I have a Dell r420 that i have been using since ESXi v5.1.
At that time, I recall Dell had the ESXi software that was to be installed on the server.
I used their version. Never noticed any Dell relate VMware messages.
Over the past years, I have used VMware ISOs to move to the ESXi 5.5 versions.
Today, I upgraded the r420 from 5.5 to 6.5 U1 using the option "Upgrade ESXi preserve VMFS datastore"
When I login to ESXi 6.5, I see the below information message on the 6.5 Web Client...
"You are running Dell Customized VMware ESXi 5.1.0 (VMKernel Release Build 799733)"
I am not sure if I need to remove something or reinstall and select the option to "Install ESXi preserve VMFS datastore" to
get rid of the Dell Customized VMware ESXi 5.1.0 version?
