ESXi on Arm Fling is LIVE!

by // 17 Comments


The highly anticipated ESXi on Arm Fling has just been announced and is NOW generally available as a new VMware Fling! Head over to https://community.broadcom.com/flings and be sure to carefully read through the documentation before try out the bits.

History

Although ESXi-Arm was publicly demo'ed at VMworld Europe 2018 during the closing keynote by Ray O'Farrell (former CTO of VMware), the reality was there was a ton more to do before ESXi-Arm could be a reality for VMware customers. The newly formed ESXi-Arm team at VMware has been hard at work these last couple of years working with both Arm and its eco-system in extending hardware standards, firmware standards (open contribution to UEFI), and certification beyond the existing Arm server ecosystem, which enabled us to support platforms like SmartNICs and the ubiquitous Raspberry Pi. This is just a glimpse into what it took to get where we are at today.

I am also excited to share that the Virtually Speaking Podcast crew has invited us back for an exclusive episode featuring both Andrei Warkentin and myself to dive deeper into the development of ESXi-Arm project at VMware. This is an episode you will not want to miss!

Hardware

The ESXi-Arm Fling supports a number of different Arm platforms ranging from a traditional Datacenter form-factor to both Near and Far Edge systems including the highly requested Raspberry Pi (rPI)! With the rPI, only the 4b model will be supported and although both the 4GB and 8GB memory model works with ESXi-Arm. We highly recommend folks invest in the 8GB model to be able to take advantage of more vSphere features and be able to run more workloads.


For a complete list of supported Arm hardware platforms, please refer to the ESXi-Arm documentation.

vCenter Support

For customers with an existing x86 vCenter Server or those that would like to deploy a new vCenter Server, you will be able to attach and manage ESXi-Arm hosts just like you normally would as long as you are using vCenter Server 7.0 or greater.


We expect the majority of vSphere platform features to "just work" like vMotion but there may be some features that may not work or have additional requirements.


For example, to enable vSphere HA and/or vSphere FT, the Fault Domain Manager (FDM) Client VIB must be installed on an ESXi-Arm host. Today, this VIB is distributed as part of vCenter Server and only x86 version of the client is available. We do provide FDM Client VIBs for ESXi-Arm as part of the ESXi-Arm Fling, but support will be limited to vCenter Server 7.0c and 7.0d. For detailed instructions, please refer to the ESXi-Arm documentation.

VMware Tools

VMware Tools for ESXi-Arm GuestOS is not bundled as part of ESXi-Arm Fling, but can be installed. To do so, you will need to compile open-vm-tools for your respective GuestOS. Instructions can be found in the ESXi-Arm Fling documentation and below, you can see a screenshot of VMware Tools for Arm successfully running on Ubuntu 20.04 GuestOS running on ESXi-Arm on the rPI 4.

vSAN Witness

Lastly, a popular use case that has been brought up when ESXi-Arm was initially demo'ed was the use of the rPI as an inexpensive vSAN Witness, which is a fantastic use case for ROBO & Edge locations. I am very happy to share that using an rPI 8GB as a vSAN Witness works! As you can see from the screenshot below, I have two physical Intel NUC 9th Pro configured in a 2-Node vSAN Cluster and I am using the rPI as vSAN Witness 😀


In case this was not clear, this is NOT officially supported but it does demonstrate the viability of this concept and and feedback from the our users would help drive the priority and the potential support for such a configuration. More details will be shared in a future blog post outlining the instructions on using rPI as vSAN Witness. Stay tuned!

As you can see, this is just a small taste of what can be done with the ESXi-Arm Fling and the possibilities are truly endless! The ESXi-Arm team is very excited to see what the community will do with the ESXi-Arm Fling, what type of use cases are you solving or workloads that you are running. Below are a few ways in how you can engage with the ESXi-Arm team and community.

Two methods to network boot Raspberry Pi 4

by // 27 Comments

My Raspberry Pi 4 (8GB) model just came last week and after completing my RADIO (VMware's R&D Innovation Offsite) session recording, I wanted to setup my new rPI so I can start playing with it when I had some spare time. I also have the 4GB model but it was running quite hot as I was using the default case (do not recommend) and decided to put that aside for now. I ended up purchasing the 8GB model from Canakit which includes additional heatsinks and nice built-in fan with their custom case.

After spending some time setting up the rPI OS and applying the various updates, I was not too keen on using the SD Card, especially as some folks on forums mentioned that it can easily be worn out depending on the type of workload. While researching online and some references pointed out by colleagues, I came to learn that in addition to booting from USB which is now possible with rPI, you can also network boot the rPI without an SD Card or any storage for that matter! This immediately resonated with me, especially as I am a huge fan of scripted installations such as Kickstart/Jumpstart.

Here are all the resources that I had used that provided all the heavy lifting. I have optimized some of the commands to make it easy for anyone to simply copy and past who is new to setting up an rPI. The authors below did a fantastic job in outlining all the details, so I highly recommend a read if you would like to get more information. I also will be going over an alternative method at the end for booting the rPI over the network which is not really talked about.

One really cool thing that I came to learn while setting up the infrastructure to network boot an rPI was the use of dnsmasq, which I have used in the past but I did not realize it could do so much more. I may have spent more time playing with dnsmasq than with the rPI itself and I will probably cover this in another blog post on how you can easily setup a PXE/gPXE/iPXE system to enable automated OS installation (e.g. Kickstart) that can be used with ESXi or any other OS for that support network installations via BIOS/UEFI.

Touch screen + case for the Raspberry Pi 3

by // 3 Comments

I just purchased a nice little touch screen for my Raspberry Pi 3 (rPI) which I had shared on Twitter yesterday and a number of folks were also interested in the details. First off, I want to give a huge shoutout to Frances Wong who I came to learn about this nifty touch screen in the first place. I noticed that Francis only had the screen adaptor and I was also interested in getting a case that can house both the rPI and the touch screen. After a quick search online, I found there was a companion case which I had also purchased and you can see what it looks like fully assembled below.
