ESXi on ARM VMware Sub Community

Took me a little while to find (as it is not listed in the main list of communities) but there is an ESXi on ARM VMware sub community and it can be found here...https://communities.vmware.com/community/vmtn/vsphere/esxi/esxi-arm-fling

New Professional vSphere 7.x Exam Released

Image
There's been some big news this week about VMware certification involving the release of the new Professional VMware vSphere 7.x exam. So, what does this mean and how does it affect someone wishing to become VCP certified? As there are a number of technology areas you can achieve a VCP certification in, this post is going to look at the 'VCP - Data Center Virtualisation' track.
https://www.vmware.com/education-services/certification/vcp-dcv-7-exam.html
To start with, back in Feb 2019 VMware changed the naming of the VCP certification to now include the year you passed the exam rather than specifying the version of vSphere that you had studied and were examined on. So last year we had the VCP-DCV 2019 and this year will be the VCP-DCV 2020.
If you are already a VCP 2020 then passing this new exam won't gain you anything extra. If, however if you do not currently have a VCP then VMware have dropped the requirement that meant you had to take and pass the Foundations exam.

Here is a great little video from VMware explaining the basics of Kubernetes. As learning about cloud native applications looks to become increasingly important, then any extra help understanding and remembering all the new terms is always helpful. 

Requirements to become a VCP-DCV 2020

Image
Want to become VMware VCP - DCV certified but not sure of the requirements?
This is a question I am asked a lot on the Install Configure Manage course I teach so I thought I'd explain what the requirements and the steps are.
There are several levels of certification from VMware, VCA, VCP, VCAP and VCDX and there are different certification tracks that you can study - Data Center, Network, Cloud Management & Automation and Desktop & Mobility. In this post, I am going write about the VMware Certified Professional - Data Center Virtualisation or VCP-DCV as it's written in short.
The first thing that we need to know is that the certification you gain now carries the year you became certified rather than the product version, so if you fulfilled the requirements to be a VCP-DCV this year, you would become a VCP-DCV 2020.
The steps to become a VCP-DCV 2020 are listed in the Certification section under Education Services on VMware's website...

macOS 11 beta in a VM

Image
I've been having some fun getting macOS11 (also referred to as macOS 10.16 during install) Big Sur beta 1 running in a VM within VMware Fusion. If you've not met Fusion before, it's VMware's hypervisor for the Apple Mac. It's a really useful tool for a lot of people right now as Apple has given developers access to the first beta code this week and Fusion allows us to test the new release running in a VM.
As usual, running unsupported, pre release software sometimes brings up challenges...
Downloaded the macOS 11 beta installer from Apple. It's about 10GB so may take a little while. Then I obtained a USB stick (16GB minimum) and formatted it with Disk Utility leaving the default name of Untitled. Then, using Terminal, I ran the following command to create the installer and make the media bootable...
sudo /Applications/Install\ macOS\ 10.15\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applic…

These are 2 of the best books I recommend to my students in the courses I teach...

vSphere Host Resources Deep Dive (6.5) By Frank Denneman and Niels Hagoort,
If you want to have a really deep understanding about how an ESXi host handles resource management then this is the book for you. It also goes into a lot of depth about processor architecture and topics such as vNUMA. Even though it is based on ESXi 6.5, there is still a ton on incredibly useful information within.

vSphere Clustering Deep Dive (6.7) By Duncan Epping, Frank Denneman and Niels Hagoort.
This book goes really deep into how vSphere HA works and how to create a robust HA cluster along with explaining how to get the best out of DRS, network resource pools and resources allocation settings. There is never enough time to go through all the minute detail in class but you'll find it here in this book. Download this bo…
