vSphere Pods using VDS based Supervisor in vSphere with Tanzu?

by // 12 Comments

vSphere with Tanzu has received an exciting update with the release of vSphere 8.0 Update 1, which removes the restriction for requiring NSX-based networking to deploy Supervisor Services. This is really cool because customers with only a VDS based Supervisor can now also get the benefits of the various Supervisor Services that vSphere with Tanzu supports!


For those not aware, Supervisor Services are deployed as vSphere Pods, which is a super tiny VM that boots up a Photon OS kernel and is configured with just enough resources to run one or more Linux containers. In earlier releases of vSphere with Tanzu, vSphere Pods required an NSX based Supervisor, but with this restriction removed in vSphere 8.0 Update 1, it seems like deploying vSphere Pods should also be possible with just a VDS based Supervisor? 🤔

96GB SODIMM memory for DDR5 system with ESXi

by // 26 Comments

Back in February of this year, I had shared that non-binary 24GB and 48GB SODIMM memory was finally available, but I quickly realized that the news from Samsung was only for traditional memory modules and not the laptop SODIMM memory, which is also commonly used in small form factor systems like an Intel NUC.

Three months later, we still have no word from either Samsung or Crucial, but recently Mushkin came out of no where and released their 48GB DDR5 SODIMM modules which I had also shared the news on my blog HERE. While DDR5 adoption is slowly increasing, there are not many systems out there right now that currently supports DDR5 and you will need a DDR5 capable system to use DDR5 memory.


I recently got my hands on a new DDR5 system, which I will share more details in a future blog post, but the maximum supported memory listed for the system is still 64GB. I was curious on whether these new 48GB SODIMM would actually work with this system? If we go back to 2019, when 32GB SODIMM was first released, it was not clear whether these would work with systems that listed 32GB as their maximum supported memory?

I was the first to confirm 32GB modules worked with the popular Intel NUCs back in 2019 and that I could even use these new SODIMM modules going all the way back to an Intel 6th Gen NUC, which was released back in 2016! So while the officially tested memory limit was only 32GB, the CPU actually supported more than that!

🙏🤞I decided to take another chance and I purchased the Mushkin 96GB DDR5 SODIMM 4800mhz kit which has just arrived and I have put my theory to the test again ...

How to enable passthrough for USB Network Adapters claimed by ESXi CDCE Driver?

by // 8 Comments

As part of vSphere 7.0, ESXi now ships with a USB CDCE (Communication Device Class Ethernet) driver which can benefit customers with SB network adapters that support the CDCE specification as shared in this blog post HERE. This can especially be useful for those running a VMware Homelab where the onboard network adapter may not be supported and using a CDCE USB network adapter would allow you to install ESXi.

When a CDCE-supported USB network adapter is connected to an ESXi host, it will automatically be claimed by the CDCE driver as shown in the screenshot below.


If you are planning to use the USB network adapter for VMkernel traffic, then there is no workflow change like any other physical network adapter. However, if you intend to passthrough the USB network adapter to a VM, then you may find that it is not working as expected.


The reason for this is that ESXi has already claimed the USB device, assuming you wish to use it for VMkernel traffic. To change the behavior for a particular CDCE-supported USB network adapter, we just need to apply a USB Quirk which tells ESXi to ignore this adapter.
