AHV supports GPU-accelerated computing for guest VMs. You can configure either GPU pass-through or a virtual GPU.   Let us say you have an AHV host with GPU compatible hardware and looking for a simple way to install the required drivers.  Nutanix recommends a specific method for installing the Nvidia GPU host driver in AHV hosts.  The method involves a script which is used for installation or upgrade of all the hosts in the cluster.   Go through the following document to understand the process in-depth    Installing AHV GPU Drivers    Have questions regarding the usage of the script?    What will happen if one of the nodes doesn’t have a GPU?   What will happen if the driver version is different on one node than the rest of the cluster?   How can I install the driver onto the new nodes only, without affecting the currently running nodes? Can I install different versions of the driver onto different nodes of the cluster?     The following knowledge base article can help you to

X-Ray is an automated testing framework and benchmarking application for enterprise-grade data centers. The X-ray application is a downloadable virtual machine (VM) with a user interface and complete documentation. Once installed, X-ray can test and analyze several different systems and report comparable information for your use. X-ray provides test scenarios for hype converged platforms that demonstrate variations in areas such as performance, data integrity and availability. Note: X-Ray is a tool for test environments and not intended for production environments.X-ray runs one test scenario per target at a time.Do not install the X-Ray VM on a cluster that you are using as an X-Ray test target, or a cluster that you are planning to use as an X-Ray test target. X-ray test scenarios: Availability: X-ray tests how a hype converged solution tolerates a node failure during a workload. X-Ray can measure how the failure of one node affects the availability of the whole system. Performa

I need some help for understanding Prism Central Image Management. When I read Prism Central Guide (Limitations) I don’t understand “During the copy operation, cluster A becomes unavailable.”This comment in Prism Central Guide mean that can’t use “cluster A” Prism Element ? Also that mean All acting is suspend like VM Provisioning Operation in "cluster A"?I want to know side effect and exactly what act is occurred using “cluster A” when becomes unavailable. Please help me.Thank you for your help :)

We’ve been recently exploring upgrading some code that interfaces with our Nutanix prism element from the v1 API to v3 and we are having issues retrieving the CVM from the v2 or v3 of the API.Looking at the response from the: /vms/ call on the v1 API we receive 10 total entries which include our CVM:v1 vms API resultv1 vms CVM resultYet when we make the equivalent API call on versions 2 or 3 we are only receiving 9 entries back and the result set does not contain the CVM:v2 vms API resultv3 vms API resultAfter searching through the API documentation nothing immediately stands out as an appropriate endpoint to get the CVM.  My question then is how do we retrieve the CVM when using the v3 or v2 API?

Files supports AOS software encryption and in-flight message encryption for SMB3 shares.You can only apply AOS software encryption to files by activating it through Prism. Refer to the file release Notes to ensure that you are running a compatible version of AOS. SMB3 Message Encryption: After enabling message encryption, the file encrypts messages on the file server side and decrypts them on the client side (only on the new connections for the share). Clients that do not support encryption (Linux, Mac, windows 7) cannot access a share with encryption enabled. Authentication: Active Directory with Kerberos provides secure authentication. File supports the following Kerberos encryption types. Advanced Encryption Standard 128 with the Keyed-Hash Message Authentication code and Cryptographic Hash Function SHA1  Advanced Encryption Standard 256 with the Keyed-Hash Message Authentication  Message Authentication code and Cryptographic Hash function SHA1 (AES-256-HMAC-SHA1) Rivet cipher

To update the directory services configuration, do the following:Procedure: Go to the File Server dashboard, click the File Server tab, select the target file server and then click Protocol Management Click Directory Services In the Directory Services window, select the protocols you want to use and complete the fields for the selected protocols. You can select SMB, NFS or both. Each protocol contains more fields to complete.      4.  When all the fields are correct, click the Update button. Authentication:Depending on the primary and secondary protocols configured for your file server, access and authentication configuration vary. File servers using SMB protocol must configure Active Directory (AD). File servers using the NFS protocol can use Lightweight Directory Access Protocol (LDAP), AD, or unmanaged authentication services. LDAPWhen you configure LDAP as the authentication service, Files uses Netgroups to control client access. The Files LDAP setup is based on the RFC 2307 st

Hi Team,Am a beginner in learning Nutanix, please guide me in getting understanding the below!. if we have a Esxi Cluster using Prism Element, we can manager the operations?each host in the Esxi cluster will have CVM!if we connected to <a.Esxi host> from the cluster to execute a command using "aCLI", why the commands, will pass to other CVM's (CVM - inside hosts)?

I have a 20+node cluster and 2 nodes had multiple hard drives go out between them ( 1 SSD and 6 SATA). They are all showing stuck. I do not see any replication happening when using this command: curator_cli get_under_replication_info summary=true.All nodes show up good when using this command:nodetool -h 0 ring | grep Normal Would it be a good idea to kill the tasks with this command:cvm$ progress_monitor_cli --entity_id="<Entity_ID>" --entity_type=<Package_Name> --operation=<Operation -delete 

Once we run out of the space while deploying new VM, why we need to Deselect Enable HA (it must be set within the limitations or Admissioin Control must restrict to deploy beyone the threshold), where the VM's going to reboot on other hosts (which will be a production impact)     

Hi All, I’m sorry if asking questions on group. I have new deployment with HPE DX360 via foundation portable 5.0.1 and flat switch but somehow it run into error and error message prompted during installation via foundation which im not so sure why. Im using foundation 5.01 and upload with aos 5.20. The foundation error log stuck here after sometime;StandardError: Failed to connect to Phoenix at 192.168.100.32021-06-28 06:10:50,703Z ERROR Exception in running <ImagingStepInitIPMI(<NodeConfig(192.168.100.3) @2190>) @8fb0>Traceback (most recent call last):  File "foundation\imaging_step.py", line 161, in _run  File "foundation\decorators.py", line 77, in wrap_method  File "foundation\imaging_step_init_ipmi.py", line 273, in run  File "foundation\imaging_step_init_ipmi.py", line 184, in boot_phoenixStandardError: Failed to connect to Phoenix at 192.168.100.32021-06-28 06:10:50,706Z DEBUG Setting state of <ImagingStepInitIPMI(<NodeConfig(192.168.100.3) @2190>) @8fb0>

Interested to test Nutanix Move on my CE installation in my lab. But I didn't found how to download it without registration on portal , that require real Nutanix serial number. How may I download Nutanix move? Please provide needed link.

Hi I’m new to nutanix with ESXi. I recently deployed a 4 nodes nutanix with esxi. I’ve created containers and add the nodes to the vCenter. I have not add the vCenter to the Prism. I check at prism and there’s a warning saying the hosts are not connected to vCenter. Anyone encounter this issue before? 

Hi I would Like to add 2 Different group of user from my Active Directory access Nutanix System. Can advice me the step i need to do in Nutanix System.

Just a quick question about sizing SSD capacity to HDD capacity in a node (in a new homogenous cluster). When specifying drive space in a node, what is the percentage SSD to HDD per node at a minimum. Is there a best practice guide that someone can point me towards? I’m not asking about the number of HDDs vs the number of SSDs.The question is around capacity and not number or drives. e.g. I configure a node with 4TB of SSD (2x1.92TB) and 60TB of HDD (10 x 6TB) and Nutanix Sizer says this is fine. This is roughly 6.25% SSD But what should I have as a minimum SSD capacity of of a hybrid node is 6% Okay, or should it be more like 10% or 20% (or more)?

We get some questions from customer. Our customer have several Nutanix units with several models including:NX-1365-G4 NX-1365-G5 NX-8235-G4 NX-6235-G4 NX-8135-G4The question is whether HDD can be replaced with SSD? What is the procedure and what about the data on the HDD? Thanks

Consider an application that requires very high IOPS, unattainable within the Nutanix environment due to the overheads of RF2 replication.  Can a raw NVMe front bay drive or workload accelerator be mounted onto a VM as a logical drive, and with no data replicated, in order to provide maximum performance.  Obviously it will be node locked, but this is acceptable,   Is this technically feasible?

Hello,I'm trying to execute a NC-Check via Ansible on all of our clusters, because till know it failed because of a missing firewall unlock.

We are implementing Nutanix with VMware. From a security point of view we want to monitor our new hosting platform. All other systems in the environment log to our SIEM product. Is there any guidance or can anyone give me some guidance on what to have switched on in the logging and to what level?

We are in the Process of expanding our 4 Node Cluster to 6 Nodes. The Installation of the Hosts was successful using the Foundation VM. However, the servers have Nvidia cards installed, so we need to install the driver as well. When the Cluster is expanded with the 2 extra nodes, my understanding of the command “install_host_package” is, that it will install the drivers on all hosts, that have Nvidia cards. Even those, that already have the driver. To do so it will migrate the VMs and put the Hosts into maintenance. This is not an option for us, since the reason we are expanding the cluster is that the current cluster already is overloaded. I am looking for a way to install the drivers without interfering with the up and running environment. For example, is there a way to install the drivers before expanding the cluster?

Use these firewall requirements to configure rules in your external firewall to allow Nutanix Remote Support, Pulse, SMTP, 1-click upgrades, and LCM updates. Source Controller VM / Prism Central IP addresses Destination nsc01.nutanix.net and nsc02.nutanix.net Protocol - Port TCP - 80 and 8443 Action ALLOW   Source Controller VM / Prism Central IP addresses Allows Pulse messages from the cluster to Nutanix support servers. Each Controller VM in your cluster collects Pulse configuration data continuously and sends Pulse metric data every 15 minutes to insights.nutanix.com over port 443 once every 15 minutes over HTTPS. Ports 80 and 8443 are the default ports that the cluster uses to connect to the Nutanix support servers nsc01.nutanix.net and nsc02.nutanix.net. Nutanix recommends that you open both ports. If one port is disabled, the cluster automatically tries to connect on the other. You can open the por

Can the CVM mount/create a new VMware datastore using NFS4 yet?

I have the latest version of Nutanix ERA installed in my lab and already have a registered Oracle server. From that server the template created without any problems and i can create new servers. But when i want to clone que existent server always fails wit: Driver execution failed. Error: 'NoneType' object is not iterable. Any ideas
