5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Hi, technically yes, both points are valid, you can use protection policies for Async replication with any license but you don’t get the advanced features such as orchestration, and you can operate Disaster Recovery from a single PC to which both clusters are registered. Obviously if you are going with a single PC it would need to be running on the target cluster not the source one.
You mean Nutanix Move? Move will attempt to inject drivers if you give it the right permissions but they may not be up-to-date. I would definitely recommend you install NGT (Nutanix Guest Tools) on the guest VM through Prism.
Hi Jai, for Disaster Recovery, you will ideally install a PC at each site for best availability. This will also require you to have either: Pro license with Advanced Replication add-on, or Ultimate license.
Hi, have you installed NGT? This should include the latest supported drivers.
There is no hard limit on vCPUs in a cluster – the limit is physical CPU cycles. Nutanix will manage prioritizing those cycles, but of course once you get to a certain utilization level, performance will be impacted because CPU queues will get long. As Moustafa says, your best bet is to add a scenario and see what it does to the predicted utilization.
Hi,Thanks for this, but I don’t believe an audit of “Folder” operations is the same as an audit of “Share” operations. In this case, the folder is basically another file, but it doesn’t help to see who shared that folder and when.
Hi Hendra, I don’t think there is any requirement to use anything greater than 10G for a Nutanix deployment even where NVMe is used. You may want to consider faster if you think the network could introduce unwanted latency, but this will depend on the nature of the workloads.
Hi Abraham,Just to add to the advice above, if the manual migration steps don’t help and there are AHV / KVM versions of these appliances available, you might find it easier to build fresh versions on the AHV cluster and then migrate the data (if required) between the old and new appliances.
Hi, just to confirm, your cluster has 90% RAM usage across all hosts, or just one of them? If it is across all hosts I would definitely prepare for some VM downtime to accomplish any maintenance on this cluster. If it is just one host, what is the utilisation on the other nodes, and based on that, is there sufficient available resource on them to accept the workloads from the hot node? If you don’t need another node (i.e. it is just RAM that is constrained) then you should arrange a maintenance window to do the upgrades and power off some or all of your VMs first. You may be able to identify non-critical workloads across all three hosts that when powered off give you sufficient headroom to keep everything else up during the maintenance operations, but you will need to be sure this is the case otherwise some of the VMs may not migrate.
Your list is different to mine - I can only assume Lenovo isn’t available as an option in your region perhaps?
Hi,First, I assume you have 25G capable NICs in the Nutanix nodes?I think the general rule of thumb is that DAC cables tend to only be supported for interconnecting same vendor kit. I.e. HPE will only support those Aruba DACs for connecting Aruba switches to other Aruba devices (or at a push possibly to HPE servers). Ideally you would use Aruba transceivers in the switch and appropriate transceivers in the NIC (so Intel / Broadcom / Mellanox or whatever the NIC happens to be) and then connect with appropriate cables. That said, most people will probably use the same optics at both ends (i.e. whatever vendor the switches are).Will DAC cables work? Almost certainly (in my customer days we used Cisco Twinax DACs between our Nutanix nodes and Nexus switches). Will HPE support it if there is a problem? Almost certainly not as they will only have been tested and certified for use with that vendors equipment.
Hey! In Sizer 6.0 you can switch between hardware vendors on an existing scenario in the Cluster settings - access by clicking “Modify” on either the Workloads or Solution pages: Then select your vendor from the dropdown: If you are creating a brand new scenario from scratch you will automatically get these cluster settings after creating your first workload, so just select the vendor you want at that point.
Hi, from the F5 support website:BIG-IP VE supports most KVM-based hypervisor environments (for example, Nutanix AHV, Oracle Cloud Infrastructure, or other third-party cloud platforms not explicitly listed here) as long as: You are using the BIG-IP VE standard KVM qcow2 or ova image from downloads.f5.com (v13.1 or higher) You are using the virtio networking driver (Note: SR-IOV may not be supported) You are using a standard BIG-IP VE license You or a third-party cloud/hypervisor vendor have not modified the base image to accommodate environment or hypervisor-specific customizations You are using the default i440FX machine type, when using F5’s virtio synthetic driver. The QEMU Q35 machine type is not supported. So you should be able to download a KVM OVA (or qcow2) image from the website for this.
Hi @jamiefki - This would actually be better done as an anti-affinity rule via the CLI (assuming you are AHV)? Otherwise known in the virtualisation world as a keep-apart rule:AHV 6.1 - Configuring VM-VM Anti-Affinity Policy (nutanix.com)
Hi @SantoshBavkar - I assume you mean two separate Nutanix clusters, one running AHV (the source) and one ESXi (the target)?Assuming this is correct you can setup DR between the two clusters and failover the workloads from Cluster A to Cluster B (cross hypervisor DR is supported). Assuming you don’t have AdvRep licenses this is done through Protection Domains in PE - you will have to manually start all VMs in the target cluster once the PD has been failed over so could be quite disruptive.PD-Based DR 6.1 - Nutanix Cross Hypervisor Disaster Recovery
Hi, I assume the move to Nutanix is to AHV? How did you migrate the VMs? As long as the VirtIO drivers have been pre-installed it should retain static IP information in most cases. As Steve pointed out, certain types of adapter might end up being disabled/hidden post migration if the source adapter is not a standard type.
Just resurrecting this thread based on recent experience with one of our customers: Nutanix categorically do not support CPU upgrades on clusters that are under maintenance. This has been confirmed by the head of support.
Hi Arun, thanks for the update… I seem to have intermittent issues like you say, can mostly see my existing scenarios (but occasionally the list goes blank again), still unable to create new scenarios though it seems...
