INSTALL VMWARE ESXI FROM USB TO ANOTHER USB INSTALL
On the Intel Xeon D-1500 systems I'm testing this fresh install procedure on, I'm delighted to say that it went well. Note, ESXi runs in RAM, so while boot times will be slightly slower off USB, once ESXi is booted, the operational speed won't be any different than if you installed to SATA, SAS, or even NVMe SSD. Once you're on this fresh install of 7.0 Update 1, I'd still recommend using vLCM to launch your ESXi host updates though, and if that doesn't work for you, there's always the old-standy-by single-liner ESXCLI update method. Also handy in single-host situations, where you might not even have the strongly-recommended VMware vSphere VCSA appliance with built-in vLCM (vSphere Lifecycle Manager) which currently supports Dell, HPE, and Lenovo firmware updates. This is particular important in a home lab environment where you might not have any VMware official support should things go sideways. One advantage of this USB approach is that you can easily image the drive before doing upgrades, allowing you a robust easy way to fall back should anything go wrong. This is a basic overview document of the fresh install process, highlighting the steps that I walk you right through in the accompanying video below, should work on any supported VMware ESXi server.
This article is still undergoing minor refinement based on further testing.
