Please help.   I was wondering if the applied weight value is published in any website of Intel. I figured out that it is a fix value: 7.3 per processor for Xeon Gold 6244, for example. I wrote down the applied weights for 3,4,5 and 6-node configuration (dual-processor) and the calculations works this way: Applied wieight in 3-node cluster: 43.8 (7.3x6) Applied wieight in 4-node cluster: 54.8(7.3x8) Applied wieight in 5-node cluster: 72.99(7.3x10) Applied wieight in 6-node cluster: 87.59(7.3x12)   So I would like to know if these values (7.3 and others) are associated to the processor its

vSphere cluster settings for Nutanix cluster

The Nutanix cluster in Vcenter must be configured according to Nutanix best practices.    A quick checklist for the recommended settings review is as follows:   vSphere HA Settings   Enable host monitoring   Enable admission control and use the percentage-based policy with a value based on the number of nodes in the cluster.   Set the VM Restart Priority of all Controller VMs to Disabled.   Set the Host Isolation Response of the cluster to Power Off.   Set the Host Isolation Response of all Controller VMs to Disabled.   Set the VM Monitoring for all Controller VMs to Disabled.   Enable Datastore Heartbeating by clicking Select only from my preferred datastores and choosing the Nutanix NFS datastore. If the cluster has only one datastore, add an advanced option named das.ignoreInsufficientHbDatastore with Value of true.   vSphere DRS Settings   Set the Automation Level on all Controller VMs to Disabled.   Leave power management disabled

Disk structure of a CVM

Disk structure of a CVMThe CVM is the core of the AOS clusters, but have ever wondered how disk layout exists within them?I provide a brief overview of its structure in the following post.The main thing that most of you are familiar with already, is that the LSI controller is passed directly to the CVM in order for it to have direct access to the disks in the node. When combining all the disks space from all the CVMs within the cluster it provides the unified software define storage pool used to store your data.That’s why when you run “df -h” in the CVMs you will see the data disks mounted in the following mount point:/home/nutanix/data/stargate-storage/disks/<disk serial_number>However, the CVM also needs to have space for itself in order work, so a portion of SSDs and HHD is reserved for that purpose.In single SSDs system you will get the following partition layout:   sda1: ‘/ ‘ root partition sda2: standby root partition used for upgrades  sda3: /home partition

Quick Start Guide to AOS Upgrade

Acropolis Operating System upgrades happen across the cluster, one CVM at a time. Here is the next installation of the Upgrade Series as promised to provide you quick tips and tricks to plan and execute your upgrade activities with ease.   In simple words, AOS is the Operating System running on the Controller VMs(CVM) in the cluster and is critical in handling the data I/O from the user VMs in the cluster. AOS can be called the core of Nutanix Hyper-converged infrastructure.   As reference documents, you can check the below Guides: AOS Advanced Administration Guide Prism Web Console Guide Acropolis Upgrade Guide 2 Node Cluster Upgrade Reference Guide Note: The above listed documents are for the latest LTS release - 5.15.x (as of 17th July,2020).

Migrate VM's out of AHV

You must be familiar with some of the techniques you can use to migrate VM’s onto AHV from other hypervisors. These include our popular Move solution, if you wished to move away from ESXi or Hyper-V. Another way is to add the VM’s into a Protection Domain and migrate the PD itself. Of course, this is only compatible with Nutanix clusters being the source and destination cluster.   As much as we would not want you to, there could arise situations where you may need to transfer VM(s) back to a different hypervisor. Currently, Move does not apply to this use-case. The quickest way would be to set up a Protection Domain as described above. However, this is complicated if the VM’s are already being protected and replicated onto other clusters. You would not wish to remove them and affect the processes in place.   What do you do then?   This document should assist you in the process. On a high level, it includes  Powering off the VM Using the qemu utility to convert the vdisk

Cable managers for Nutanix hardware

Dear Sir/ Madam, I am working on a further Nutanix project and I have installed 8 x NX8155 servers. Each server has 6 x 10g TwinX cables and 2 x CAT6 copper connections. I am again trying to find any suitable cable manager due to the amount of physical cabling for each device. Can someone please advise if there are any cable managers that Nutanix is aware of or via a third party as I am struggling to locate any. Thanks in advance. Simon.

Nutanix Cluster Upgrade and What It means to you.

We often ask ourselves, what do these various Upgrades entail and what actually happens during an upgrade. Here is a high-level description of what happens during the various Nutanix core software upgrade processes. I have assumed it is a minimum 3-node cluster and you have already determined the Upgrade version.  Note for all the Upgrade below, it is important to perform health checks before upgrading any component (check KB 2852).   1. NCC: When : If health checks show no issues,  the NCC upgrade can proceed. It is recommended to upgrade to the latest NCC version shown.  How : The upgrade process copies NCC software to each Controller VM or Prism Central VM. What Happens : The cluster_health service, which is responsible for health monitoring and the logic underlying cluster alerts, restarts on each node.  Caution Level :  No services involved in the data path restart hence it is non-intrusive.  NCC version does not depend on any other Nutanix component and can be upgraded re

AHV networking

AHV uses Open vSwitch (OVS) to connect the CVM, the hypervisor, and guest VMs to each other and to the physical network.    Open vSwitch: OVS is an open source software switch implemented in the Linux kernel and designed to work in a multiserver virtualization environment. By default, OVS behaves like a layer-2 learning switch that maintains a MAC address table.  Bridges Bridges act as virtual switches to manage network traffic between physical and virtual network interfaces. The default AHV configuration includes an OVS bridge called br0 and a native Linux bridge called virbr0 Ports Ports are logical constructs created in a bridge that represent connectivity to the virtual switch BondsBonded ports aggregate the physical interfaces on the AHV host. By default, a bond named br0-up is created in bridge br0   VLANs for AHV Hosts and CVMs     The recommended VLAN configuration is to place the CVM and AHV in the default “untagged” (or native) VLAN, as shown belo
