First look at Proxmox Datacenter Manager (PDM) – managing multiple Proxmox clusters from a single pane of glass

Did you hear about Proxmox Datacenter Manager? – The new project aims to offer a centralized overview and basic management of multiple nodes and clusters.

It was a most anticipated solution for many Proxmox users, and I believe it has a great future. For now, Proxmox Datacenter Manager is in the alpha phase, and I do not recommend using it in a production environment, but the stable version is planned for 2025, so stay tuned! You can check the project roadmap here.

Next, we will look at how to deploy Proxmox Datacenter Manager and how to connect our first cluster.

What’s new at Nutanix University? New certification NCP-CN and beta exams opportunities

Nutanix released a new anticipated training and certification related to the Nutanix Kubernetes Platform, or NKP.

First, the new course, Nutanix Kubernetes Platform Administration (NKPA), is available for free online at Nutanix University! The course is based on AOS 6.10, Prism Central 2024.2, and Nutanix Kubernetes Platform 2.12, and teaches you how to deploy, configure, and manage the Nutanix Kubernetes Platform (NKP).

New certification Nutanix Certified Professional – Cloud Native (NCP-CN) developed to test your abilities in deploying, managing, and troubleshooting NKP.

For now, the certification is in a beta state and available totally free for the first 250 participants, just use the discount during checkout: NCPCN610BETA. You can find this certification on the PSI certs lists. The first test date is January 28, 2025, and you have time to prepare. The last test date is March 10, 2025.

Keep in mind, that during the beta state, you won’t get your results immediately after completing the exam. Usually, it takes a month or two after beta is over, and I can guess that the results of the exam could be at the end of April or in May.

Preparing for the Nutanix Certified Professional – Multicloud Infrastructure 6.10 (NCP-MCI 6.10) Exam

I see that many people are interested in taking the Nutanix Certified Professional – Multicloud Infrastructure 6.10 exam, so I decided to revamp my previous guide based on version 6.5.

This guide describes the methodology I am using in preparing for certification exams, and it could be used for other Nutanix exams as well.

Nutanix Certified Professional is the second stage in the Nutanix certification track. This certification requires the candidate to have good theoretical and practical knowledge of working with Nutanix solutions and is divided into several tracks:
Nutanix Certified Professional – Multicloud Infrastructure (NCP-MCI)
Nutanix Certified Professional – Database Automation (NCP-DB)

Nutanix Certified Professional – Multicloud Automation (NCP-MCA)
Nutanix Certified Professional – End User Computing (NCP-EUC)
Nutanix Certified Professional – Cloud Integration (NCP-CI)

In this article, we will look at the main topics from the Nutanix Certified Professional – Multicloud Infrastructure (NCP-MCI) exam version 6.10, and I will also share materials, that you can use to prepare yourself.

Preparing for the Nutanix Certified Associate 6.10 (NCA 6.10) Exam

I see that many people are interested in taking the Nutanix Certified Associate 6.10 exam, so I decided to revamp my previous guide based on version 6.5.

This guide describes the methodology I am using in preparing for certification exams, and it could be used for other Nutanix exams as well.

Nutanix Certified Associate is the first step in the Nutanix certification track. This is an entry-level exam that tests knowledge of general Nutanix theory, basic cluster management skills, and an understanding of the Prism interface.

Below, I will share my experience of passing the Nutanix Certified Associate exam version 6.10 and also leave some tips for self-preparation.

Using Veeam Hardened Repository ISO and creating Hardened Repository

Did you know about Veeam Managed Hardened Repository ISO? This is a Rocky-based Linux distro, which is already pre-hardened to comply with DISA STIG requirements. In addition, Veeam Hardened Repository ISO provides simplified installation and management; there is a text-based user interface that includes all the basic features needed to configure OS and use it as a Veeam Repository.

You can get more information about features, requirements, and limitations on the Veeam R&D Forum.

With the build 0.1.17, this ISO left the technical preview state and got the production-ready status, including Veeam Experimental Support, so you can consider putting it to use.

In this article we will look at how to deploy a server, using Veeam Hardened Repository ISO and how to create a hardened repository using this server.
