Hi While troubleshooting a performance issue with some VMs on the cluster, we noticed that the cluster-wide latency, as shown in the Prism graph on the front page, was around 23ms on average. This is significantly higher than our usual 10-12ms. Upon further investigation by support, the issue was traced to two VMs with high I/O activity, writing large blocks of data (over 1MB in size). To troubleshoot, we added the following graphs for each VM: Storage controller bandwidth (MB/s) Storage controller latency (ms) I have a few questions: Why is the term “bandwidth” used instead of “throughput”? My understanding is that bandwidth refers to the capacity (size of the pipe), while throughput is the amount of data passing through it per second. If the average cluster latency is high, wouldn’t this impact other workloads? Does the term “storage controller” refer to t

Hi,I am checking out Nutanix as a hypervisor. I understand however from our technical supplier that Nutanix will not be able to scale a GPU server using a storage server. Namely, I have a GPU server with some limited storage, which I would like to extend with a storage server(s). These would then be linked through a dedicated switch to the GPU server.He tells me that Nutanix is not good for that, and that we would have to go with VMWare. I understand that this has to do with hyperconverged infrastructure (HCI). However, I cannot imagine that Nutanix does not have a solution for such use-case. My question therefore is: can a GPU server be extended with a storage server using Nutanix?Thanks!

Does anyone have any documentation on the upgrade steps for nutanix firmware with LCM? I want to perform a firmware upgrade on my Nutanix cluster.

Hi TeamI am trying to create a VM in a specified container by using Prism Central V3 API. I am passing the container details in the storage_config → storage_container_reference of the payload. But what i observed that the VM is always getting created in the SelfServiceContainer.I am using Nutanix Community Edition.AOS : 6.5.2 LTSPrism Central : pc.2022.6.0.11Can you please let me know why new VMs are not being created in the specified storage container and instead end up in the SelfService Container despite passing the correct container UUID in the VM creation API payload? ThanksAkash

Hello,I’m somewhat new to Nutanix and have a lot to learn obviously.  I think this is my first post/question.We have an old cluster running a single VM for Prism Central that used to work for a 3 node cluster.  I cant recall when it stopped working.  The cluster is fine, the nodes are fine, Prism portal on each node runs fine.My thought… Q1) Does the Prism Central web service require credentials to start properly (see orange highlight below)?  Maybe I somehow need to reset the nutanix or root passwords that the HTTP service is trying to use/connect?Q2) Any other tips to try to help get PC working again?Q3) Can I simply de-register the PC from the cluster, then try to redeploy a new one or over top of the existing one?  Would that process have an impact on the VMs currently running in the cluster? Prism Central Status from PE = Disconnected Warning : PE-PC Connection Failure Nutanix v5.17.3 NCC v4

I am doing 4 node AHV cluster decommission. I did all the steps and finally gave cluster destroy and ensure it was destroyed completely. I want to do a factory reset of all the nodes where the hypervisor /CVM configurations like hostname, IP etc will be wiped out. Please let me know the procedure for this. Thanks.

I recently built a Nutanix CE 3-node cluster on ESXi. The cluster’s up and I want to add a 4th identical node so I can replace node 1 (I have another thread on the disk skew issue I’m seeing there), but the precheck cassandra_ssd_size_check fails when preparing to add the new node (SSD tier on nodes [u'xx.xx.xx.xx'] is not sized to accomodate expected metadata growth on cluster).I wonder if this is a bug because the same NCC Health Check (cassandra_ssd_size_check) runs every hour on the cluster without any problems, and the new node is identical in its disk sizes to the existing nodes.Is there a log somewhere that would tell me what it checked and how/why it failed?Is there a way to verify which disk was assigned to Data and which to CVM boot during install? All of the commands I can thus far locate just tell me info on the virtual disks.

Currently, i see that prism java client and other java libraries with version of 4.0.1-beta-1 are dependent on spring-boot (2.5.14). Since it includes many vulnerabilities, is there a version with the latest springboot version or version above 3.0? Thanks

I am preparing for Nutanix NCA 6.5 Exam, can someone tell me Nutanix test drive is free for practice or not?
