Greetings.
I am trying to understand if you are having trouble installing ESXi to your SD card after you've booted the install ISO, or you are having trouble getting the ESXi install ISO to boot up to begin with???
When you hit F6 during post time (after mounting ISO as CD/DVD virtual media), do you see the vKVM DVD listed? If you having issues getting the ISO to mount or boot, please confirm you have tested with several different ISO files, and also from a couple of different workstations. I have seen antivirus as well as MS GPO policies (removing USB device capabilities) cause problems actually getting the local ISO file to fully mount in the KVM.
Are you using a Java based KVM or the HTML based one?
There is a bug primarily listing blades, but it may impact rack servers as well regarding SD destinations for esxi 6.5 installs, https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvg50989/?reffering_site=dumpcr
I'm assuming you have the SD card boot order entry created, besides the local disk policy that enables the flexflash controller and specifies the raid type...
I see the TAC case you have open, and notice there are no logs attached.
Please generate a UCSM tech support, as well as a rack server tech support, and upload that to your case.
If you are looking to provision your regular HDDs and SSD drives, you can use a storage profile (contains Disk group policies where you define which drive slots, raid type, etc)
Thanks,
Kirk...
