How It works

I compile my code, now the user should not install anything .. just run and choose graphically where you want to record the report and the information looks much more orderly and complete. It is an extensive summary. 1) You just need to unzip the .zip and run the executable named NUTANIX_TOOLS_FOR_AHV_v1.7.9_PORTABLE.exe 2) A window opens where you must select where to save the report.

Let’s say that you want to dive deeper into the performance of your AHV cluster to understand if the resource allocation has been done correctly and to check how many CPUs, Cores per CPU and Threads reside on each host. To see the CPU components, SSH to a CVM in your cluster and run ”hostssh lscpu”:   The result above is an output example of one node, for this host there are: Sockets = 2 Cores per socket = 6 (2x6 = 12 in total) Threads per core = 2 (2x12 = 24 in total) CPUs = 24 (threads in total) If you wish to see more information for each of the 24 CPUs on this host you can run "cat /proc/cpuinfo" on a host shell (not through the CVM). To jump from the CVM to it’s host, run “ssh root@192.168.5.1” and run the command

Regardless of the type of data you generate on your VMs, the data has to be backed up and safe. how do you make sure of that? a first step is to understand our basic approaches and how do we guarantee data resiliency.  The importance of data protection increases as the amount of data generated by your VMs continues to grow at unprecedented rates by expanding your storage pool, adding nodes to your cluster and deploying new Virtual Machines. To ensure that the data is safe, we have different approaches, here is a brief explanation for each:  Protection Domain (two types) Protection domain - Asynchronous DR: is a defined group of entities that consists of VMs and Volume groups that are backed up locally on the cluster and can also be replicated on a remote site.  Protection domain - Metro Availability: is a pre-specified and an active storage container in the local cluster linked to an inactive container with the

Let’s say that you need to use Phoenix on a node, how do you know which ISO is best for you? the minimal or a bundle of Phoenix & AOS? How do you create the bundle?   The short answer for both questions is, it depends. What is Phoenix? Phoenix is an ISO-based installer that you can use to perform installation tasks on bare-metal hardware one node at a time. Tasks that performed by Phoenix:  Configuring Hypervisor settings, virtual switches and more (no need for AOS in this case) Installing the Controller VM which runs the AOS. Installing the Hypervisor on a new or replacement node.  Repairing the CVM.  If you don’t have access to the CVM and you want to check the data drives’ health, you will be able to see the drives from the Phoenix shell. How do you obtain the correct Phoenix?  Looking at the scenarios above, we can see that

We are thinking of adding two compute only nodes to our cluster for Oracle.  What are the hardware requirements for running CO nodes?  Does the cluster the CO’s are joined to have to be all flash or do you have to “pin” the VM’s running on the CO to All Flash in the HC storage.   We currently have 4 HC nodes running a mix of SSD and HDD. 

Hi, I am having a Hyper-V cluster managed by a SCVMM with Kerberos enabled. I already did: Join the cluster and hosts to domain Create the MSFC and join to domain Add hosts and Nutanix container share to SCVMM Enable Kerberos and configure Delegation But, from each host, I currently cannot: Access to Nutanix container via SMB path (\\VIP\container). When I type the SMB path into file explorer, it requires me to login. I tried to use the AD account used to enable Kerberos on Prism as well as AD admin account but could not make it Create the VM (I could create the VM by using SCVMM instead). “Failed to create the virtual hard disk” error window appears every time  I try to create Is this the normal behavior of the whole system? As I am quite new to Hyper-V, I am getting lost in finding the solution to solve it

Confused regarding crash-consistent snapshot and application-consistent snapshot? Crash-Consistent SnapshotVM snapshots are by default crash-consistent, which means that the vDisks captured are consistent with a single point in time. The snapshot represents the on-disk data as if the VM crashed or the power cord was pulled from the server—it doesn’t include anything that was in memory when the snapshot was taken. Today, most applications can recover well from crash-consistent snapshots. Application-Consistent SnapshotApplication-consistent snapshots capture the same data as crash-consistent snapshots, with the addition of all data in memory and all transactions in process. Because of their extra content, application-consistent snapshots are the most involved and take the longest to perform.While most organizations find crash-consistent snapshots

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.

The cluster is up and running and we are getting error “Disk 'root' space usage high on host” Can /home/install/phx_iso be deleted?

Hello all,   Hope you’re all doing great. Kindly if you can guide me where to start with Nutanix as I don’t know anything and willing to know everything related .. so I am a VMware guy who is willing to understand the NU platform and I hope I am writing the right post in the right place      Thanks in Advance, Cheers.

 In some scenarios, we might have a need to find the disks associated with a virtual machine hosted on a Nutanix AHV Cluster. Nutanix offers a distributed storage fabric, which forms a large storage pool across “N” number of nodes. we then create containers for different types of workloads or we can easily use a single container as well.Virtual Machines are created via Prism Management and all vDisks associated with the VMs are hosted on the distributed storage pool. On a Nutanix AOS Cluster, Acropolis service runs across the cluster to manage virtual machine operations and configurations. As both Data & MetaData is distributed across the cluster, we can use the “Acropolis” service on almost any CVM to retrieve virtual machine information running on any node.In order to interact with the Acropolis service, Nutanix offers “acli”. a powerful set of commands for virtual machine op

Nutanix AOS supports multiple hypervisors and supports a variety of hardware components. Nutanix qualifies hardware components to ensure optimal performance and minimal disruption.  Nutanix AOS with ESXi supports Intel’s 10Gb (ixgbe) Ethernet Network Adapters. It is important to ensure that all network related components are working optimally to ensure reliable cluster operations.  If you are running Nutanix AOS with ESXi 5.5 or 6.x and have the following Intel Network Cards installed in your host systems: Intel Ethernet Controllers 82599 and x540 You might receive an NCC alert, pointing to an upgrade required for ixgbe nics or an older firmware detected. This is to ensure optimal networking performance amongst the hosts and to avoid any errors due to NIC driver issues. You can upgrade the firmware for the above Intel NICs (ixgbe) with the following Nutanix KB:

  I have AHV cluster at both DC & DR, which has number of VMs being protected with Protection Domain feature. These VMs are being replicated from DC to DR in scheduled manner. Now as a part of DR drill, I need to run these production VMs from DR for period of time and then again make it functional from DC once drill is over. I am concerned over how the delta changes made during drill with VMs at DR will be again replicated back to DC as Protection Domain replication is uni directional (DC to DR) ? Any recommendations ?
