How It works

Just a basic quick question I’d like confirmation on if possible. In a Nutanix Metro availability configuration (ESXi stretched cluster stretched across two sites) do all the CVM’S from both clusters have to be on the same Layer 2 Network to be supported?

HiI'm hoping someone has a similar setup.  I originally posted this question a month or so ago but the answer I received isn't correct.  The post has been marked as solved so I'm unable to reply hence why I'm opening a new one.  I think  there was a misunderstanding  with my  described setup in the previous post so I've tried to make it clearer here.  This is tricky to explain without diagrams so I appreciate this may be difficult to provide a valid answer and I may not get a response.Our SetupWe have a 2 sites connected by fast links with one Nutanix cluster at each site (16 nodes in each Nutanix cluster).  These two Nutanix clusters make up 1 stretched ESXi cluster hosting mainly Window servers.  We then use Metro availability to replicate between these sites\Nutanix clusters.So in short - One ESXI cluster that's stretched across two sites and we use Nutanix Metro to synchronously replicate.On this environment we host a number of VM guest failover SQL clusters (2 nodes in each cluste

Sometimes you have to mount an ISO, and historically, the only methods to achieve this on G6 and G7 platforms were:  1) by using the IPMI Java console or 2) by mounting the ISO directly from a CVM (KB-4616) With BMC 7.11, we have an added option to mount the ISO directly from the HTML5 IPMI console.  For more details, please check out BMC 7.11 release notes and upgrade today for this and many more new features and security enhancements!

Has anyone been able to enable bitlocker on a drive within Server 2019 or 2022? Or is there an update regarding this article? Bitlocker cannot be enabled on Windows Server 2019 in VM running on AHV (nutanix.com)

Hello,I need to create several Windows Server 2019 standard, virtual machines that run in AHV (Nutanix cluster of 3 nodes nx-3170-g8, with 2x16 cores in each node) hosts that i need to buy licenses for. But i do not seem to find a calculation method for licenses).I found that i can go for per core licensing of physical cores (3*2*16 = 96 cores) which would help reduce costs since the total number of virtual cores that need to be configured is more than 200 v-cores.i would like to confirm if this approach is correct? i.e. licensing the number of the physical cores of nutanix appliances? and if anyone did it successfully?Thank you in advance,

New to Nutanix and trying to understand HA for management like in VMware.  In VMware we setup vCenter HA with an active/passive/witness.  Is there something similar in Nutanix?

HiI'm hoping someone has a similar setup.  We have a 2 sites connected by fast links with one Nutanix cluster at each site (16 nodes in each cluster).  We use Metro availability to replicate between sites.  We have 1 stretched ESXi cluster hosting mainly Window servers.We have a number of VM guest failover SQL clusters (2 nodes in each cluster)  which require shared storage and therefore require the use of Nutanix Volume groups.  Each VM is connected to the volume group via ISCSI.We can't use Metro replication to replicate these VMS and their associated volume groups to the other site as you can't replicate volume groups with Metro availability - it's not supported.So, the only other option is to use Async replication.  Here are my questions:In the manual the conditions for Async say  "Do not have VMs with the same name on the primary and the secondary clusters. Otherwise, it may affect the recovery procedures"Q: If we failover the async protection domain containing the cluster node VM

Hi All,I want to test block storage, file storage and object storage. How many nodes are needed for the minimum cluster size? Is there a recommended configuration？

We keep our test cluster up-to-date with the latest STS versions.Unfortunately, by doing so, I cannot upgrade from 6.0.2.5 to 6.1 as it is not supported.Upgrading from 6.0.2.4 is supported.I have two questions, one, when will I be able to upgrade to 6.1 from 6.0.2.5?Second, should I lag a version or two behind in the STS track to make sure I am not blocked from taking a major upgrade?Thanks!

Hi We have 2 sites with fast links between them with 1 Nutanix cluster on each site.  All the hosts are running the ESXi 6.7 hypervisor. We use Metro availability so we have 1 ESXi cluster stretched across both sites. Currently Prism central runs on a VM in located on hosts in the primary site in a Metro availability enabled container\DS.  We looking into scaling out our Prism Central installation from 1 node to 3 nodes. Ideally I was thinking we could spread the Prism Central nodes across the two sites, perhaps by having 1 node on site 1 and 2 nodes on site 2. However, the Prism Central scale out manual states the following: “All scale out Prism Central VMs must run on the same cluster. For example, running two VMs in cluster_1 and one VM in cluster_2 is not supported".   Is this referring to one ESXi cluster or one Nutanix Cluster - I just want to be sure? Thanks in advance.

If you’ve ever encountered an alert like the referenced one below, you might have wondered, “What does this alert mean, and what do I do next?”Reference Alert:1 DIMM RAS event found for P1-DIMMA1(Serial:XXXXXXXX) by Samsung on host x.x.x.x in last 24 hours. Installed BIOS version is PB42.602The answer to the first question is easy.  RAS stands for Reliability, Availability, and Serviceability and is an advanced feature that is enabled in the server’s BIOS to detect and alert failing memory region(s) proactively. The second answer is a bit more tricky, but don’t worry, we’ve got you covered with KB-11794 which goes into detail about how to diagnose and resolve a RAS event, and KB-7503 which covers DIMM error handling guidance for G6, G7, and G8 platforms.
