Replacing the Nutanix Witness VM on an existing Metro Availability Protection Domain — Multi-Cloud Life

Last week, I had to change an existing Metro Availability Protection Domain between 2 Nutanix Sites. The change was to replace the existing Witness VM with a new one to be deployed on another VMware ESXi host. 33 more words

Scaling Storage Capacity – Nutanix vs VMware vSAN – CloudXC

No alternative text description for this image

 

In the first post in this series I compared the actual Usable Capacity between Nutanix ADSF vs VMware vSAN on the same hardware.

We saw approximately 30-40% more usable capacity delivered by Nutanix.

Next we compared Deduplication & Compression technologies where we learned Nutanix has outright capacity efficiency, flexibility, resiliency and performance advantages over vSAN.

Then we looked at Erasure Coding where we learned the Nutanix implementation (called EC-X) is both dynamic & flexible by balancing performance and capacity efficiencies in real time.

vSAN on the other hand has a rudimentary “All or nothing” approach which can lead to higher front end impact and does not dynamically apply Erasure Coding to the most suitable data.

Customizing AHV VMs with RestAPI – Nutanix.dev

CUSTOMIZING AHV VMS

This article provides an introduction to the nature of Guest Customization support for AHV VMs and how one can configure this using the Prism Central v3 APIs.

Overview

Using the AHV Image Services and Clone functionality, users can reduce the amount of time needed to bring up an AHV Virtual Machine (VM). As per their organisational security standards, users can have base images with the necessary software and patches installed in the Guest OS. However, in certain deployments, there is a need to make changes specific to a particular instance. This can be achieved via the Guest Customization functionality which allows users to have OS customization while creating a VM from AHV Image or Cloning an existing VM. The mechanism to customize a guest depends on the Guest OS; Cloud Init is used for customizing Linux Guests and SysPrep is used for Windows Guests.

In order to customize guests via v3 API, one has to make a POST request to the vms endpoint. Please refer to the vms POST documentation for how the complete VM spec has to be populated for creating a VM. Let’s look at examples around how the spec has to be populated when customizing guests.
