Intel's Coffee Lake-based 8th Gen Bean Canyon NUC is an ideal candidate for running VMware ESXi. NUCs are not officially supported by VMware but they are very widespread in many homelabs or test environments. They are small, silent, transportable and have very low power consumption, making it a great server for your homelab. The Bean Canyon is available with i3, i5, and i7 CPU. It's the first series where the i5 is also equipped with a Quad-Core CPU, so both - the i5 and i7 - are ideal candidates for ESXi.

HCL and VMware ESXi Support
Intel NUCs are not supported by VMware and not listed in the HCL. Not supported means that you can't open Service Requests with VMware when you have a problem. It does not state that it won't work. Some components used in the NUC are listed in the IO Devices HCL.
ESXi runs out of the box starting with the following releases:
- ESXi 6.5 Update 2 (Build 8294253) released in May 2018
- ESXi 6.7 Update 1 (Build 10302608) released in October 2018
To clarify, the system is not supported by VMware, so do not use this system in a productive environment. I can not guarantee that it will work stable. As a home lab or a small home server, it should be fine.
Network (Intel I219-V) - "No Network Adapters" Error
The network adapter does not work out of the box with ESXi versions prior to 6.7u1 or 6.5u2. If you need older ESXi versions to work you have to inject the ne1000 driver manually to the installer image (ESXi 6.5: 0.8.3-7vmw.6184.108.40.20694253 / ESXi 6.7: 0.8.4-1vmw.6220.127.116.1102608).
8th Gen NUCs are equipped with a Micro SDXC Slot. Unfortunately, there is no driver available for ESXi at the moment so it's not possible to use the SD Card slot.
Tested ESXi Versions
- VMware ESXi 6.5 U2
- VMware ESXi 6.5 U3
- VMware ESXi 6.7 U1
- VMware ESXi 6.7 U2
- VMware ESXi 6.7 U3
Delivery and assembly
The Box contains a short description of how to open and assemble the components. The system is a little bit heavier than it looks and has a high build quality. The upside is very scratch-sensitive, so be careful with it.
The installation is very simple. Remove 4 screws on the bottom and remove the lid and the 2.5" drive holder. The assembly takes about 5 minutes to open the NUC, install memory, NVMe SSD module and a 2.5" drive.
No customization is required to install ESXi 6.5U2 / ESXi 6.7U1 or later on the 8th Gen Bean Canyon NUC. I recommend to use the latest image provided by VMware to Install ESXi:
- VMware vSphere Hypervisor (ESXi) 6.7U3 [Release Notes] [Download]
- VMware vSphere Hypervisor (ESXi) 6.5U3 [Release Notes] [Download]
There is a problem with the ESXi installer when UEFI boot is enabled. To work around the issue, configure the NUC to boot in legacy mode. This step is required for the installation only and can be changed back after.
- Power on the NUC
- Press F2 to enter BIOS
- Disable Secure Boot (Advanced -> Boot -> Secure Boot)
- Enable Legacy Boot (Boot Order > Legacy > Legacy Boot)
- Press F10 to save and exit
Now you should be able to proceed with the ESXi installation. The installer might seem to be stuck for about 2 minutes at "nfs4client failed to load", just be patient. When the installation is finished you can disable Legacy Boot.
Warning: If you've installed ESXi to an NVMe drive, you have to disable Legacy boot as NVMe can only boot with UEFI.
The performance of a single NUC is sufficient to run a small home lab including a vCenter Server and 3 ESXi hosts. It's a great system to take along for demonstration purposes. The i7 is even faster than the Hades Canyon and the i5 is, thanks to its quad-core CPU, on a par.
The following chart is a comparison based on the NUCs PassMark score:
NUCs have very low power consumption. The NUC8i7BEH with an M.2 NVMe draws about 25W. With that, the average operating costs are at about 5-6 Euros per month:
25 watt * 24 h * 30 (days) = 18 KWh * 0,30 (EUR) = 5,40 EUR
