ESXi on ARM – Andy’s BOM !

Saturday, October 24th, 2020

If you’ve been living under a rock you may not know that a recent VMware Fling was released of ESXi on ARM. You can check out my articles on Experts Exchange and

This is my 4 (four) Raspberry Pi 4B Cluster of VMware vSphere ESXi 7.0 for ARM.

vSphere Cluster

vSphere Cluster

It’s based on 4 x Raspberry Pi 4B, Cluster/Rack, PoE and 4 x SanDisk 16GB MicroSD cards.


I did originally purchase a “Cluster” power supply at 2.4A per port, you’ll not need anymore unless you have external devices connected to your Pi, and then you may need 3A per port! switched to PoE!


So the BOM (bill of materials is as follows)

  1.  4 x Raspberry Pi 4B 8GB version from CPC (cheapest supplier in the UK, if they have stock)
  2. 1 x Pi Rack Case for Raspberry Pi 4 from Amazon
  3. 4 x PoE HAT from Amazon
  4. Sandisk MicroSD 3 Pack from Amazon 
  5. 5 Port LCD Charger from Amazon
  6. 5 Short braided USB cables from Amazon
  7. Handy USB HDMI device (connect to PI, and have PC display!)
  8. Hex drivers (if you have fat fingers like me, 5mm nuts can be fiddley!)

VMware vSphere Hypervisor ESXi 6.5a on a HP/HPE DL380 G5 – IT WORKS!

Thursday, February 16th, 2017
Sad looking DL380G5

Sad looking DL380G5

Yes, we all know that the HP/HPE DL380 G5 is not on the VMware Hardware Compatibility list, the last ESXi supported operating system was either 4.1 – 5.0, depending upon your Xeon version. But these make ideal lab servers, and one very important function is if you remove the spinning rust disk drives from the disk carriers, you can swap them directly for consumer SSDs. So this makes an ideal test vSAN. 8 SSDs, and if you happen to have enough DL380G5, and we do…. you can build a larger cluster!

VMware vSphere ESXi 6.0 does install and run on the DL380 G5, see here – INSTALL ESXI 6.0 ON A DL380 G5 – YES IT WORKS, but for shits and giggles, I want the latest and greatest 6.5!

and if you try to install ESXi 6.5 on a HP/HPE DL380 G5 with a Xeon 51xx series you will get the following error message



from the VMware vSphere ESXi 6.5 release notes

CPUs removed...

CPUs removed...

You will see the Xeon 51xx series has been removed from the code, and I also believe that more Xeon series will be removed with the next version 7.0 of ESXi, including all 52xx, 53xx and 54xx.

So I just happen to have some Xeon 5430, on my desk as coasters!

Not a matched pair of Xeon 5430

Not a matched pair of Xeon 5430

This pair are not matched…. I don’t think the world is going to come to and end…so, swap them and all will be fine…and the DL380G5 makes this simple, unlock the heat sink bar, unclip the processor clips, remove and replace…




So here you go, ESXi 6.5a on HP/HPE DL380 G5 -” IT WORKS!”

A quick tip, download the last firmware disk from HPE Firmware 10.10, and update your DL 380G5 before you swap the processors! In fact I found this server, had never had any firmware upgrades still on stock firmware!

RARE – Intel Xeon E3-1220LV2 Processor for my HP ProLiant MicroServer Gen8

Tuesday, April 12th, 2016

Here is the replacement processor for my HP ProLiant MicroServer Gen8. It has taken me a while to track this one down. It has a TDP of only 17 watts, compared to the stock Intel Celeron G1610T, which has a TDP of 35 watts.

These are like rocking horse dodo…

It’s an Intel Xeon E3-1220L V2, it’s a low power, 17 watt, 2 Core, 4 Thread Xeon with Intel VT-d.

I’m waiting for my thermal compound, before I install it.

Synology NAS and SSD Cache Part III – Is cache better for VMware vSphere (ESXi)? Confusing results!

Monday, April 11th, 2016

So in today’s, crude and experimental research I thought I would connect all our VMware vSphere Hypervisors (ESXi 5.5 build 1892794) to a NFS datastore presented to the ESXi Hosts from a Synology NAS, and we’ll try the following tests

I deployed a small Windows 7 template, onto the NFS datastore as follows

  • No Cache Enabled – 3 minutes 27 seconds to deploy
  • Read and Write Cache Enabled – 2 minutes and 40 seconds to deploy.

Time for some more testing – The template deployed to the datastore was converted to a virtual machine, and the following tests were performed using CrystalDiskMark 5.1.2 in the virtual machine.

NFS Exported volume No SSD Cache on the Synology NAS.

NFS Exported volume Read and Write SSD Cache on the Synology NAS.

NFS Exported volume Read only SSD Cache on the Synology NAS.

Some a bunch of very confusing results! And every time I test the results are similar.
