Automated ESXi Installation with a USB Network Adapter using Kickstart

02.01.2023 by William Lam // 4 Comments

I have been working with the Project Keswick team for quite some time now, which is an OCTO project is lead by my good friend Alan Renouf, who is doing some really innovative work with ESXi at the edge and application deployment using a desired state engine.

Recently I had met with the team to discuss some of the options for their automated deployment which uses the tried and true ESXi scripted installation aka ESXi Kickstart. One thing that I had shared was just how powerful the %pre section within the kickstart is and can be used to redefine or update the original kickstart based on your installation criteria. For example, you could pull down external configuration files and determine at runtime to decide how you want to configure your networking to even fully bootstrapping a local vSAN datastore and this would all happen prior to ESXi installer starting. I have used the %pre section numerous times as a customer and also demonstrated in my USB-to-SDDC project which has also been an inspiration for the Project Keswick team.

One very cool capability that Project Keswick is enabling is the integration of the popular USB Network Native Driver for ESXi and one challenge they had faced with automating an ESXi installation when only a USB network adapter was available is additional configuration that must be setup before the installer can begin. They shared their solution and thought this would be a good blog post topic, especially as I know many folks use the USB Network Native Driver for ESXi in their homelab and if you wish to automate the installation, the solution shared from the team could help.

ESXi with Intel Arc 750 / 770 GPU

01.24.2023 by William Lam // 22 Comments

I have to say, the @IntelGraphics team does a very nice job on their packaging!

Look forward to kicking the tires on their new Arc GPUs, luckily this fits nicely in the Intel 12 Extreme NUC (Dragon Canyon) 😁 pic.twitter.com/DHTC93pzmc

I recently had the opportunity to play with one of Intel's Arc 7 series discrete GPU (A750), which is part of the new Intel Arc desktop graphics product line, that was just released last Fall. While the primary audience for the Intel Arc graphics is for creators and desktop gaming, I was really interested in its applicability for a vSphere-based environment which also has a number of interesting use cases for graphics from Virtual Desktop Infrastructure (VDI), video transcoding/rendering, AI/ML, Kubernetes, general purpose graphics acceleration and even basic gaming to name a few.

While there are many GPU options in the market for vSphere, depending on your needs and budget, the new Intel's new Arc 7 series could be a nice modern option as it is touted to be both price and performance competitive with other offerings within the market.

How to bootstrap vSAN Express Storage Architecture (ESA) on unsupported hardware?

01.19.2023 by William Lam // 2 Comments

I was recently chatting with a fellow colleague who asked an interesting question about the memory overhead between running vSAN Original Storage Architecture (OSA) versus the new vSAN Express Storage Architecture (ESA) from a VMware Homelab perspective. I honestly did not know the answer as I am only using vSAN OSA for my personal homelab. I was curious myself, especially its implicationn on small form factor (SFF) systems which typically max at out 64GB of memory.

Today, vSAN ESA is only officially supported when using vSAN ESA Ready Nodes which are all listed in the vSAN ESA HCL and the minimum amount of memory is 512GB. For the best possible experience and supported configurations, customers should only use approved vSAN ESA hardware and the use of any other systems will not yield the same benefits nor outcomes. As an aside, a fantastic resource for all things vSAN ESA can be found on the vSAN ESA TechZone page, which I highly recommend bookmarking as there is a lot of in-depth technical resources and collateral.
