5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Working using CLI is easy, simple, elegant and fast. Every administrator loves scripting and automating tasks using the command line. Nutanix makes Management tasks related to virtual disks easy, simple and efficient using CLI. So, what are the situations in which you might need to perform VM Disk management actions if you’re an administrator? You created a VM with a disk of 250GiB and now you need to increase it to 500GiB What if you need to increase the size of a VM Disk? Created a Disk but now need to clone it to different VMs! Need to create an image from a VM disk? Created a VM with the wrong BUS Type! Do we need to change the index of IDE disk? We all have faced a situation in which we might need to insert an ISO to a CD ROM or eject a CD ROM We have created a Volume Group and now need to manage the disks in the VG Most of these actions can be performed using the Prism GUI but what if we are more interested in CLI approach and want to automate these day-to-day admin tasks Do we
Every modern architecture solution requires data saving and optimization techniques to manage their workload efficiently and optimally. Nutanix HCI provides various techniques for storage optimization based on your workloads. Let us take a look around regarding the techniques to understand the working and best practices. 1. Compression There are two types of compression available Post-process compression Inline compression Want to know how compression works and how to enable it in your cluster? Compression Guide 2. Deduplication Deduplication reduces space usage by consolidating duplicate data blocks on Nutanix storage. Want to know more about different types of Deduplication and the best practices of using Deduplication? Deduplication 3. Erasure Coding Erasure coding increases the usable capacity on a cluster. Instead of replicating data, erasure coding uses parity information to rebuild data in the event of a disk failure. The capacity savings of erasure codin
Let us consider a scenario where you are running specific workloads that require extensive video rendering and needs GPU-enhanced acceleration. Nutanix provides a solution in which the hardware is configured with GPU cards that allow video rendering to be passed through to the User Virtual Machine. Want to read about NVIDIA Grid vGPU on Nutanix? The following guide will help in understanding the architecture and requirements of handling it. Nvidia grid vGPU Guide So which hypervisors support this implementation? The following hypervisors support the implementation : AHV VMware vSphere Microsoft Hyper-V The following document lists the hypervisor implementation in-depth for a vGPU solution. vGPU on Nutanix: Hypervisor Implementation. Have a GPU in your NX environment but wondering regarding the configuration, drivers requirement and basic troubleshooting? Go through the following articles to understand some basic troubleshooting steps, command
Let’s say you have Nutanix cluster with 24 CPU cores and 2 sockets and now you’re confused regarding the terminology. vCPU and cores per CPU and how to provision CPU to a Virtual Machine confusing you? Let’s break the terminology down in simple terms!In the world of Hardware, we have sockets and cores. In a host, there would be 2 sockets(or CPU) and 12 cores in each socket, resulting in 24 cores.So what is a vCPU?vCPU corresponds to the number of sockets for the VM. Cores per vCPU correspond to cores in a socket, so in conclusion, if you have provisioned your VM with the following configuration:2 vCPU 4 core per vCPUIn this scenario, your VM would have 2 sockets and 8 cores in total.How can I provision my vCPU, is there a guide or documentation regarding it?Absolutely yes, please give the following article a readCPU Configuration So is there a way to overprovision my CPU?Absolutely yes, please give the following article a readCPU Oversubscription
Nutanix REST API gives flexibility to a developer or an administrator to create scripts which can execute administrative jobs on a Nutanix cluster. Using the API, you can request information about different entities in the cluster or even change some configuration. Everyone at the end of the day wants to make sure that their infrastructure is fully secure. So what about Authentication? What kind of authentication does REST API require? Nutanix support multiple authentication options. Want to know about them and how to configure and use them in your scripts? Give the following KB a readKB-2257 Want to know more about Nutanix REST API and different dev tools we provide? Log on to https://www.nutanix.dev/ Want to know more about Nutanix REST API Explorer and play around(with caution) with the APIs in your Nutanix Cluster? REST API Explorer
Regenerating security certificates is always a good security policy and should be strictly implemented in every mission-critical production infrastructure.In the case of Nutanix guest tools, the certificates are scheduled to expire every 3 years.After the certificates are expired, you will notice the NGT link to be false and an alert to be generated saying Guest Service is not reachable.So how do we regenerate the certificates in NGT?First, we get the VM id of the affected NGT VM using the command ncli ngt list We delete the VM entity from the ngt cli and recreate using VM id Go to VM and restart the Guest Agent ServiceGo through the following KB to get the detailed information regarding the procedure and the commands involved.KB-8120
Since managing the infrastrucute is a complicated process, our customers tend to customize the AHV hosts names for identification and a general order in the cluster. Let’s say there is a situation where you want to change the hostname of your AHV host from default to something local to your organization and demands. Do we have a process or a documentation guide to help you with the task? The following knowledge base article How to rename AHV hosts will help you. The solution is also documented in our AHV Administration Guide AHV Admin guide: Changing the Acropolis Host Name
