Hello guys,Is it possible to extend ACI VxLAN to Nutanix AHV OVS (using Opflex agent maybe), in other words can we integrate it to ACI ?

I can ping to AHV from my pc. I can ping to CVM from AHV via address 172.x.x.x  and internal address 192.x.x.x But I Can Ping To CVM From My PC.

Want to know the maximum number of VLAN(802.1q) interfaces than can be created on each bridge of AHV. I cannot find any documentation or matrix about this. Thank you.

Recycle bin feature is available from AOS 5.18 onwards. With help from Nutanix Support, the recycle bin tool helps you to restore deleted storage entities (guest VMs and volume group vDisks) and manage the recycle bin itself.After you delete a guest VM, the configuration file and disk remain in the recycle bin for up to 24 hours. After 24 hours, these files are deleted. The files are deleted in less than 24 hours if your cluster is unable to maintain sufficient free disk space.Recycle Bin Limitations and Guidelines The recycle bin stores vDisk and configuration data for up to 24 hours. After 24 hours, these files are deleted. The files are deleted in less

How do I check hot and cold data by virtual machine? I'm going to migrate the virtual machines of the existing nodes to the node that I'm going to buy new ones. So, I'd like to check the hot and cold data of the virtual machines, respectively.

We have 3 nodes with 2x960GB SSD and 4x4TB HDD.We need to expand storage (and storage only as it is going to be used to store cold data - we do not need additional processing power or RAM)Question 1: We simply added two 12TB HDDs to each node. Now each node has 2x960GB SSD, 4x4TB HDDs, 2x12TB HDDs. Everything is working fine, but we were told that this is not recommended. What is the problem with this configurationQuestion 2: Assuming the configuration in Q1 is not recommended and we want to end up with each node having one type of HDDs. We were told that we can upgrade the existing 4TB HDDs with 12TB drives. What the right procedure would be:  a) Mark one 4TB drive for removal, remove it, insert 12TB drive in place of removed 4TB drive. Repeat 4 times for a node. Resulting configuration - 6x12TB HDDs per node  b) Add two more 12TB drives first, then mark for removal and remove four 4TB drives (one by one). Resulting configuration - 4x12TB HDDs per

Hardware failures are a part of any datacenter lifecycle. The Nutanix architecture was designed with this inevitability in mind. A cluster can tolerate one or two failures (depending on the replication factor of the cluster or container) of a variety of hardware components while still running guest VMs and responding to commands through the management console. Many of these failures also trigger an alert through that same management console in order to give the administrator a chance to respond to the situation.Nutanix provides the ability to tolerate rack failures for extended data availability, in addition to drive, node, block, and network link failure.Block fault tolerance lets a Nutanix cluster make redundant copies of data and m

Failures are part of everything and Nutanix Clusters is not immune to it. But how we plan for failures determines the versatility of the product or a person for that matter!!Nutanix categorizes the type of failures into availability domains essentially based on type of failure. Nutanix provides the ability to tolerate rack failure for extended data availability, in addition to drive, node, block and network link failure. Node FailureA Nutanix Node comprises Physical host and a controller VM. Both these components can fail without any impact to the Nutanix cluster.CVM failureWhen a CVM fails, an a

Hi folks, In VMware, we need to enable EVC to be able to do vMotion between diff processors, what about AHV? what should be done or is it working smoothly?

NVIDIA GPUs primarily have two modes of operation: Compute and Graphics.Compute Mode: the GPU operates within a configuration that is optimized for high-performance computing applications.Graphics Mode: the GPU is optimized for graphics processing and can subsequently be assigned into vGPU profiles for virtual machines (vGPU profiles cannot be used while in compute mode).Various NVIDIA GPUs are provided with default configurations for either of these modes and, sometimes, it is necessary to change the mode to better suit the corresponding workload of the host.In previous models of GPUs, it has been necessary to temp

We have numerous clusters and each have their own hardware platform (and in a couple of cases, we’ve even mixed hardware models within the same cluster). Our current Nutanix footprint;VENDOR         MODELS        NODE COUNTSuper Micro    NX-8155-G7    12Super Micro    NX-1175S-G6    7Super Micro    NX-3060-G7    6Dell                 XC630-10         14Super Micro    NX-8035-G7    12Super Micro    NX-8035-G6    36Is there a preferred or recommended solution for hardware monitoring and alerting?

Nutanix Era is a suite of software which automates and simplifies database management, bringing one-click simplicity and invisible operations to database provisioning and lifecycle management (LCM). Starting with Copy Data Management (CDM) as its first offering, Nutanix Era enables database admins to provision, clone, refresh and restore their databases to any point in time. Through a rich, but simple to use, UI and CLI, they can restore to the latest application-consistent transactionEra enables you to easily provision database environments (either production or otherwise) on your Nutanix clusters. Also, you can only provision the database server VM that hosts a database, so that you can later create or clone databases on that database server.Some of the components include

 A single-node cluster is configured like a regular (three-node or more) cluster in many ways, but here are some of the conditions. Nutanix offers the option of a single-node cluster for ROBO implementations and other situations that require a lower cost option and accept lowered resiliency protections. Single-node clusters are supported only on a selected set of hardware models. Refer the following article for details single-node-supported-hardwares Do not exceed a maximum of 1000 IOPS

From the Nutanix Bible: “when a Curator full scan runs, it will find eligible extent groups which are available to become encoded. Eligible extent groups must be "write-cold" meaning they haven't been written to for awhile”.I have 2 questions:if I have some data just written in the oplog, how long takes to copy those datas in the extent store, assuming that there is not any read of it?Once the data are in the extent store, how long it takes before the erasure coding is applied to the datas? 

Is there a command to update a vm’s custom script/user data?I tried the following and it doesn’t work:<acropolis> vm.update  my-vm cloudinit_userdata_path=file:///tmp/user-data.txt

Use the Data Services IP method for external host connectivity to VGs. For backward compatibility, you can upgrade existing environments non disruptively and continue to use MPIO for load balancing and path resiliency. For security, use at least one-way CHAP. Leave ADS enabled. (Enabled is the default setting.) Use multiple disks rather than a single large disk for an application. Consider using a minimum of one disk per Nutanix node to distribute the workload across all nodes in a cluster. Multiple disks per Nutanix node may also improve an application’s performance.

Are there ANY plans to expand on the PowerShell cmdlets at all, specifically for getting host info? They’re pretty bare bones. I don’t even know the last time the cmdlets were updated/expanded. It seems to me Nutanix regrets making them and hopes they will quietly die. I have relied heavily on PowerShell to keep tabs on a very large Nutanix environment running Nutanix on both AHV and ESXi. I’m talking 700+ nodes. The ESXi clusters are no problem getting the info from because I use VMware’s PowerCLI to supplement the lack of data I can get with Nutanix Cmdlets, but the AHV clusters are another story since I don’t have PowerCLI to fall back on. Can we at least get a cmdlet that will allow us to use PowerShell to initiate ncli or acli commands, like VMware does with the “Get-EsxCLI” cmdlet. That would be very helpful.

I’m sure you have seen that one before. In most cases you expect it or at least understand what caused it. In some instances you probably ignore it (we all do, no shame). What if this happens when you log into the CVM or the host? Has cluster security been compromised?During the upgrade or rescue of the AOS new keys are created for each node in the cluster. When you open SSH session, these keys are compared to those that were noted on the client previously and since there is a mismatch a warning is triggered.KB-2388 Upgrade/Re-install of AOS changes the ssh key for remote host identification explains how to clean up the keys to get rid of the warnings.

Hi Community,Version and model - NX-1065-G6I have a faulty DIMM in one node.  Memory | Uncorrectable ECC (@DIMMC1(CPU2)) | AssertedI would like to remove it from the node and restart it. i.e. Not to replace it with a new memory module.Is this possible? Risks? How should I configure the node with the missing DIMM, or is it something that Nutanix takes care of automatically? Any other advice? Recommendations?I found this document. Is this the correct one to follow?Cheers!

Hi,We are planning to move to Nutanix in our organization. One of the application that is in the scope of this project is Splunk. We are a small environment and our Splunk data intake is around 30GB/day and the setup is mainly used as a SIEM.We have received a few recommendation to isolate Splunk to a separate cluster. Is this necessary, or can we have it on the same cluster if we could guarantee the availability of resources for it? The cluster will host a few application and some infrastructure component like AD and DNS.Are there any major benefits if we isolate Splunk in a different cluster?
