Apple Mac Mini on VMware HCL!

08/01/2019 by William Lam 4 Comments

For the past 6 years, the Apple Mac Mini has been one of the most popular hardware platforms for Virtualizing MacOS running on VMware vSphere enabling our customers to develop and build iOS and MacOS applications. With that said, VMware has historically only supported two Apple hardware platforms: Xserve (now EOL'd) and the Mac Pro (6,1) which is officially listed on VMware's Hardware Compatibility list and this has been officially supported by VMware since 2012 when we first introduced support for MacOS Virtualization with the vSphere 5.0 release.

As many of you know, I have been a huge advocate of this platform for a number of years now and I have been working with various Engineers over the years to ensure that we have the exact same user experience when working with ESXi on the Mac Mini as you do with the Mac Pro. I still recall in the early days where it took several "hacks" to get ESXi to successfully boot and install.

Today, ESXi installs on the Mac Mini just like any other x86 platform. It runs amazing well for our customers, especially for a consumer device, who have deployed them in their datacenters ranging from a couple hundred to several thousands for some of our larger Enterprise customers, one such example is MacStadium, the largest Apple Infrastructure-as-a-service provider which many of the Fortune 100/500 companies are leveraging to provide them with a platform to build and develop for the Apple eco-system.

How to prevent physical CD-ROM from ejecting after installing or upgrading ESXi?

07/15/2019 by William Lam Leave a Comment

While catching up on some news over the weekend, I had noticed a VMware Reddit thread asking a pretty interesting question on how to prevent the physical CD-ROM tray from ejecting after installing or upgrading ESXi? This behavior occurs whether you are using a physical CD-ROM media or a "Virtual" ISO image via an out-of-band interface like an iDRAC or iLO. If you are automating the installation or upgrade using Auto Deploy or network installation such as Kickstart, this is not a problem.

However, I was a bit surprised to hear that this was still a pain point in 2019, as many of the new servers in market do not even include an option for CD-ROM. Some of the suggestions really brought me back to the early 2000's including physically taping up the CD-DROM tray, which I have definitely seen customers doing but this is not a scalable solution and it requires a visit to the datacenter.

One easy solution that I had suggested was to take advantage of ESXi's scripted installation capability also known as Kickstart and use the supported ESXi --noeject option after reboot. Since the install/upgrade was being done manually, the added benefit of this solution is that you can now have it automated 🙂 The other nice thing about this option is that you can specify the kickstart using the default ESXi ISO or you can take it a step further and embed the Kickstart with a custom ESXi ISO.

Automated ESXi Installation to USB using Kickstart

07/09/2019 by William Lam 5 Comments

I frequently re-install ESXi on my physical host for various types of testing as I normally work with a number of future releases. Although the process just takes a couple of minutes, having to enter the exact same information each time and also requiring a keyboard and monitor is not really ideal. For the majority, this is really not a problem and manually going through the install workflow is fine for most folks, especially as this is an infrequent operation.

However, with some recent customer conversations, I thought it was worth while to re-visit this topic and demonstrating just how easy it is to automate the installation of ESXi with just a single bootable USB device and embedding an ESXi Kickstart Script. Even for infrequent installation and/or upgrades of ESXi for home labs, this can be a time saver, especially if you do not have monitor and keyboard just lying around. Below are instructions including a reference Kickstart example that folks can use as a starting point. For more advanced automation, please take a look at my ESXI Kickstart Resources as well as the official VMware documentation for ESXi Scripted Installations.

Aquantia 10GbE ESXi Driver for Apple 2018 Mac Mini

04/10/2019 by William Lam 8 Comments

I know many of you have been anxiously waiting for ESXi to be fully functional on the latest Apple Mac Mini (2018), unfortunately I do not have any news to share with you on that front. Without help from Apple, we are still challenged with Apple's new T2 chip, which prevents us from accessing the underlying NVMe device.

Having said that, I do have some exciting news regarding the built-in 10Gigabit Ethernet adaptor on the 2018 Mac Mini. The 10GbE adaptor uses an Aquantia chipset, this is also the same chipset used in Apple's high end iMac Pro which was released earlier in the year. Over the past few weeks, I have been working with the Aquantia team and they have successfully ported over their open source Atlantic driver to a VMKlinux driver for ESXi, which they have published here. Although the local NVMe device can not be used to run any VMs, with the network fully enabled, customers could take advantage of this model and connect to IP-based storage to start leveraging the new Mac Mini platform.

The easiest way to incorporate the driver into the latest ESXi release is to use Image Builder within the vSphere H5 Client UI, below are the step-by-step instructions.

Revisiting prompting for user input during an interactive or scripted install of ESXi

01/10/2019 by William Lam 2 Comments

For those that have a need to prompt for additional user input during an installation of ESXi, whether that is an interactive session or using a scripted install (Kickstart) may have noticed the solution posted in my 2015 blog post no longer works with recent releases of ESXi (newer than 6.0).

I was recently contacted by VMTN community cacheman, who authored the original snippet after my 2011 post with an updated solution that would work with newer releases of ESXi (e.g. 6.5 or newer). Thanks to Chris, he discovered the following after taking another look at the initial hack:

It seems that the tty1 techsupport.sh which I had commented out in /etc/inittab is having no effect in these versions and the login prompt is starting on tty1. As far as I can tell this is because for versions >= 6.5, the init process starts before the extras.tgz is unpacked, so it reads the /etc/inittab that comes natively with ESXi rather than the modified one in extras.tgz.

Supermicro E300-9D (SYS-E300-9D-8CN8TP) is a nice ESXi & vSAN kit

11/23/2018 by William Lam 24 Comments

Supermicro kits such as the E200-8D is a very popular platform amongst the VMware community and with powerful Xeon-based CPUs and support for up to 128GB of memory, it is perfect for running a killer vSphere/vSAN setup!

Earlier this Fall, Supermicro released a "big daddy" version to the E200-8D, dubbed E300-9D and specifically, I want to focus on the 8-Core model (SYS-E300-9D-8CNTP) as this system actually listed on the VMware HCL for ESXi! The E300-9D can support up to half a terabyte of memory and with the 8-Core model, you have access to 16 threads. The E200-8D is also a supported platform by VMware, you can find the VMware HCL listing here.

I was very fortunate to get my hands on a loaner E300-9D (8-Core) unit, thanks to Eric and his team at MITXPC, a local bay area shop specializing in embedded solutions. In fact, they even provided a nice vGhetto promo discount code for my readers awhile back, so definitely check it out if you are in the market for a new lab. As an aside, when doing a quick search online, they also seem to be the only ones actually selling the E300-9D (8-Core) system which you can find here and in general, they seem to be priced fairly competitively. This is not an endorsement for MITXPC, but recommend folks to compare all prices when shopping online, especially as today is Black Friday in the US and Cyber Monday is just a few days away.
