Let's Talk About Tech!

Background There we go, you have been able to deploy a Nutanix CE instance for your lab/testing environment. You would like to set some backups up ? You also have some Rubrik deployment and you would like to take benefit of this environment ? This is totally making sense but you cannot add your CE cluster because of the AOS version incompatibility ? There is a way to overcome this - at your own risks !

Background Trying to upgrade to the latest AOS, NCC, Hypervisor .... but you are running out of space on your cluster and pre-checks are failing ? There is a fix !

Background Nutanix CE edition is not able to find a suitable NIC on your brand new Intel NUC G7. Do not worry, there is a workaround. This is an issue with the driver version and the hardware embarked within the Intel NUC G7.

Background Sometimes, you need to create multiple clones for a single gold image (template). This can be boring using the Prism Element UI if you have more than 10. Hopefully, there is a set of commands that can be initiated from the command line ACLI - Acropolis CLI. ACLI is rich in terms of action that can be done. Actually almost everything VM related can be done using ACLI. Here is how to create clones from a source VM.

Background When deploying a Nutanix CE host, the host name is always weird and random. Something like "NTNX-010422a0-A". This is not easy for maintenance - especially when you have more than one host. You probably would like to call it with the matching name of your real host like NUC-1, Host-1. This is not complex here is how.

Background Most of the time when deploying Nutanix CE, the hardware is limited because you need to save costs. Then, maximum RAM is limited - like in the Intel NUC who can only support up to 32 GB. By default, the CVM are configured with 16 GB RAM, therefore this is giving less RAM for creating VMs. If you are not using advanced features like dedup on the flight or erasure coding, you can decrease the CVM memory to 8 GB without any impact on the cluster. This is what this guide is all about.

Nutanix You all heard about Nutanix right ? Nutanix is a software company who creates HyperConverged Infrastructure (HCI) solutions that enable easy IT in your datacenter and in the the cloud. More details on www.nutanix.com . Beside the commercial product, there is a free  edition called the Community Edition  where tons of people contribute to the success of it. This freed  edition works on very low end hardware such as Intel NUC or refurbished servers that may lay around in your datacenter stock (if they have the relevant VTDx CPU features enabled).
