I think the SD card on the back of the IDRAC7 systems on the Dell 730xd
similar to this. They are accessible by the IDrac and dell software and
primarily there for emergency install of the hardware from known good
media. I believe that vmware has a module which talks to the card so
can install software in vm's from said known good media.



You have anticipated what I am trying to do.  I have been using Centos
8 as a host on a 730xd machine, for some Centos 7 guests. With the end
of life of Centos 8 only 9 months away I decided to try to migrate
everything to vmware.  I purchased a sister 730xd to use as a lab
computer, and am working on the skill sets necessary  to migrate
everything to vmware. I have really grown to like kvm and am still
disappointed RedHat/IBM is backing away from Centos.  

I certainly have not been able to get Centos 8 to recognize the SD
card, and have also not been able to get vmware on the sister machine
to recognize either the SD card in the back slot or even when I have it
plugged into a usb converter.  The vmware problem is more likely
related to my lack of experience with vmware; this is my first time to
use it. 

Thank you for your help!!!!!
