Objects Browser

The Objects browser is a User Interface (UI) that allows the users to directly launch the object store instance in a web browser and perform bucket and object level operations. This eliminates the steps of logging into Prism Central and launching the Objects service. The administrators use Prism Central to manage the object stores. When an administrator creates an object store, a default bucket (object browser) gets created. The static website hosting capability is already enabled on this default bucket. The Objects Browser UI is hosted on this default bucket is created The administrator can share the object store URL with the user to access the Objects Browser UI. The URL can be formed using the Objects Public IP addresshttp://objects-public-ipaddress/objectsbrowserYou can use http or https to access the web-browser Administrator workflow:The administrator needs to perform the following steps to grant access to the Objects Browser to a particular set.To grant access to Objects Brows

Where is the v3 API for migrating disks?

https://www.nutanix.dev/reference/prism_central/v3/api/vms/postvmsuuidmigratedisks/ describes an API to migrate disks as vms/{uuid}/migrate_disks. But the API is not available in AOS 6.0. I got the following response{ "message": "The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again." } The swagger definition from the cluster does not contain the endpoint either even thought the definition “migrate_disk_input” is defined. The cluster has the following information: "config": { "software_map": { "NOS": { "status": "INSTALLED", "version": "6.0", "software_type": "NOS" } }, ...

Configuring Network Switch Information

About this taskTo track and record networking statistics for a cluster, the cluster requires information about the first-hop network switches and the switch ports being used. Switch port discovery is supported with switches that are RFC 2674 compliant. Switch port discovery involves obtaining statistics from the Q-BRIDGE-MIB on the switch and then identifying the MAC address that corresponds to the host. Such discovery is currently best-effort, so it is possible that, at times, an interface might not be discovered.Before you beginBefore you configure network switch information in the Prism web console, configure the corresponding SNMP settings on the first-hop network switch.About this taskTo configure one or more network switches for statistics collection, do the following:Procedure Click the gear icon in the main menu and then select Network Switch in the Settings page.Note: Network switch configuration is supported only for AHV clusters.The Network Switch Configuration dialog box ap

Cisco Switch for small deployment - which one to use ?

Hello,I´m new in this forum. In fact I´m new in the Nutanix world. We currently have a traditional VMWARE cluster with traditional FC SAN Storage and Catalyst 3850 switches (7 servers).We are planning to replace it with a brand new solution based on NUTANIX (with 6 nodes or so) but using VMWARE as hypervisor. The question that arise are:We need to install 2 new “top of the rack” switches for NUTANIX connections. If using Cisco (and taking into account our proposed cluster size) which one could we use ? I mean, Catalyst 9300 are ok ? Or they have to be the more expensive Nexus ? To reduce initial costs we are planning to keep the Cat 3850 to act as coreswitch and also because we need to conect other devices, but we need to ones for the new nodes. Our current VMWARE Servers have 2 x 10G connection for DATA/VEEAM BK and 2 x 1G for vSphere MGMT/vMotion. In order to cope with data traffic but also with “disk sinc” traffic, should we provide the new nodes with 4 x 10G (2 for DATA/veeam BK

DAG and nutanix replication

hello all i am in this tight situation. as i have AOS PRO license i only can do is Async replication but i really need to make the RPO 0 so, i am thinking to leverage application level replication. for example in exchange application I want to leverage DAG replication method to be able to sync both main and DR site with RPO=0so my question if i do this configuration and take out my exchange server from any protection domain, do you think Nutanix would still give me support if the replication process have a fault after time?

AHV GPU Series | Installing Nvidia grid virtual GPU manager

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?

Sizing SSD capacity to HDD capacity in a node

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)?

Installing Nvidia host drivers before Cluster expand

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?

Objects LCM Upgrades

Objects version upgrades by using LCM feature. You can perform LCM upgrades through Prism Central (PC). Objects is a part of the PC upgrades module in LCM. LCM upgrades the following components of Objects: Objects Manager and Objects Services.Objects ManagerObjects Manager is a containerized service running on a PC VM. The objects manager is primarily responsible for taking input from a user for deploying the object store, validating the user inputs, managing certificates, deploying the Objects Services and serves as an interface between PC and backing object store. A single Objects Manager can manage one or more object stores. In case of scale-out PC, the Objects Manager service runs on each of the PC nodes and provides high availability.During the upgrade of the Objects Manager, no disruption happens to the Objects IO. However, the user interface will not be available for a short period of time for statistics and management.Objects ServiceObjects Service provides the object store int

RE-IP and add VLAN to CVM and AHV

HI all, I'm preparing a change on the cluster (6 node cluster running AHV). I need to re-ip cvm's and ahv's and add them to a specific vlan (now they are not in a vlan). Before I do this in production I decided to do this on the test lab. (old baby, 4 node G5). I've followed this guide: https://next.nutanix.com/installation-configuration-23/physical-relocation-of-nutanix-clusters-38403 but got stuck step 7 after booting the cvm's. The ouput of svmips shows the old cvm ip's but they are all booted with the new ones. (and accessible via ssh on the new ip's)The output of hostips shows the old ahv ip's byt the are all booted with the new ones. (and accassible via ssh on the new ip's). I must also say that the external_ip_reconfig script hangs at a specific time and now the command “cluster start” gives an error the the cluster is still in reconfigure mode.
