Intel's Alder Lake-based 12th Gen "Wall Street Canyon" NUC Professional series is currently been shipped out. This article takes a deep look at their capabilities to run VMware ESXi. While VMware does not officially support NUCs, they are ubiquitous in many home labs and test environments. They are small, silent, transportable, and have very low power consumption, making them a great server for running your inexpensive home lab. The Wall Street Canyon is available with i3, i5, and i7 CPUs. The i5 and i7 versions are also available with vPro Support.
- NUC12WSHv7 / NUC12WSKv7 (Intel Core i7-1270P vPro - 4 x up to 4.80 GHz / 8 x up to 3.50 GHz)
- NUC12WSHv5 / NUC12WSKv5 (Intel Core i5-1250P vPro - 4 x up to 4.40 GHz / 8 x up to 3.30 GHz)
- NUC12WSHi7 / NUC12WSKi7 (Intel Core i7-1260P - 4 x up to 4.70 GHz / 8 x up to 3.40 GHz)
- NUC12WSHi5 / NUC12WSKi5 (Intel Core i5-1240P - 4 x up to 4.40 GHz / 8 x up to 3.30 GHz)
- NUC12WSHi3 / NUC12WSKi3 (Intel Core i3-1220P - 2 x up to 4.40 GHz / 8 x up to 3.30 GHz)
The Wall Street Canyon is Intel's professional line from their 12th NUC Generation and the successor to the 11th Gen Tiger Canyon. This system is intended for professional use cases and has significant enhancements for your homelab running ESXi. Like the previous generation, it has an expansion bay that allows you to install a second network adapter.

HCL and VMware ESXi Support
Intel NUCs are not supported by VMware and are 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.
ESXi 8.0 - ESXi runs out of the box with the original image.
ESXi 7.0 - The Community Networking Driver for ESXi is required.
Currently, there is no driver available for ESXi 6.x
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 I225-LM) - "No Network Adapters" Error with ESXi 7.0
The Community Networking Driver for ESXi is required to install ESXi 7.0 on the 12th Gen NUC. See Installation for instructions.
Storage (AHCI and NVMe)
The storage controller works out of the box with ESXi 7.0 and ESXi 8.0.
Tested ESXi Versions
- VMware ESXi 8.0
- VMware ESXi 7.0 U3 (Custom Image only)
- VMware ESXi 7.0 U2 (Custom Image only)
When you try to install ESXi 7.0 or 8.0 on a system with a 12th Gen Intel CPU, the installation fails with a purple diagnostics screen:
HW feature incompatibility detected; cannot start
Fatal CPU mismatch on feature "Hyperthreads per core"
Fatal CPU mismatch on feature "Cores per package"
Fatal CPU mismatch on feature "Cores per die"
This problem is caused by the new CPU architecture which includes different types of cores - Performance-cores and Efficient-cores. With vSphere 7.0 Update 2, the kernel parameter cpuUniformityHardCheckPanic has been implemented to address the issue. The option can be configured with the following command:
# localcli system settings kernel set -s cpuUniformityHardCheckPanic -v FALSE
An easy workaround is to temporarily disable E-cores, install ESXi, set the parameter, and re-enable E-cores. If you want to keep E-cores enabled during installation, see this article with a scripted install example.
If you want to use ESXi 8.0, just download the Image and create a bootable USB flash drive.
If you try to install ESXi 7.0, the installer fails with a "No Network Adapters" error. A driver for the Intel I225-LM 2.5GbE adapter is not bundled in the standard ESXi Image but is available as a community-based VMware Fling.

How to create a Custom ESXi Image
This option explains how to create the Custom Image with PowerCLI. The Image can be used to install ESXi from scratch.
- Download the driver Net-Community-Driver_126.96.36.199-1vmw.700.1.0.15843807_19480755.zip
- Copy the driver to your Build Directory (c:\esx) for example
- Open PowerShell
- Run the following commands in your build directory:
# (Optional) Install PowerCLI Module Install-Module -Name VMware.PowerCLI -Scope CurrentUser Add-EsxSoftwareDepot https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml Export-ESXImageProfile -ImageProfile "ESXi-7.0.0-15843807-standard" -ExportToBundle -filepath ESXi-7.0.0-15843807-standard.zip Remove-EsxSoftwareDepot https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml Add-EsxSoftwareDepot .\ESXi-7.0.0-15843807-standard.zip Add-EsxSoftwareDepot .\Net-Community-Driver_188.8.131.52-1vmw.700.1.0.15843807_19480755.zip New-EsxImageProfile -CloneProfile "ESXi-7.0.0-15843807-standard" -name "ESXi-7.0.0-15843807-NUC" -Vendor "virten.net" Add-EsxSoftwarePackage -ImageProfile "ESXi-7.0.0-15843807-NUC" -SoftwarePackage "net-community" Export-ESXImageProfile -ImageProfile "ESXi-7.0.0-15843807-NUC" -ExportToIso -filepath ESXi-7.0.0-15843807-NUC.iso
- Use the ISO image to install ESXi. The simplest way to install ESXi is by using the ISO and Rufus to create a bootable ESXi Installer USB Flash Drive. No custom BIOS Settings are required.
If you have already installed ESX (with a USB NIC for example) you can install the newer driver with the following command:
# esxcli network firewall ruleset set -e true -r httpClient # cd /tmp/ # wget https://download3.vmware.com/software/vmw-tools/community-network-driver/Net-Community-Driver_184.108.40.206-1vmw.700.1.0.15843807_19480755.zip # esxcli software vib install -d Net-Community-Driver_220.127.116.11-1vmw.700.1.0.15843807_19480755.zip
The performance of a single NUC is sufficient to run a small home lab including a vCenter Server and 3 virtual ESXi hosts. It's a great system to take along for demonstration purposes. If you have multiple systems and a vCenter Server you can build a powerful cluster.
The following chart is a comparison based on the NUCs PassMark score. The performance gap to previous generations is huge, which is a result of going up from 4 to 16 Cores.
NUCs have a very low power consumption. I've measured the power consumption of a NUC12WSHv5 in 3 states: Idle (ESXi in Maintenance Mode), Average Load (1 vCenter, 4 Linux VMs), and during a Stress test. The NUC has been configured with 64GB RAM and no HDD or SSD. The power policy was configured to be "Balanced".
- Idle: 16 W
- Average Load: 24 W
- Stress Test: 65 W
The average operating costs are a little over 5 Euros per month:
17 watt * 24 h * 30 (days) = 17,28 KWh * 0,30 (EUR) = 5,18EUR
Consumption measured with Homematic HM-ES-PMSw1
