Hello Nutanix CommunityI have a VM that is running CCTV operations. I record multiple video streams in a high resolution and frame rate. Old files get deleted when the space is used up. How can I make sure that the SSDs are not being used for the recording to avoid them to get too many write cycles too fast?Kind regards,Ibinema

Hi All,Just after some advice.  I’ve run the default ‘Four Corners Microbenchmark’ against 2 x identical All Flash clusters and I get very different results and not sure why.The average random read IOPS differ by around 60k, and the random write IOPS around 10k. I know running the test on both clusters will not provide an exact match, but these results appear very different.  Please note these are both 2-node clusters, both are identical in specification so not sure if this matters.I also get the same on 2 x identical 6-node Hybrid arrays, random read IOPS differ by 200k and random write IOPS by 40k!The same X-Ray appliance was used on all clusters, using the default settings in the test itself.Just after a possible explanation to these queries, if somebody could be so helpful.Thanks very much.

Ubuntu Cloud Images are pre-installed disk images that are customized by Ubuntu engineering to provide Ubuntu Certified Images, Openstack, LXD, and other features in public cloud environments.Due to the pre-built image and customization the OS requires specific virtual hardware such as a serial port that AHV does not include by default. When trying to boot a VM on AHV from any of the Ubuntu Cloud images, the boot process stalls after loading the Btrfs module as the hardware is not there.This can be helped by customizing the VM manually using a combination of Prism and aCLI commands or by leveraging API calls.Download Ubuntu cloud image in .img format Upload as Disk to Prism Image Services Create a new VM and attach the disk created in step 2 as Type: "Disk", Operation: "Clone from Image Service", Bus: "SCSI" and for Image select the name of the uploaded image and then click "Add" Select "Custom Script" at bottom of the window (AOS 5.10.6 and later) and in "Type Or Paste Script" paste t

AHV creating disk with 4k physical sector size. I have a requirement to create 512-bytes sector size. Finding no options parameter with vm.disk_create. Is there any other way to achieve this requriement. 

I created a Project in Prism Central and assigned a bunch of users to it, expecting them to be able to provision their own VMs with cloud-init configs customised to their liking.I found this awesome example code https://www.nutanix.dev/code_samples/create-linux-vm-customised-with-cloud-init/ which shows it can be done with API calls, however, as a user in the Project, there does not seem to be any options in the PC UI that allow me to specify a custom script when creating a VM.Are custom scripts deliberately hidden when using Projects? How are my users supposed to customise their VMs?

I’m looking for a way to expand storage a 6-node VMware cluster (ESX 6.7 U3), adding one or more Storage-only node could be an option. But, as I know, Storage-only nodes come with AHV, so I’d like to understand how I could add those nodes to the existing cluster.Trying to picture the idea, I'm assuming that SO nodes would work as new storage pool and cannot be expanded the existing one, am I right? I'm looking for documentation that give me some direction about the idea I have in mind.Any idea about this?

Nutanix AHV is a bare metal Type-1 hypervisor developed by Nutanix. Nutanix AHV can be directly installed on any Nutanix certified OEM hardware server i.e SuperMicro NX, IBM CS , Lenovo HX , HPE ProLiant, Cisco UCS, Dell XC and many more being added along the way.AHV is built upon the CentOS KVM foundation and extends its base functionality to include features like HA and live migration, etc. Full hardware virtualization is used for guest VMs (HVM).In AHV deployments, the Controller VM (CVM) runs as a VM and disks are presented using PCI pass-through.  This allows the full PCI controller (and attached devices) to be passed through directly to the CVM and bypass the hypervisor. AHV does not leverage a traditional storage stack like ESXi or Hyper-V. All disk(s) are passed to the VM(s) as raw SCSI block devices. This keeps the I/O path lightweight and optimized.KVM Architecture:Within KVM there are a few main components: KVM-kmod KVM kernel module Libvirtd An API, daemon and manag

When you open the console window after assigning the GPU to the vm as Passthrough and turning it on, "guest has not initialized the display" appears.When changing to uefi -> bios legacy, the console screen is displayed. What is the difference and is there a way to do it in uefi environment?

We’re over a hump day, and I would like to share an insight that may come handy to those of you that upload binaries to their clusters manually. Did you know that you have seven days to use the upgrade package that you uploaded to the cluster manually before it is removed from the file system? That’s right. Even if you have triggered pre-upgrade checks for the version, but the package is not used it deleted automatically. Make sure to clean up uncompressed software location and check the /home space on a CVM before you re-attempt the upload.KB-10300 Uploaded AOS upgrade binary is unavailable on Prism has more information To wrap your head around upgradesAll things considered — upgrade sequence and preaparation guidelinesFoundation of a successful upgrade - up to date FoundationNutanix upgrades FAQ: AOS, LCM, NCC, Hypervisors, Files

The Acropolis Operating System (AOS) provides the core functionality leveraged by workloads and services running on the platform Building upon the distributed nature of everything Nutanix does, we’re expanding this into the virtualization and resource management space.  AOS is a back-end service that allows for workload and resource management, provisioning, and operations. This gives workloads the ability to seamlessly move between hypervisors, cloud providers, and platforms. Acropolis Services: It is an internal service which runs on each CVMAn Acropolis Worker runs on every CVM with an elected Acropolis Leader which is responsible for task scheduling, execution, IPAM.Acropolis Leader Task scheduling & execution Stat collection / publishing Network Controller (for hypervisor) Acropolis Worker Stat collection / publishing VNC proxy (for hypervisor) Above diagram shows conceptual view of the Acropolis Leader / Worker relationship Dynamic SchedulerEfficient scheduling of resou

When trying to move from esxi to AHV of a VM with OS Debian 10, I get an error This VM is not on the AHV supported OS list. To proceed with migrating this VM, please be sure to bypass guest operations and take care of installing AHV device drivers separately. This VM has a guest OS which is not supported on ESXi. Please remove the vm from the migration plan if migrating to ESXi. Is it OS not supported?

Volumes support ability to boot an Operating System over iSCSI for physical servers. In this configuration, a host can start a supported Operating System from a LUN instead of a Local Disk instance.This procedure describes how to configure Network Adapter BIOS Settings to enable this feature.Important Points:Refer to Intel Ethernet Adapter Vendor Documentation for more details about  Intel iSCSI Boot Configuration. According to Intel, we might be able to configure these settings through Adapter's Properties > Data Options Tab in Microsoft Windows Device Manager. Check Volumes Requirements and Supported Clients for a list of the supported network hardware and clients. Refer to Enable Nutanix Volumes and read about the procedures to perform on the Nutanix cluster. Before performing an iSCSI target discovery of the Nutanix cluster, configure BIOS boot settings for the network adapter as described in these stepsFor Step-By-Step Guide, Refer to Link

Many users try to periodically execute the NCC health checks as a good offensive tactic against any issues that might appear within their cluster, which is a great idea! However, rather than writing that down as a reminder somewhere or simply trying to remember to do so, many do not realize that this task can be scheduled right from within Prism.The task can be configured to execute as per the following schedules: Every 4 hours Every Day Every Week When choosing the every day or week options, you are also presented options to configure the execution according to a specific time of the day and specific days of the week respectively.What happens with the results when the scheduled NCC checks are executed? An email is sent to the email recipients configured within the Alert Email Configuration settings of the cluster.For more information, including the specific procedures for configuring this feature, please refer to the Scheduling and Automatically Emailing NCC Results section of the
