How It works

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)

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?

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?

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

Data Avoidance technologies typically contribute the most to data efficiency because they prevent the creation of unnecessary data, which also minimizes the need for more resource-demanding data reduction technologies. With fewer back-end operations, more resources are available for front-end (user-driven) operations and applications. As Nutanix enables its built-in data avoidance technologies automatically, there is no need for manual configuration or fine-tuning.Thin ProvisioningThin Provisioning is a simple and broadly adopted technology for increasing data capacity utilization by overcommitting resources. Nutanix enables this feature in all containers by default. In deployments using the VMware ESXi hypervisor, containers are presented to hosts as natively thin-provisioned NFS datastores. Although it is a widely accepted method for increasing capacity utilization, thin provisioning traditionally has been associated with reduced storage performance. However, on Nutanix, thin provisi

I run a 6-node nutanix cluster, and planing to run some containers (LXC) , inside VM using ZFS pool, to leverage on easy clone, migrate, snapshot the containers mainly to transport those clones to other system (DR) I read that ZFS need to deal directly with disks hardware to be sure about what is or what is not actually written to disks.  Is ZFS suaitable or not, being run on top of nutanix platform, concerning the data corruption risk or losing pool, because it can’t deal directly with disk hardware? Hardware is supermicro bundled with nutanix-enterprise.

Do you think is there any way i can migrate data from standalone server to the AHV?

Hi,I have three identical nodes (basic Lenovo servers) but one performs really slowly compared to the others. The disks aren’t the same across all three though. I wonder if anyone has any ideas which difference might be causing the performance issues: Firstly the HDDs are 4TB in the two ‘good’ nodes and 2TB in the ‘slower’ one. I wouldn’t expect that to cause performance issues, just overall capacity will be limited? To be fair the 2TB is a WD ‘green’ and the 4TBs are WD ‘red’ drives. Secondly the ‘slower’ host has a Samsung Pro 840 256GB SSD which Prism reports as often having a higher latency than the HDDs! See the image below  Are they known for being poor in this kind of environment? I’m not really stressing them. Any good logs to see performance issues? I can see the HDD activity light is permanently on on the slower host. Cheers,Steve
