Can we define a kind of "VM class" in a Nutanix cluster?

I would like to know if there is a way to define a kind of "VM class" in a Nutanix cluster, similar to what I can do with VMware's resource pool. The objective is to limit excessive CPU and IOPS usage. My goal is to have CPU classes like 'bronze, silver, gold' and the same for storage.If you have any information, I'd like to hear from you.Thanks in advance

Volume Groups - Which API v3 or v2 & Ansible Module Nutanix NCP

Hello Everyone  I have been building Ansible Playbooks to automate Nutanix VM builds and I have the need to create and attach a volume group to some of the VM’s.  The Nutanix NCP module from Ansible Galaxy has been pretty much the only module I could locate that really handles the vm creation well.  What I have found is that depending on where you go there are conflicts in whether or not version 3 or version 2 of the API is supported.While using the API explorer on Prism Central it is shown as volume_groups and appears exposed.  When reviewing docs and next.nutanix, various API information it appears it should work but doesn’t and I can’t seem to locate any good examples.Anyone here willing to share code or direction on what they have working for volume group creation and management.  I am currently on working with 2 clusters with Prism Central deployed.  I am hopeful I can find a functional example of ansible or api calls that manage volumes and thank anyone in advance for their help.

Cluster DOWN. Unable to access IPMI because lacked of credential

I got an issue where the cluster is DOWN and I unable to access the CVM and AHV via SSH. I have requested for credential to access IPMI, but they do not found any valid credential to access IPMI, even with a default password. There 4 nodes in 1 block, which I only have an access to 1 node [CVM and AHV]. I also unable to access the Prism. Is there any possible way to UP the cluster? Besides, I unable to create case to support.

What is ICAP and integration with Nutanix files

ICAP stands for internet content adaption protocol is an open standard being adopted to connect devices to enterprise-level virus scan engine . same way with the nutanix files is to enable communication with external servers hosting third-party anti-virus software to scan inbound data (files) in transit via Secure Proxy before sending it to the backend destination server.ICAP WORKFLOWThe ICAP service runs on each Nutanix Files file server and can interact with more than one ICAP server in parallel to support horizontal scale-out of the antivirus server. The scale-out nature of Files and one-click optimization greatly mitigate any antivirus scanning performance overhead. If the scanning affects Nutanix Files FSVM performance, one-click optimization recommends either increasing the virtual CPU resources or scaling out the FSVMs. This feature also helps both the ICAP server and Files scale out, ensuring fast responses from the customer’s antivirus vendor WHY Nutanix files integration with

How do I know if my hard disk C is full?

I made an alert for the hard disk, if its use reaches more than 90%, it sends me an alert on the e-mail, but the problem is that some servers contain a C disk and a D disk, and when one of the disks is full, it does not send me an alert because the other disk has space, so how can I separate the disks from Some in order to warn when any disk is full of them

Converting BR1 to VS1 without reboot?

Good afternoon AllI have just watched a video about converting Br1 to VS1, during the process it shows that the hosts will go into maintenance mode and reboot, however the presenter said that unless the MTU is altered the VS will be created on all hosts with no reboot - I just want to confirm this is correct as this is a live production environment? Many thanksEric

Has anyone used Mikrotik switching for a Nutanix cluster?

Subject says most of it. I have read the physical networking “best practices” guide, and I am currently running a small (3-node, NX-1175S-G7) cluster on top of Dell S4112F switches.My org is looking to add a second cluster at a second datacenter, and I was asked if the Mikrotik CRS510-8XS-2XQ-IN or Mikrotik CRS518-16XS-2XQ switches would work for the new cluster.My initial response was “no,” but I’m wondering if anybody has tried it? I would be concerned about buffer size on the switches… but how much does that matter if all of the cluster nodes are connected at the same speed, and I have a L3 boundary (router/firewall) between the VM subnet and the rest of the network (router has much better buffering than any switch would)?I do not have decision-making power here, so how can I “influence” my boss that using three-figure switches is likely to be a problem for a 5-figure+ cluster?
