As was said above, the sd card on the back of the machine is ONLY for use by the iDRAC. If you have iDRAC enterprise, it is not necessary to use it to install vmware esxi or for that matter any OS. All you need to do is mount the iso as a virtual disk using the iDRAC console. I do this all the time to both upgrade/install esxi and install centos/Windows/whatever vm's. Just do not try to mount the iso on a machine on a low bandwidth connection. It will take forever. :-( If you want to install vmware esxi on an sd card you need a isdm module. Something like: https://www.ebay.com/itm/PMR79-Dell-PowerEdge-R630-R730-R730xd-Dual-SD-Flash-Card-Reader-Module/233572427053?epid=1739290890&hash=item366200652d:g:YNQAAOSwBYhc3HPQ Keep in mind that Dell recommends that you do not install esxi newer than 6.7 on an sd card. They stopped offering the isdm modules on 14th gen servers with esxi 7.0 installed. They claim they see too many failures of the sd cards with 7.0. HTH, -- Tom me at tdiehl.org
