VMware Cloud Foundation (VCF) using USB Network Adaptor

by // 5 Comments

To deploy VMware Cloud Foundation (VCF), your physical or virtual ESXi host must have at least two network adaptors to be able to migrate to Distributed Virtual Switch (VDS), which is configured as part of the VCF Bringup process. While you can technically migrate to a VDS with just a single network adaptor using this trick, it is definitely easier if you have a system that meets this basic requirement.

Earlier this year, I demonstrated that you can deploy VCF using just an Intel NUC with only 64GB of memory, which would be the minimum to run single node VCF Management Domain, however it does not leave you with much room for running other workloads due to pushing the memory limits.

The ASUS PN64-E1 is currently one of my top favorite small form factor kits, especially being able to support up 96GB of memory using the new non-binary DDR5 memory modules. After the release of VCF 5.1, I wanted to use the ASUS PN64-E1 for a VCF deployment, but there was only one problem ... my particular configuration of the PN64-E1 only had a single network adaptor!

I thought I could out smart the VCF Bringup pre-check by using a USB network adaptor and installing the popular USB Network Native Driver for ESXi 😉

However, it turns out the pre-check is looking for PCIe-based network adaptors, so while the system does have two network adaptors, it still failed the pre-check and prevented the deployment from continuing. I ended up reaching out some of the VCF Engineers to see if there were any workarounds and he was kind enough to provide me with a nice workaround that would benefit our users looking to play and explore VCF in a lab environment.

Heads Up - Performance Impact with VMware Workstation on Windows 11 with Intel Hybrid CPUs

by // 11 Comments

There have been some recent reports from users observing performance issues when running VMware Workstation on Windows 11 along with using recent Intel (12th Gen and later) Hybrid CPUs, which introduces a new hybrid big.LITTLE architecture for Intel's x86 consumer CPUs.

This new Intel Hybrid CPU contains two types of CPU cores: Performance-cores (P-cores) and Efficiency-cores (E-cores) into the same physical CPU die, which follows a similar design to Apple Silicon CPUs. For information about the new Intel hybrid Intel CPUs, check out this resource HERE.

At first glance, most users had assumed this was due to Virtual Machines being scheduled to run on the less powerful E-Cores, this was problematic even for non-VMware use cases and with the recent introduction of Intel Thread Director, this was supposed to have been improved with Windows 11.

However, after some internal testing, the Intel Hybrid CPU may not actually be the culprit.

ESXi support for Intel iGPU with SR-IOV

by // 4 Comments

Support for Single Root I/O Virtualization (SR-IOV) was first introduced back in 2012 with the release of vSphere 5.1 and enables for a physical PCIe device to be shared amongst a number of Virtual Machines. The networking industry was the first to take advantage of the SR-IOV technology and could be used to help reduce latencies and improve overall CPU efficiencies for vSphere-based workloads that were network intensive.

Since SR-IOV is an extension of the PCIe specification, it can also be used benefit other non-networking devices. In 2016, AMD introduced their MxGPU technology which added SR-IOV capabilities to their GPUs which was then used to power VMware Horizon workloads, but this functionality was only available during the vSphere 6.0 and 6.5 release.

GPU sharing these days are synonymous to one vendor, NVIDIA. In 2015, VMware and NVIDIA teamed up to accelerate Enterprise desktop workloads through the integration of NVIDIA's vGPU (formally GRID) technology with the release of both VMware Horizon View and vSphere 6.0.

NVIDIA continues to dominate the GPU market in 2023, however another vendor has re-entered the market with an interesting solution that is enabled by the latest vSphere 8.0 Update 2 release ...
