Removable M.2 NVMe SSD PCIe enclosure by Icy Dock

07.27.2020 by William Lam // 6 Comments

My homelab is a constant experiment and hardware components are moved around for various testing, especially when it comes to networking and storage. When needing to move around an M.2 NVMe SSD, complexity of taking apart a system will vary on the platform but generally it is inconvenience. When I came to learn that Icy Dock, a manufacturer of storage enclosures, will be releasing a removable M.2 NVMe SSD tray that is connected to PCIe expansion slot, I knew I had to get my hands on it.


The good folks over at Icy Dock were kind enough to send me an early evaluational unit of the upcoming MB840M2P-B which is now available for $69. will be released in August and should retail for around $80 USD (final prices are still TBD). The use case above may not apply to most folks and is probably unique to my specific hardware usage but I think this is still a very interesting solution that is still useful to be aware of if you are your own homelab whitebox and have a spare PCIe slot. Icy Dock also produces many other types of storage enclosures that you might find interesting based your own needs.

For my setup, I installed the MB840M2P-B into my Intel NUC 9 Pro, which is definitely not easy to take apart. This is especially true for the two M.2 which is attached to the NUC Element but even more painful to get to the 3rd M.2 which is located under the baseboard. For my specific use case, this was well worth using up one of the PCIe slots on the NUC 9 Pro! This enclosure can also be added to the new 2019 Mac Pro which is another platform that Icy Dock sees benefiting from this solution.

Passthrough of Integrated GPU (iGPU) for Apple Mac Mini 2018

06.25.2020 by William Lam // 39 Comments

After successfully enabling and persisting the passthrough of the iGPU for the latest Intel NUC 10 (Frost Canyon), I thought it was worth experimenting with the Apple Mac Mini 2018 to see if the same could be accomplished with its iGPU, which is an Intel UHD 630. The biggest benefit in addition to unlocking the iGPU for general use is support for Apple's Metal API which gives developers access to the underlying GPU when building and testing MacOS and iOS applications. This is also quite timely as the Apple Mac Mini 2018 was just added to the VMware HCL!

My initial attempt failed when using the latest ESXi 6.7 Update 3 release. After enabling passthrough of the iGPU and rebooting the ESXi host for the change to take affect, the system would get stuck during boot up when loading the dma_iommu_mapper module. After speaking with Engineering, the issue is probably not related to dma_iommu_mapper module but some other module shortly after but without serial console output or ability to see terminal screen, it would be very difficult to debug the issue.

About to give up, my last attempt was try ESXi 7.0 and to my surprise the ESXi host fully booted up after enabling passthrough of the iGPU. It is still not clear on what might be causing the problem for 6.7 but at least 7.0 works!

Note: To be able to successfully power on a MacOS VM running on ESXi 7.0, ensure you have applied the recent ESXi 7.0b patch. You will need to go to the VMware Patch Portal siteto download and apply the update.

Step 1- Enable passthrough of the iGPU using the vSphere UI and then reboot for changes to take affect.

Step 2 - Navigate to Configure->Hardware->Graphics->Host Graphics and change the default graphics type to "Shared Direct"

Quick Tip - HTTPs now supported with wget on ESXi 7.0

06.18.2020 by William Lam // 4 Comments

This morning I needed to install the USB Network Native Driver Fling for ESXi and realized that offline bundles can not be installer over a remote URL. I figure I would download it directly to my ESXi host using wget. As soon as I hit the enter key to send the command I quickly remember that this will fail as the version of wget in the ESXi Shell does not support HTTPs. To my surprise, it actually worked! 😍

[root@nuc:~] wget https://download3.vmware.com/software/vmw-tools/USBNND/ESXi700-VMKUSB-NIC-FLING-34491022-component-15873236.zip

ESXi700-VMKUSB-NIC-F 100% |**************************************************************************************************************************************************************************| 341k 0:00:00 ETA

This looks to be an enhancement in ESXI 7.0 and you no longer will get the "bad address" error when specifying an HTTPs URL as shown in the example below when running against the latest ESXi 6.7 Update 3 release.

[root@esxi67:~] wget https://download3.vmware.com/software/vmw-tools/USBNND/ESXi700-VMKUSB-NIC-FLING-34491022-component-15873236.zip
wget: bad address 'download3.vmware.com'

Thank you to the Engineer who fixed this, this was a very pleasant and welcome surprise that I know will also be helpful to folks who automate using ESXi Scripted Installations.
