Notes from the Field
vSphere 7.0 Update 2 and USB-based Boot Media (SD Cards/USB Sticks) – If your ESX hosts boot from these devices – you need to read this important information before you upgrade as the boot devices you are using may have issues.
vSphere 7 Update 2 introduces changes to core storage used by the Hypervisor and increases the I/O requirements past the endurance thresholds of some SD cards. This change is described in the vSphere 7.0 Update 2 VMware ESXi Installation and Setup Guide. On page 12 of the guide, it specifies that the ESX-OSData partition “must be created on high-endurance storage devices”.
Currently, information about the internal SD cards can’t be checked on the VMware Compatibility Guide, as hardware manufacturers do not provide that information to VMware. Please be aware that the hardware vendors are responsible for managing and updating their information listed in the compatibility guide. If you have questions about the endurance specifications of your SD Cards – please check with your hardware manufacturer.
KB 83376 – discusses the issues that can arise when the SD card boot device has exhausted its write capability. This KB also describes a work around VMware has developed to allow low endurance SD Cards to work with vSphere 7 Update 2. It involves a manual one-time config change which moves certain highly accessed files to a RAM Disk. This should become automatic in a future release of vSphere 7.x.
While this should help with vSphere 7.x, I am not sure what the future holds for SD Cards as ESX boot devices. If I had to guess, I would imagine that the I/O requirements will increase over time as ESX continues to evolve.
It is probably advisable to consider adding higher performance/endurance boot devices into a future budget or into your next hardware refresh plan.
