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...
One of the most impressive bits of technology that was announced at VMworld last year was the Bitfusion Tech Preview. It seems that AI and ML (Artificial Intelligence and Machine Learning) are being talked about more and more these days and along with these new technologies comes new challenges. New GPUs needed to run these new workloads are required but they are not particularly cheap especially when installed in all the hosts where you want your workloads to run. So essentially, Bitfusion allows GPUs on dedicated hosts to be dynamically assigned to VMs / Containers as and when needed and then removed after they are no longer required. This reminds me so much of how virtualisation solved the problem of inefficient hardware utilisation when ESX was introduced all those years ago. Anyway here is a really great explanation about what the problem is and how Bitfusion will solve it here... ...
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. Download this book here... https://www.rubrik.com/en/lp/white-papers/19/host-resources-deep-dive-ebook.html 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 boo...
