ESXi with Intel Arc 750 / 770 GPU

by // 21 Comments

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?

by // 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.

Nested ESXi installation using HTTPS boot over VirtualEFI in vSphere 8

by // 2 Comments

In vSphere 7.0 Update 2, an enhancement was made to the Virtual Machine's UEFI firmware called VirtualEFI that would enable ESXi to run in a VM (Nested ESXi) and perform an HTTP Boot given the ESXi bootloader URL without requiring any traditional PXE infrastructure.

This was especially useful for anyone testing or developing ESXi automation for use with ESXi Kickstart, where you can quickly prototype your automation without additional infrastructure dependencies and once the automation has been vetted, you can then leverage that exact same automation in your physical ESXi provisioning infrastructure.

The original solution had only supported HTTP and I recently came to learn that we can now also support HTTPS in vSphere 8!
